Objectives Several studies have attempted to prevent or improve oral mucositis (OM) but have not produced a qualified treatment yet. This study evaluates the effects of Carum carvi L. (caraway) hydroalcoholic extract (CHE) as one of the traditional medicinal plants in 5-fluorouracil (5-FU)-induced OM in golden hamsters. Materials and methods OM was induced in 54 male golden hamsters by 5-FU and cheek pouch scratching. Starting from day 12, 500 and 1000 mg kg−1 per day topical CHE were administered. Pouch histopathology score, malondialdehyde and reduced glutathione contents, and activity of myeloperoxidase plus microbial cultures of cheek pouch, antimicrobial properties of CHE, and essential oil constituents were evaluated. Results Lower histopathology score (0, 1, and 2) and malondialdehyde level, higher reduced glutathione level and activities of myeloperoxidase were detected in 1000 and 500 mg kg−1 per day topical CHE and control groups, respectively (P

This paper examines the effects of gluten-free bread enriched with functional ingredients (milk powder, poppy, sunflower and pumpkin seeds, egg yolk, carum, hazel nuts and amaranth) on the morphological and biochemical parameters and antioxidant status of rats serum. Rats were provided test diets – gluten-free breads and water ad libitum . After 14 days, the animals were weighed and killed. A hazel nut-amaranth bread diet significantly increased the level of thrombocytes when compared to control bread. A mixed bread diet significantly decreased cholesterol levels in rats. All fortified breads decreased triglyceride levels and alanine transaminase activity and caused an increase in antiradical activity of the serum. In rats fed with poppy-milk bread, milk-seed bread and mixed bread, a marked decrease in superoxide dismutase activity was found. Enriched breads reduced the levels of triglyceride and improved the antiradical properties of serum, although the physiological relevance of this needs to be confirmed by human studies.

This review summarizes literature related to medicinal plants reputed in traditional medical systems for treatment of asthma and coughs. The plants that are pharmacologically investigated for their effectiveness in such conditions, along with respective experimental protocol details, are also discussed. Some of plant origin compounds, which are considered useful as antitussive and antiasthmatic agents, are described as well. Chrysoeriol, a constituent of Aspalathus linearis (Fabaceae) was observed to be selective for relaxant effect in airways (through K+ channel activation), compared with other smooth muscles. We reported that Hypericum perforatum (Hyperieaceae), Andropogon muricatus (Poaceae), Juniper excelsa (Coniferae) and Nepeta cataria (Lamiaceae) exhibit bronchodilatory action, mediated through combination of Ca++ antagonist and phospohodiesrase inhibitory mechanisms, which scientifically explains their medicinal use in asthma. Hyocyamus niger (Solanaceae), Artemisia vulgaris (Compositae), Fumaria parviflora (Fumariaceae) and Terminalia bellerica (Combretaceae) caused bronchodilation via dual blockade of muscarinic receptors and Ca++ influx. Acorus calamus (Araceae), Carum roxburghianum (Apiaceae), Lens culinaris (Fabaceae) and Lepidium sativum (Cruciferae) mediate bronchodilatation through multiple pathways: anticholinergic and inhibition of Ca++ channels and PDE enzyme(s). In conclusion, this review presents an analysis of different novel combinations of pharmacological activities in medicinal plants with side effect-neutralizing/synergistic potential, setting new trends in the therapeutic options for hyperactive respiratory disorders such as asthma and cough.

Carum copticum seeds have been prescribed in the traditional system of medicine for the treatment of immune disorders, such as asthma and rheumatism.The objective of this study was to determine immunomodulatory effects of the alcoholic extract and isolated compounds in Swiss albino mice.Seeds of C. copticum were extracted with 95% v/v alcohol. The immunomodulatory activity of the crude extract was evaluated at the doses of 100, 300, and 500 mg/kg body weight of mice, administered in mice once daily (orally) for 25 days. Volatile oil of C. copticum was isolated by steam distillation and was characterized by GLC and HPLC. Bio-assay-guided fractionation and isolation were carried out and the isolated compounds were characterized and subjected to immunomodulatory activity studies.The n-hexane fraction yielded p-cymene, carvacrol, and α-pinene. The LD50 value of the crude extract was found to be 4500 mg/kg and the values reported for p-cymene, carvacrol, and α-pinene in the literature were 4750, 810, and 3700 mg/kg, respectively. The oral administration of crude extract, n-hexane fraction (HEF), and isolated oils at the dose of 500, 150, and 50 mg/kg body weight, respectively, showed a significant increase in the HA titers, DTH-response, and phagocytosis. The stimulatory effect observed, on humoral and cellular immunity, was compared with the standard (levamisole treated) and control groups.The results obtained in the study endorse the traditional use of the seeds of C. copticum and the isolated constituents act as immunostimulants.

Adaptive neuro-fuzzy computing technique in estimating the anti-obesity.Property of a potent medicinal plant in a clinical dietary intervention.Reduction in body mass index (BMI), body fat percentage, and body weight loss.Anti-obesity activities of caraway (Carum carvi) a traditional medicine on obese women. This research examines the precision of an adaptive neuro-fuzzy computing technique in estimating the anti-obesity property of a potent medicinal plant in a clinical dietary intervention. Even though a number of mathematical functions such as SPSS analysis have been proposed for modeling the anti-obesity properties estimation in terms of reduction in body mass index (BMI), body fat percentage, and body weight loss, there are still disadvantages of the models like very demanding in terms of calculation time. Since it is a very crucial problem, in this paper a process was constructed which simulates the anti-obesity activities of caraway (Carum carvi) a traditional medicine on obese women with adaptive neuro-fuzzy inference (ANFIS) method. The ANFIS results are compared with the support vector regression (SVR) results using root-mean-square error (RMSE) and coefficient of determination (R2). The experimental results show that an improvement in predictive accuracy and capability of generalization can be achieved by the ANFIS approach. The following statistical characteristics are obtained for BMI loss estimation: RMSE=0.032118 and R2=0.9964 in ANFIS testing and RMSE=0.47287 and R2=0.361 in SVR testing. For fat loss estimation: RMSE=0.23787 and R2=0.8599 in ANFIS testing and RMSE=0.32822 and R2=0.7814 in SVR testing. For weight loss estimation: RMSE=0.00000035601 and R2=1 in ANFIS testing and RMSE=0.17192 and R2=0.6607 in SVR testing. Because of that, it can be applied for practical purposes.

