【摘要】 目的:对黄鳝藤药材(根和茎)进行生药鉴定,为进一步研究和利用黄鳝藤奠定基础。方法:采用性状鉴别、显微鉴别、薄层色谱方法对黄鳝藤药材进行生药鉴定。结果:黄鳝藤根的横切面呈偏心型,次生韧皮部纤维成群分布;有2种形态石细胞分别分布于根和茎中;得到了根和茎的薄层色谱图。结论:黄鳝藤根和茎显微特征明显,可作为该药材鉴定的参考依据,槲皮素是区分根与茎的特征性成分。更多还原

【Abstract】 Objective: To study the pharmacognostical characteristics of stem and root of Berchemia floribunda for its further research and usage. Methods: The plant was researched by macroscopic identification,microscopic identification and thin layer chromatography. Results: The transverse section of B. floribunda root was eccentric. There were many fiber bundles in the secondary phloem and two different stone cells distributed in stem and root respectively. The results of TLC could identify the stem and root of B. floribunda. Conclusion: The microscopic characteristics of B. floribunda stem and root can be used as reference for its identification. Quercetin can be used as the characteristic component to identify the stem and root.更多还原
