| 1 | An HPLC Fingerprint Identification of Dried Barks of Ilex rotunda and Ilex godajam显示文摘[Objectives] A simple and reliable HPLC fingerprint method was developed for the identification of dried barks of Ilex rotunda and I. godajam. [Methods] Nine batches of dried barks of I. rotunda,and seven batches of dried barks of I. godajam collected from different pharmacies and arboretums in different regions of China were used to establish fingerprints. The software Similarity Evaluation System of Chromatographic Fingerprints of Traditional Chinese Medicine( 2004 A Edition) was used to evaluate the fingerprints. [Results]The fingerprints of dried barks of I. rotunda and I. godajam were established. Methodological study met the technical requirements of fingerprints. The similarities of the fingerprints of dried barks of I. rotunda and I. godajam were all more than 0. 8 and 0. 9 respectively. There were 31 and 28 common peaks in I. rotunda and I. godajam,which could be classified into two clusters by principal component analysis( PCA) and hierarchical cluster analysis. [Conclusions] The feasibility and advantages of used HPLC fingerprints were verified,and the results indicated that the HPLC fingerprint as a characteristic distinguishing method combining similarity evaluation,principal component analysis and hierarchical cluster analysis can be successfully used to identify the authenticity of dried barks of I. rotunda and I. godajam. | Yucui MA Chun WANG Wei WANG Cui WU Ning DU Wen SUN Hui LI Zhimao CHAO | 2018 | Medicinal Plant2018，9，3： | 0 |
| 2 | System Control Research of Multi-link Fructus Trichosanthis Quality显示文摘It could not guarantee the quality of medicinal materials and decoction pieces to purely make quality standard of traditional Chinese medicine and carry out quality control. For the problems existed in each process and link of traditional Chinese medicine production,control techniques and measures of guaranteeing and improving quality should be proposed,thereby forming process control system for quality of each traditional Chinese medicine. Based on systemic research on Fructus Trichosanthis which is common traditional Chinese medicine more than30 years,the concept of establishing process control system of Fructus Trichosanthis quality is proposed firstly in this paper. The research aims to find quality problems from 10 processes and links( plant variety,cultivation and propagation,field pest control,fruiting and maturity degree of fruit,storage,regulator,chemical ingredient,quality standard,limited index and circulation),and form feasible techniques and measures solving problems in each process and link,thereby systemically guaranteeing the quality of Fructus Trichosanthis medicinal material and decoction pieces. It guarantees and improves clinical efficacy of Fructus Trichosanthis in Chinese medicine,and could provide reference for establishing process control system of quality of other traditional Chinese medicines. | Cui WU Yucui MA Zhimao CHAO | 2017 | Medicinal Plant2017，8，3： | 0 |