In recent years, the unparalleled and functional properties of essential oils have been extensively reported, but the sensitivity of essential oils to environmental factors and their poor aqueous solubility have limited their applications in industries. Hence, we encapsulated CEO in chitosan nanoparticles by an emulsion-ionic gelation with pantasodium tripolyphosphate (TPP) and sodium hexametaphosphte (HMP), separately, as crosslinkers. The nanoparticles were analyzed by Fourier transform infrared spectroscopy (FT-IR), Ultraviolet-visible spectroscopy (UV-vis), differential scanning calorimetry (DSC), scanning electron microscope (SEM) and dynamic light scattering (DLS). The encapsulation efficiency (EE) and loading capacity (LC) of CEO in chitosan nanoparticles increased with the increase of initial CEO amount. The nanoparticles displayed an average size of 30-80nm with a spherical shape and regular distribution. In vitro release profiles exhibited an initial burst release and followed by a sustained CEO release at different pH conditions. The amount of CEO release from chitosan nanoparticles was higher in acidic pH to basic or neutral pH, respectively. The biological properties of CEO, before and after the encapsulation process were evaluated by 2,2-diphenyl-1-picrylhydrazyl radical (DPPH) and agar disk diffusion method, respectively. The results indicated the encapsulation of CEO in chitosan nanoparticles could be protected the quality.

Following the increasing antibiotic resistance of pathogenic bacteria, the use of medicinal herbs as antibacterial agents has attracted growing attention. Pseudomonas aeruginosa is a human opportunistic pathogen that uses quorum sensing for regulating virulence gene expression (pyocyanin, protease, and elastase production and biofilm formation). This study examined the anti-quorum sensing activity of Quercus infectoria, Zataria multiflora and Trachyspermum copticum extracts on standard P. aeruginosa strain. The minimum inhibitory concentration (MIC) of Q. infectoria, Z. multiflora and T. copticum extracts for standard P. aeruginosa strain was determined through micro dilution. Microtiter plates were used to evaluate the anti-quorum sensing effects of the three extracts (at a sub-MIC concentration) on pyocyanin, protease, and elastase production and biofilm formation. The acetone extract of Q. infectoria showed the highest anti-quorum sensing activity and reduced the pyocyanin, protease, and elastase production and biofilm formation by 89.1%, 78%, 73.3%, and 70.1%, respectively. The corresponding values were 88.2%, 72.1%, 69%, and 61.1% for the methanol extract of Z. multiflora and 70.6%, 63.42%, 60.1%, and 59.1% for the methanol extract of T. copticum. Considering the high anti-quorum sensing activity of the studied extracts, especially the acetone extract of Q. infectoria, these herbs can be used as antipathogenic drugs.

The objectives of this study were to develop a new assay for the evaluation of the antimicrobial activities of essential oils (EOs) in vapour phase and to demonstrate the antimicrobial activities of commercial EOs against BRPs. To achieve the first objective, a microtube cap containing 100 μl of EO was embedded in an agar plate. An agar plug (diameter 13 mm) inoculated with a bacterial suspension containing108 CFU per ml was then placed over the cap and incubated at 37°C for 24 h. Subsequently, bacteria were recovered from the agar plug by immersion in 5 ml of broth for 10 min, followed by vortexing for 30 s, and the broths were then plated for enumeration. To demonstrate the usefulness of the assay, nine commercial EOs derived from the following specific plants: ajowan, carrot seed, cinnamon leaf, citronella, fennel, ginger grass, lavender, rosemary and thyme were first evaluated for their vapour phase antimicrobial activities against Mannheimia haemolytica serotype 1. Selected EOs were further tested against Pasteurella multocida and Histophilus somni. The EOs of ajowan, thyme and cinnamon leaf completely or partially inhibited BRPs growth. This new assay provided reproducible results on the vapour phase antimicrobial activities of EOs against BRPs. These results support further study of EOs as a potential mitigation strategy against BRPs. Significance and Impact of the Study In this study, we present a new vapour phase assay for evaluating the antimicrobial activities of essential oils (EO) against bovine respiratory pathogens (BRPs). Using this assay, we identified EOs, such as ajowan, thyme and cinnamon leaf, that can effectively inhibit growth of the BRPs Mannheimia haemolytica serotype 1, Pasteurella multocida and Histophilus somni. This is the first study to demonstrate the vapour phase antimicrobial activity of EOs against BRPs.

