Abstract

Crataegus monogyna is an important plant of the Rosaceae family, widely used in traditional medicine to treat various conditions such as cardiovascular diseases, cancer, diabetes, asthma, and nephritis. The aim of the current study was to assess the chemical composition, antioxidant, and antibacterial activity of leaves’ extracts against Bacillus cereus, Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa. The total amounts of polyphenols and flavonoids contained in the dry extracts of plants were estimated by colorimetric methods. DPPH assay was utilized to measure the antioxidant activity of C. monogyna. The phytochemical compounds were determined through HPLC technique, and the minimum inhibitory concentration (MIC) of ethanol extract was performed using the broth dilution method. The ethanol extract represented the richest extract in polyphenol with 473.4 mg GAE g−1 and flavonoids 80.9 mg CE g−1 and showed considerable antioxidant potential IC50 =22.50 µg/ml. The antibacterial susceptibility test against Staphylococcus aureus 0.512 mg/mL.

Abstract

The essential oils of plants have been widely recognized in the pharmaceutical industry due to their various benefits as well as their biological activities. In Algeria, the seeds of Foeniculum vulgare Mill (Family Apiaceae) are widely utilized in herbal medicine. We aimed to examine the chemical composition of seed essential oil of this species, and to reveal its in vitro antifungal activity against Candida albicans, Aspergillus flavus, Aspergillus niger, Rhizopus sp., Trichophyton rubrum, Trichophyton mentagrophytes, Trichophyton violaceum, Microsporumgypseum, Microsporumcanis and Rhodotorula sp. Chemical analysis of essential oil isolated by hydro-distillation was carried out by GC–FID and GC–MS. The basic components of the essential oil were estragole (84.8%), limonene (7.8%), fenchone (3.1%) and α-pinene (1.3%). The essential oil of F. vulgare revealed higher antifungal activities particularly against C. albicans and Aspergillus species with MIC values of 0.16–0.2 mg/ml.

Abstract

Chemical composition determination and in vitro antibacterial effect of Essential Oil (EO) of Laurus nobilis leaves grown North West Algerian conditions were investigated. Antibacterial activity was evaluated by the technique of the paper disc diffusion. Extractions were carried out with Clevenger apparatus and EO compositions were investigated by gas chromatography coupled to mass spectrometry (GC-MS) analysis. The oxygenated monoterpenes (MO) were the class with the highest contents, represent 59% of the EO. A total of twenty-seven of these compounds were identified, the major components were 1,8-cineole (30.1%), α-terpynil acetate (21.6%), methyl eugenol (16.9%) of the total oil. The highest antibacterial power of the EO tested was recorded in Streptococcus faecalis and Staphylococcus aureus with the zone diameter of inhibition 13.6 and 11.2 mm respectively and a minimal inhibitory concentration (MIC) of 0.25 mg/mL for both these two strains.
