Abstract

Background: Gentiana crassicaulis () is an important traditional Chinese herb. Like other herbs, its chemical compounds vary greatly by the environmental and genetic factors, as a result, the quality is always different even from the same region, and therefore, the quality evaluation is necessary for its safety and effective use. In this study, a comprehensive method including HPLC quantitative analysis and fingerprints was developed to evaluate the quality of Cujingqinjiao and to classify the samples collected from Lijiang City of Yunnan province. A total of 30 common peaks including four identified peaks, were found, and were involved for further characterization and quality control of Cujingqinjiao. Twenty-one batches of samples from Lijiang City of Yunnan Province were evaluated by similarity analysis (SA), hierarchical cluster analysis (HCA), principal component analysis (PCA) and factor analysis (FA) according to the characteristic of common peaks. Results: The obtained data showed good stability and repeatability of the chromatographic fingerprint, similarity values were all more than 0.90. This study demonstrated that a combination of the chromatographic quantitative analysis and fingerprint offered an efficient way to quality consistency evaluation of Cujingqinjiao. Consistent results were obtained to show that samples from a same origin could be successfully classified into two groups. Conclusion: This study revealed that the combinative method was reliable, simple and sensitive for fingerprint analysis, moreover, for quality control and pattern recognition of Cujingqinjiao. SUMMARY HPLC quantitative analysis and fingerprints was developed to evaluate the quality of Gentiana crassicaulisSimilarity analysis, hierarchical cluster analysis, principal component analysis and factor analysis were employed to analysis the chromatographic dataset.The results of multi-components quantitation analysis, similarity analysis, hierarchical cluster analysis, principal component analysis and factor analysis were consistent.All samples could be classified into two groups, which could to some extent reflect the quality differences of theses samples. Abbreviations used: SA: Similarity analysis, HCA: Hierarchical cluster analysis, PCA :Principal component Analysis, FA :Factor analysis

Abstract

ABSTRACTChitinase plays an important role in plant resistance against chitin-containing pathogens through hydrolysis of chitin. Clubroot caused by Plasmodiophora brassicaeis a major disease for cruciferous crops and vegetables worldwide. The cell wall of P. brassicaeresting spores contains chitin. Chitinase is regarded as capable of improving plant resistance to fungal diseases. However, there has been no report about the function of chitinase in P. brassicae. Here, wheat germ agglutinin staining and commercial chitinase treatment demonstrated that chitin is a functional component in P. brassicae. In addition, Chitinase PbChia1 was identified by chitin pull-down assay combined with LC-MS/MS. PbChia1 was found to be a typical secreted chitinase, which could bind chitin with chitinase activity in vitro. PbChia1 could significantly decrease the resting spores of P. brassicaeand therefore relieve the severity of clubroot symptom, with a biocontrol effect of 61.29%. Overexpression of PbChia1in Arabidopsis thalianaimproved its resistance to P. brassicae, increased host survival rate and seed yield, enhanced PAMPs-triggered reactive oxygen species burst, MAPK activation and expression of immune-related genes. PbChia1transgenic plants also showed resistance to other pathogens, such as biotrophic bacterium PstDC3000, necrotrophic fungi Sclerotinia sclerotiorumand Rhizoctonia solani. These findings indicate that chitinase PbChia1is a candidate gene that can confer broad-spectrum disease resistance in breeding.

32. A comparison of volatile fractions obtained from Lonicera macranthoidesvia different extraction processes: ultrasound, microwave, Soxhlet extraction, hydrodistillation, and cold maceration

Author

Wu, Chun, Wang, Feng, Liu, Jiang, Zou, Yuanfeng, and Chen, Xingfu

Abstract

Hydrodistillation has been traditionally used to extract volatile fraction in traditional Chinese medicine. However, with the development of Soxhlet extraction (SE), microwave (MW), ultrasound (US), and cold maceration (CM), hydrodistillation (HD) is being replaced to meet some practical requirements. In this study, we investigated the effect of the five methods on the volatile fraction extract of Lonicera macranthoides.