Cumin is a plant of the Apiaceae family (umbelliferae) which has been used since ancient times as a medicinal plant and as a spice. The difference in the percentage of aromatic compounds in cumin obtained from different locations has led to differentiation of some species of cumin from other species. The quality and price of cumin vary according to the specie and may be an incentive for the adulteration of high value samples with low quality cultivars. An electronic nose simulates the human olfactory sense by using an array of sensors to distinguish complex smells. This makes it an alternative for the identification and classification of cumin species. The data, however, may have a complex structure, difficult to interpret. Given this, chemometric tools can be used to manipulate data with two-dimensional structure (sensor responses in time) obtained by using electronic nose sensors. In this study, an electronic nose based on eight metal oxide semiconductor sensors (MOS) and 2D-LDA (two-dimensional linear discriminant analysis), U-PLS-DA (Partial least square discriminant analysis applied to the unfolded data) and PARAFAC-LDA (Parallel factor analysis with linear discriminant analysis) algorithms were used in order to identify and classify different varieties of both cultivated and wild black caraway and cumin. The proposed methodology presented a correct classification rate of 87.1% for PARAFAC-LDA and 100% for 2D-LDA and U-PLS-DA, indicating a promising strategy for the classification different varieties of cumin, caraway and other seeds.

The current review emphasizes on the herbal bioenhancers which themselves do not possess inherent pharmacological activity of their own but when co-administered with Active Pharmaceutical Ingredients (API), enhances their bioavailability and efficacy. Herbal bioenhancers play a crucial role in enhancing the bioavailability and bioefficacy of different classes of drugs, such as antihypertensives, anticancer, antiviral, antitubercular and antifungal drugs at low doses. This paper highlights various natural compounds that can be utilized as an efficient bioenhancer. Several herbal compounds including piperine, quercetin, genistein, naringin, sinomenine, curcumin, and glycyrrhizin have demonstrated capability to improve the pharmacokinetic parameters of several potent API. This article also focuses on various United States patents on herbal bioenhancers, which has proved to be beneficial in improving oral absorption of nutraceuticals like vitamins, minerals, amino acids and certain herbal compounds. The present paper also describes proposed mechanism of action, which mainly includes absorption process, drug metabolism, and action on drug target. The herbal bioenhancers are easily available, safe, free from side effects, minimizes drug toxicity, shortens the duration of treatment, lowers the drug resistance problems and minimizes the cost of treatment. Inspite of the fact that herbal bioenhancers provide an innovative concept for enhancing the bioavailability of several potent drugs, there are numerous bioenhancers of herbal origin that are yet to be explored in several vital areas. These bioenhancers must also be implied to enhance the bioavailability and bioefficacy through routes other than the oral route of drug delivery. There is a vast array of unexploited plants which can be investigated for their drug bioenhancing potency. The toxicity profiles of these herbal bioenhancers must not be overlooked. Researches must be carried out to solve these issues and to deliver a safe and effective dose of drugs to attain desired pharmacological response.

The systematic position of three Apiaceae taxa, Carum piovanii , Bunium nothum and Bunium kandaharicum , is clarified based on morphological and nrITS sequence data. The phylogenetic analyses place C. piovanii within the African peucedanoid genus, Afroligusticum and not with its congeners. Although C. piovanii differs considerably from Afroligusticum in underground organs (spindle-shaped or subcylindrical tubers vs. rhizomatous woody rootstocks), size of leaflets (up to 4 mm long vs. over 8 mm long), and petal color (white vs. mostly greenish or yellow), it is similar carpologically (obtuse-keeled dorsal ribs and narrowly-winged marginal ribs). As a result the new combination Afroligusticum piovanii is proposed. A new section, Austrobunium , is described to accommodate the South Indian B. nothum based on the well-developed calyx teeth not found in the rest of the genus. The Afghanian species, B. kandaharicum , is reduced into synonym with Elwendia stewartiana .

Emergence of drug-resistant strains has demanded for alternative means of combating fungal infections. Oils of Carum copticum and Thymus vulgaris have long been used in ethnomedicine for ailments of various fungal infections. Since their activity has not been reported in particular against drug-resistant fungi, this study was aimed to evaluate the effects of oils of C. copticum and T. vulgaris on the growth and virulence of drug-resistant strains of Aspergillus spp. and Trichophyton rubrum. The gas chromatography-mass spectrometry analysis revealed thymol constituting 44.71% and 22.82% of T. vulgaris and C. copticum, respectively. Inhibition of mycelial growth by essential oils was recorded in the order of thymol > T. vulgaris > C. copticum against the tested strains. RBC lysis assay showed no tested oils to be toxic even up to concentration two folds higher than their respective MFCs. Thymol exhibited highest synergy in combination with fluconazole against Aspergillus fumigatus MTCC2550 (FICI value 0.187) and T. rubrum IOA9 (0.156) as determined by checkerboard method. Thymol and T. vulgaris essential oil were equally effective against both the macro and arthroconidia growth (MIC 72 μg/mL). A > 80% reduction in elastase activity was recorded for A. fumigatus MTCC2550 by C. copticum, T. vulgaris oils and thymol. The effectiveness of these oils against arthroconidia and synergistic interaction of thymol and T. vulgaris with fluconazole can be exploited to potentiate the antifungal effects of fluconazole against drug-resistant strains of T. rubrum and Aspergillus spp.

In current study, we describe blood pressure (BP)-lowering, endothelium-dependent, and independent vasodilator and cardio-modulatory actions of Carum roxburghianum seed. The crude extract of C. roxburghianum seed (Cr.Cr) induced dose-dependent (10-100 mg/kg) fall in arterial BP of anaesthetized rats. In isolated rabbit aorta, Cr.Cr (0.3-10 mg/mL) inhibited high K+ (80 mM) and phenylephrine (PE, 1 µM)-induced contractions, like verapamil and papaverine. In endothelium-intact rat aortic preparations, Nω-nitro-L-arginine methyl ester hydrochloride-sensitive vasodilator activity was observed with Cr.Cr, which also relaxed endothelium-denuded aorta tissues. In guinea-pig atria, Cr.Cr initially caused mild cardiac stimulation, followed by inhibition, as shown by papaverine. These results reveal that cardiovascular effects of C. roxburghianum seed extract are mediated possibly through combination of Ca++ antagonist, nitric oxide modulating and phosphodiesterase inhibitory mechanisms, though further in-depth studies are required for elucidating precise mode of action.

Thymoquinone (TQ) from black caraway seeds has several anticancer activities; however, its effect on triple-negative breast cancer (TNBC) cells that lack functional tumor suppressor p53 is not known. Here, we explored the growth inhibitory effect of TQ on 2 TNBC cell lines with mutant p53. Cell metabolism assays showed that TQ inhibited TNBC cell growth without affecting normal cell growth. Flow cytometric analyses of TQ-treated TNBC cells showed G1 phase cell cycle arrest and apoptosis characterized by the loss of mitochondrial membrane integrity. Western blots of lysates from TQ-treated TNBC cells showed cytochrome c and apoptosis-inducing factor in the cytoplasm, as well as caspase-9 activation consistent with the mitochondrial pathway of apoptosis. Caspase-8 was also activated in TQ-treated TNBC cells, although the mechanism of activation is not clear at this time. Importantly, TQ-induced apoptosis was only partially inhibited by zVAD-fmk, indicating a role for caspase-independent effector molecules. Poly(ADP-ribose) polymerase cleavage and increased γH2AX, as well as reduced Akt phosphorylation and decreased expression of X-linked inhibitor of apoptosis, were evident in TQ-treated cells. Finally, TQ enhanced cisplatin- and docetaxel-induced cytotoxicity. These findings suggest that TQ could be useful in the management of TNBC, even when functional p53 is absent.

This study was conducted to evaluate the antibacterial effect of Carum copticum essential oil (Ajowan EO) against Listeria monocytogenes in fish model system. Ajowan EO chemical composition was determined by gas chromatography/mass spectral analysis and the highest concentration of Carum copticum essential oil without any significant changes on sensory properties of kutum fish (Rutilus frisii kutum) was assigned. Then the inhibitory effect of Ajowan EO at different concentrations in presence of salt and smoke component was tested on L. monocytogenes growth in fish peptone broth (FPB), kutum broth and cold smoked kutum broth at 4 ºC for 12 days. Ajowan EO completely decreased the number of L. monocytogenes in FPB after 12 days of storage, however, antimicrobial effect of EO significantly reduced in kutum and cold smoked kutum broth. Addition of 4% NaCl and smoke component improved the anti-listerial activity of Ajowan EO in all fish model broths.

The volatile compounds of the essential oils of Carum roxburghianum Benth. (Radhuni) seeds of three different ecotypes of Bangladesh were obtained by hydrodistillation method and maximum yield was 2.57 % (w/w). The oils were analyzed by GC and GC-MS and thirty volatile compounds were identified and quantified. Predominantly monoterpene hydrocarbon accounted for 59.27-91.11 % of the total oil. The major constituents of the oils were limonene (29.33-59.37 %), 5,7,8-trimethyl-dihydrocoumarin (11.5326.69 %), sabinene (2.49-17.43 %), γ-terpinene (4.10-10.13 %), p-cymene (3.20-7.67 %), apoil (0.5-7.11 %), terpenolene (1.09-7.03 %), β-cis-caryophyllene (2.07-5.42 %), terpinene-4-ol (0.07-5.11 %), cis-sabinene hydrate (3.78-4.89 %), α-phellandrene (0.05-3.54%) and myristicine (0.28-2.33 %). The highest concentration of the elements (in ppm) were Ca 18900, Mg 6900, P 5500, K 5000, S 2900, Na 2000, Zn 115.0, Fe 105.0, B 43.0, Cr 0.561, Ni 0.464, Pb 0.042 and Co 0.033 in the three studied ecotypes. The Physico-chemi...

Loop-mediated isothermal amplification (LAMP) is a DNA-based analytical method that can be used as an isothermal alternative to polymerase chain reaction (PCR). In comparison to PCR, the advantage of LAMP is the possibility to perform the isothermal reaction without any sophisticated technical equipment; only a water bath is needed, and naked eye detection is sufficient. Up to now, an application of LAMP methods for the detection of even closely related plant species in food or feed matrices has not been described, whereas a large number of PCR methods for that topic are cited in the literature. The aim of the study was the evaluation of LAMP-based methods for plant species identification with respect to method parameters such as R(2), LOD, and LOQ. An existing (real-time) PCR method (for the detection of spices) was used for comparison. It could be shown that the developed LAMP methods have potential as alternative strategies to PCR in DNA-based analysis.

UNLABELLED Carum copticum and Ferula assafoetida have several medicinal properties including antispasmodic, carminative, sedative, analgesic, and antiseptic. Reactive oxygen species (ROS), reactive nitrogen species (RNS), hydrogen peroxide (H(2) O(2) ), and thiobarbituric acid reactive substances (TBARS) scavenging activities of Carum and Ferula oils along with their antibacterial and antifungal activities were examined. Thymol (40.25%), γ-terpinene (38.7%) and p-cymene (15.8%) were detected as the main components of Carum oil while, β-pinene (47.1%), α-pinene (21.36%), and 1, 2-dithiolane (18.6%) were the main components of Ferula oil. Inhibitory concentrations (IC50) for total radical scavenging were between 40 and 60 and 130 and 160 μg/mL of Carum and Ferula oil, respectively. Minimal inhibitory concentration (MIC) for Salmonella typhi, Escherichia coli, Staphylococcus aureus, Bacillus subtilis, Aspergillus niger, and Candida albicans were 78 ± 8, 65 ± 7, 14 ± 3, 5 ± 2, 5.6 ± 1.3, and 8.8 ± 2.2 μg/mL of Carum oil, respectively. MIC for S. typhi, E. coli, S. aureus, B. subtilis, A. niger, and C. albicans were >200, >200, 125 ± 17, 80 ± 12, 85 ± 5, and 90 ± 11 μg/mL of Ferula oil, respectively. Accordingly, Carum and Ferula oils could be used as safe and effective natural antioxidants to improve the oxidative stability of fatty foods during storage and to preserve foods against food burn pathogens. PRACTICAL APPLICATION This study clearly demonstrates the potential of Carum and Ferula oil especially Carum oil as natural antioxidant and antimicrobial agent. The chemical composition of essential oils was identified. Thus, identification of such compounds also helps to discover of new antioxidant, antibacterial and antifungal agents for potential applications in food safety and food preservation.

Ajowan (Trachyspermum ammi L.) spice has been used in food preparations and also as a traditional medicine in Ayurveda. Although a number of pharmacological activities have been attributed to ajowan, its role in immunomodulation is not known. The main objective of the present study is to examine the macromolecular immunomodulatory components. Macrophage activation was studied by nitric oxide (NO) release, phagocytosis and secretion of pro-inflammatory cytokines as the markers. Ethanol precipitate (fractional) of ajowan aqueous extract was subjected to conventional chromatography (Q Sepharose followed by Bio-Gel P-100). One of the proteins (30.7 kDa; ajowan glycoprotein or Agp) showed effective mitogenic activity towards splenocytes. Agp is a O-linked glycoprotein with the glycans contributing to one-third of the molecular mass. It has a high content of glutamic acid, serine, aspartic acid and proline whereas galactose (45.7%), arabinose (34.5%), glucose (7%), mannose (5%) and xylose (4%) are the constituent sugars. Secondary structure analysis indicated that Agp contains 79% α-helices and 21% random coil. Internal sequencing of the tryptic peptides did not show homology with the existing proteins in the database (BLAST). Agp at 1 μg/mL induced proliferation of B-cell enriched murine splenocytes and activated macrophages in releasing NO and promoted phagocytosis (p

The aim of this research was to prepare of bionanocomposite films based on chitosan (CH) incorporated with Carum copticum essential oil and reinforced with cellulose nanofibers (CNF) or lignocellulose nanofibers (LCNF). The FTIR analysis showed new interactions in bionanocomposites. AFM and SEM analyses showed an increased roughness for bionanocomposites but suggested good dispersion of CNF and LCNF in CH matrix. X-ray diffraction confirmed that the degree of crystallinity was increased by addition of CNF/LCNF. The results suggested that the CH-EO film had high antioxidant activity and was more effective against E. coli and B. cereus bacteria than CH-EOCNF and CH-EO-LCNF films, which shows the release controlling effect of nanofibers. Mechanical properties were improved with addition of EO and CNF/LCNF. Incorporation of EO and CNF/LCNF improved water vapor barrier properties of films. In general, uniform dispersion and improving effect of LCNF on properties of CH-EO films was more than CNF.

Direct analysis in real time mass spectrometry (DART-MS) was applied as a rapid method for the discrimination of the spices and traditional medicines cumin (Cuminum cyminum L.), caraway (Carum carvi L.), and fennel (Foeniculum vulgare Mill.). The seeds of these plants were analyzed without sample preparation by DART ion source coupled with quadrupole time-of-flight (QTOF) tandem mass spectrometry. The relatively clean DART spectra showed characteristic patterns, fingerprints, for each herb. It was found that a marker compound can be assigned to each species that can identify unambiguously these plants. Principal component analysis has also been used to analyze the DART-MS data of these seed herbs. Crispanone, carvone, and fenchone are the dominant compounds in the positive DART spectra of cumin, caraway, and fennel, respectively. Crispanone was first time identified as a constituent of cumin. Furthermore, the collision-induced dissociation (CID) behavior of the [M+NH4]+ ion of crispanone was also described.

Many essential oils and their terpene constituents display antimicrobial properties, which may affect rumen metabolism and influence milk production parameters. Many of these compounds also have distinct flavors and aromas that may make their way into the milk, altering its sensory properties. Essential oils from caraway (Carum carvi) seeds and oregano (Origanum vulgare) plants were included in dairy cow diets to study the effects on terpene composition and sensory properties of the produced milk, as well as feed consumption, production levels of milk, and methane emissions. Two levels of essential oils, 0.2 and 1.0 g of oil/kg of dry matter, were added to the feed of lactating cows for 24 d. No effects on feed consumption, milk production, and methane emissions were observed. The amount and composition of volatile terpenes were altered in the produced milk based on the terpene content of the essential oils used, with the total amount of terpenes increasing when essential oils were added to the diet. Sensory properties of the produced milk were altered as well, and milk samples from animals receiving essential oil treatment were perceived as having a fresher aroma and lower stored aroma and flavor. The levels of essential oils used in this study mimic realistic levels of essential oils in herbs from feed, but were too low to affect milk production and methane emissions, and their inclusion in the animal diet did not adversely affect milk flavor.

Background Herbal distillates have been used as beverages, for flavoring, or as phytomedicines in many countries for a long time. Recently, the occurrence of blindness after drinking herbal distillates has created concerns in Iran. The aim of this study was to determine the concentrations of methanol in herbal distillates produced in Iran. Methods Eighty-four most commonly used herbal distillates purchased from herbal distillate factories were analyzed for methanol contents by gas chromatography and flame ionization detection, with ethanol as internal standard. Results In 15 herbal distillates, the methanol concentration was below the limit of quantitation. The methanol concentrations in all samples ranged from 43 to 277 mg/L. Forty-five samples contained methanol in excess of the Iranian standard. The maximum concentration was found in an herbal distillate of Mentha piperita (factory E) (277±12), and the minimum in a distillate of Carum carvi (factory B) (42.6 ± 0.5). Conclusions Since the 45 Iranian herbal distillates containing methanol levels were beyond the legal limits according to the Iranian standard, it seems necessary to monitor the amount of methanol and give a warning to watch out for the latent risk problem of methanol uptake, and establish a definitive relationship between the degree of intoxication observed and the accumulation of methanol in the blood.

We have recently reported that the inhibition of colonic premalignant lesions induced by 1,2-dimethylhydrazine (DMH) is mediated by the interference of caraway oil components in the activities of the main hepatic xenobiotic metabolizing enzymes. The present study was carried out to examine the effect of dietary caraway oils on the progression of cancer, with emphasis on β-catenin expression in the colon during DMH-induced colonic carcinogenesis. For this purpose, colon cancer was induced by DMH in rats (20 mg/kg body weight for 5 weeks) and groups of animals were given dietary caraway essential oils at two levels (0.01 and 0.1%) for 16 weeks. After 16 weeks and at the end of the experimental period the colon tissue biopsies were processed for histopathological examination and the expression of β-catenin at mRNA and protein levels was estimated by polymerase chain reaction and enzyme-linked immunosorbent assay. The formation of premalignant lesions based on aberrant crypt foci (ACF) in DMH-treated rats was greatly inhibited (72-87%) in rats given dietary essential oils when compared to respective controls. There was a correlation between the number of colonic ACF formation and the expression levels of β-catenin measured at protein and mRNA levels. These results indicate that the Wnt/β-catenin signaling pathway is activated during colon cancer promotion and that the expression of colonic β-catenin is altered in long-term caraway oil feeding, leading to suppression of DMH-induced premalignant lesions in rat colon.

The biopesticidal potential of six plant-derived essential oils (mint [ Mentha arvensis ], ajwain [ Carum capticum ], lemongrass [ Cymbopogon citrates ], clove [ Eugenia caryophyllata ], cedarwood [ Cedrus deodara ], and eucalyptus [ Eucalyptus globulas ]) was evaluated against Odontotermes obesus (termites), Fusarium oxysporum (plant pathogenic fungi), and Meloidogyne incognita (nematodes). In the case of termites, a “no-choice” bioassay revealed that the mint oil gave the best results (100% mortality in 30 min with 10% oil and in 10 h with 0.12% oil) followed by the lemongrass and ajwain oils. The disc diffusion method was adopted to test the anti-fungal activity of the essential oils and it was found that the clove oil gave the maximum inhibition measured in terms of the average inhibition zone diameter (5.3 ± 0.2 cm with 10% oil and 6.6 ± 0.9 cm with 20% oil), followed by the ajwain oil. To check the anti-nematicidal activity of the essential oil, in-vitro growth chamber experiments revealed that eucalyptus oil was the most efficient (100% mortality in 6 h with 1000 μl l −1 oil and in 30 h with 125 μl l −1 oil), followed by the ajwain oil. The use of the crude oils at low concentrations provided satisfactory results at the laboratory level against these pathogens, and needs further evaluation in field trials.

Recently, the natural spices and herbs such as rosemary, oregano, and caraway have been used for the processing of meat products. This study investigates the antioxidant activity of 13 spices commonly used in meat processing plants. The hot water extracts were then used for evaluation of total phenolic content, total flavonoids content and antioxidant activities. Our results show that the hot water extract of oregano gave the highest extraction yield (41.33%) whereas mace (7.64%) gave the lowest. The DPPH radical scavenging ability of the spice extracts can be ranked against ascorbic acid in the order ascorbic acid > clove > thyme > rosemary > savory > oregano. The values for superoxide anion radical scavenging activities were in the order of marjoram > rosemary > oregano > cumin > savory > basil > thyme > fennel > coriander > ascorbic acid. When compared to ascorbic acid (48.72%), the hydroxyl radical scavenging activities of turmeric and mace were found to be higher (p < 0.001). Clove had the highest total phenolic content (108.28 μg catechin equivalent (CE)/g). The total flavonoid content of the spices varied from 324.08 μg quercetin equivalent (QE)/g for thyme to 3.38 μg QE/g for coriander. Our results indicate that hot water extract of several spices had a high antioxidant activity which is partly due to the phenolic and flavonoid compounds. This provides basic data, having implications for further development of processed food products.

During our screening program for agrochemicals from Chinese medicinal herbs and wild plants, the essential oil of Carum carvi fruits was found to possess strong contact toxicity against Sitophilus zeamais and Tribolium castaneum adults, with LD50 values of 3.07 and 3.29 mg/adult, respectively, and also showed strong fumigant toxicity against the two grain storage insects with LC50 values of 3.37 and 2.53 mg/L, respectively. The essential oil obtained by hydrodistillation was investigated by GC and GC-MS. The main components of the essential oil were identified to be (R)-carvone (37.98%) and D-limonene (26.55%) followed by α-pinene (5.21), cis-carveol (5.01%) and b-myrcene (4.67%). (R)-Carvone and D-limonene were separated and purified by silica gel column chromatography and preparative thin layer chromatography, and further identified by means of physicochemical and spectrometric analysis. (R)-Carvone and D-limonene showed strong contact toxicity against S. zeamais (LD50 = 2.79 and 29.86 mg/adult) and T. castaneum (LD50 = 2.64 and 20.14 mg/adult). (R)-Carvone and D-limonene also possessed strong fumigant toxicity against S. zeamais (LC50 = 2.76 and 48.18 mg/L) and T. castaneum adults (LC50 = 1.96 and 19.10 mg/L).

Objective: The present communication is based on herb, namely, Trachyspermum ammi L. belonging to family Apiaceae, commonly known as “Ajowan” or carom seeds, and green tea (Camellia sinensis, Theaceae) for the prevention of intoxication induced with a sublethal dose of diazinon.Methods: Male mice weighing around 6.5 mg/kg body weight were exposed to diazinon, a common pesticide used in plant cultivation. Carom seed and green tea leave extracts were given thereafter to the male mice to check their effect on the toxicity of diazinon.Results: After several weeks of exposure to these herbal extracts, there was a significant change observed in the hematobiochemical parameters with a significant increase in values of serum alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transferase, alkaline phosphatase, creatine kinase, creatinine, glucose, and cholesterol. In contrast, no significant statistical difference was perceived in the values of all hematobiochemical parameters in mice treated with tea leaves extract, carom seed extract, and tea leave and carom seed extracts except the value of serum cholesterol in mice treated with carum seed extract which decreased as compared to the control group.Conclusion: These findings suggest the importance of the carom seeds and green tea and their combinatorial usage against diazinon toxicity, thus promising these plant products to be promising therapeutic agents against hepatotoxicity, cardiotoxicity, nephrotoxicity, and metabolic disorders due to diazinon toxicity. This also makes the safety of herbal products an important public health issue.

BACKGROUND: The present study describes the chemical analysis of the essential oil and oleoresins from caraway, which have been studied by using GC–MS. The paper also explains the importance of the extracted oil and oleoresins in the antioxidant activities of target plant species. RESULTS: GC–MS analysis of caraway essential oil showed 51 compounds representing about 96.6% of the total weight. The major components were dillapiole (44.6%), germacrene-β (14.1%), nothoapiole (8.3%), and β-selinene (6.8%), along with many other components in minor amounts. Major components in ethyl acetate and iso-octane oleoresins are dillapiole, nothoapiole and germacrene-β, whereas in ethanol oleoresin contains dillapiole (25%), sitosterol (21.3%) stigmasterol (9.5%) and nothoapiole (8.1%). The antioxidant activity was evaluated by various antioxidant assays such as peroxide, thiobarbituric acid and p-anisidine values. These experiments were further supported by other complementary antioxidant assays such as ferric thiocyanate method in linoleic acid system, reducing power, and scavenging effects on 1,1′-diphenyl-2-picrylhydrazyl (DPPH). Both the caraway volatile oil and its oleoresins showed strong antioxidant activity in comparison with butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT). CONCLUSION: This study provides additional information about the chemistry and antioxidant activity of caraway. Hence, caraway may be used as natural food preservatives.

BACKGROUND: The essential oil and fatty acid composition of Tunisian annual caraway (Carum carvi L.) seeds from three ecotypes was investigated by gas chromatography and gas chromatography–mass spectrometry analyses. RESULTS: Total fatty acid (TFA) proportion of caraway seeds varied from 2.95% to 5.68% (w/w). The fatty acid composition revealed that Tunisian caraway seed oil is rich in an unusual fatty acid—petroselinic acid—the proportion of which varied from 31.53% and 38.36% of TFA. Essential oil yields were relatively low and ranged from 0.86% to 1.20% (w/w). Forty-one volatile compounds were identified, the main ones being carvone (76.78–80.53%) and limonene (13.05–20.29%). CONCLUSION: Tunisian caraway seed oil is rich in an unusual fatty acid—petroselinic acid—which is of potential industrial significance. In addition, Tunisian caraway essential oil is carvone chemotype. This fact is of great economic interest due to the several applications of carvone in the alimentary and medicinal industries.

The volatile constituents of the aerial parts of Carum montanum (Coss. et Dur.) Benth. et Hook. were analysed by GC-FID and GC-MS, and the main component was isolated and identified as nothoapiole. The antibacterial and antifungal activities of this compound and of the total oil were investigated against Gram-negative (P. aeruginosa, E. coli), Gram-positive (E. faecalis, S. aureus, S. epidermitis, S. saprophyticus, S. simulans, S. lugdunensis) bacteria and on one strain of fungus (C. tropicalis).

Aims There are many biological investigations for determining an effective cure for the dysfunction of gastrointestinal tracts, using herbal medicine. It has been reported that Carum Copticum is a bactericidal agent and possesses anticholinergic, antihistaminic and b-adrenergic stimulatory effects in some tissues. However, these effects of Carum Copticum on mechanical activities of isolated intestine are not clearly identified yet. The present study has been designed to find out the specific effects of Carum Copticum on mechanical activity of isolated rat's ileum. Materials and Methods In this study rat's ileum contraction was recorded through an isolated tissue chamber in an organ bath by using isotonic transducer and oscillographic device. The effect of Carum Copticum extract on acetylcholine induced contraction in isolated rat's ileum was evaluated. Results Our findings showed that 1% aqueous extract of Carum Copticum reduces the basal contractile activity of rat's ileum. The extract also reduced acetylcholine induced contraction to 40% of its maximum response. The inhibitory action of Carum Copticum extract on acetylcholine induced contraction was similar but slower than that of atropine sulfate. Conclusion The results of this study showed an inhibitory effect of Carum Copticum extract on acetylcholine induced contraction in rat's ileum.

Essential oil from the leaves and fruits of Carum roxburghianum Benth. is analyzed by gas chromatography-mass spectrometry (GC-MS). The oil leaf is dominated by apiol (20.81%), 2(3H)-furanone,dihydro-5-pentyl- (17.21%), 1,3-benzodioxole, 4-methoxy-6-(2-propenyl)- (9.51%) and citronellol (6.62%). The fruit oil is rich in 2-cyclohexen-1-one, 2-methyl-5-(1-methylethenyl)- (40.03%), and other components that follow are apiol (18.71%), limonene (17.11%), myristicin (12.30%), dihydrocarvone (7.89%) and eugenol (1.68%). The compositions of both oils vary qualitatively and quantitatively.  Keywords : Carum roxburghianum ; Essential oil; GC-MS analysis; Apiol , 2-cyclohexen-1-one; 2-methyl-5-(1-  methylethenyl)-.  © 2009 JSR Publications.

A preliminary study was conducted to investigate the effects of the extracts of eight plant species collected from Ninavah governorate on the second instar of larval stage of Culex pipiens molestus Forskal. Three out of the eight plant extracts Azadirachta excelsa Jack, Cleome glaucescens Dc. and Quercus infectoria DL. caused 100% mortality of larvae at a concentration of 200 µg/mL after 3days of treatment. The LC50 values were less than 150µg/mL (62.5µg/mL-140µg/mL). The A. excelsa leave extract showed mortality on larval and pupal at low concentrations 40µg/mL-10µg/mL also affected in delaying larval development. The extracts of Achillea santolina L., Ammi majus L. and Ricinus communis L. caused high mortality to the larvae after 7 days of treatment, but the Datura stramonium L. and Carum petroselinum Benth extracts did not cause any mortality to the larvae at the same date.

The various solvent fractions of star-anise ( Illicium verum ) and black caraway ( Carum nigrum ), along with their spice powders and volatile oils, were prepared and evaluated for antioxygenic activity, using different methods. Star-anise powder and its ethanol/water (80:20)-soluble fraction showed strong antioxygenic activity in refined sunflower oil while the petroleum ether fraction exhibited marginal antioxygenic activity and the water-soluble fraction was practically devoid of any activity in sunflower oil. The black caraway powder showed marginal antioxygenic activity while its ethanol/water fraction (80:20) showed strong antioxygenic activity and all other fractions showed slight pro-oxygenic activity in refined sunflower oil. Both the spice powders and their extracts were also evaluated for antioxidant activity by linoleic acid peroxidaton, β-carotene-linoleate and 1, 1-diphenyl-2-picryl hydrazyl (DPPH) methods. Both the star-anise and black caraway powders, as well as their ethanol/water extracts, exhibited strong antioxygenic activity. Volatile oils from both the spices exhibited antioxygenic activity and the activity did not seem to be concentration-dependent. Volatile oils from star-anise showed relatively higher antioxygenic activity than did those from black caraway. Gas chromatography–mass spectroscopy (GC–MS) studies on star-anise and black caraway volatile oils resulted in the identification of 25 and 22 compounds, respectively, representing 94–97% of the total content.

Following the current 'Globesity' trend, there is an increasing demand for alternative natural therapies for weight management. Numerous phytoconstituents reduce body weight through suppressing appetite and reducing food intake. Caraway (Carum carvi L.) is one of the medicinal plants that is traditionally used for weight loss. In this study, the appetite-suppressing effects of caraway aqueous extract (CAE) on 70 aerobically trained, overweight, and obese women were examined in a triple-blind, placebo-controlled, clinical study. Subjects were randomly allocated into placebo and experimental groups and consumed either 30 mL/day of CAE or placebo without changing their diet or physical activity over a period of 90 days. Calorie and macronutrient intake and anthropometric indices were measured before and after the intervention. In addition, appetite changes were assessed through a visual analog scale and an ad libitum pizza test. After the intervention, the results showed a significant reduction in appetite levels and carbohydrate intake of the experimental group compared with the placebo group. All of the anthropometric indices were reduced significantly in CAE compared with placebo group (p 0.01). These preliminary outcomes suggest that a dietary CAE might be effective in weight management of physically active, adult females, reducing their body size and hunger level.

A novel technique using maghemite nanoparticle-decorated hollow fibers to assist electromembrane extraction is proposed. Electromembrane extraction combined with dispersive liquid-liquid microextraction (EME-DLLME) was applied for the extraction of thymol from Carum copticum, followed by gas chromatography with flame ionization detection (GC-FID).The use of maghemite nanoparticle-decorated hollow fibers was found to improve the extraction efficiency of thymol significantly. Important operational parameters, including pH of acceptor phase, extraction time, voltage and temperature, were investigated and optimized. At the optimal conditions, linearity in the range 4-1800 µg LThe results indicated that EME-DLLME/GC-FID is a useful technique for the extraction and determination of thymol in C copticum. © 2016 Society of Chemical Industry.

Carum carvi is a widely available herb that has been used as a food additive and as a medication in traditional medicine for many years. Its potential biological effects include analgesic, anti-inflammatory, anti-anxiety and antispasmodic activities. We report a patient with papillary thyroid carcinoma who were under treatment with levothyroxine and experienced an elevated TSH level by ingestion of Carum carvi. TSH level was increased to 60.3 mIU/L with no change in levothyroxine dosage and decreased to normal range after discontinuation of the Carum carvi. Observing this dramatic change in TSH level by carum ingestion, carum carvi capsules was produced and one of the researcher tried the medication on herself with a dose of 40 mg/kg/day. She had a history of hypothyroidism and was taking 100 ugr/day of levothyroxine. TSH was markedly increased 2 weeks after ingestion of Carum carvi and returned to normal range 5 months after discontinuation of it. This case report shows the effect of consumption of Carum carvi in increasing TSH level in hypothyroid patients treating with levothyroxine. The exact mechanism of action of carum carvi remains unknown.
