贵州产菝葜属及肖菝葜属8个品种的鉴别研究

Pharmacognosy Research of 8 Varieties from Smilax and Heterosmilax Native in Guizhou Province

目的系统研究贵州产菝葜属(SmilaxL.)及肖菝葜属(HeterosmilaxK.)常见8个品种的药材性状特征。方法用TLC鉴别该类品种的指标性成分落新妇苷、白藜芦醇及薯蓣皂苷元。结果在药材性状特征上建立了检索表,为该类品种的性状特征提供了专属性的鉴别依据。薄层鉴别中菝葜属及肖菝葜属常见8个品种均含有落新妇苷及白藜芦醇,但仅3个品种含薯蓣皂苷元,即短梗菝葜、黑叶菝葜及小叶菝葜,而药典品种菝葜及土茯苓则未检测出薯蓣皂苷元。结论该研究方法重复性及专属性较好,简单易行,可为该类品种的新资源开发利用及品种间鉴别提供一定的参考依据。

Objective To study macroscopic characteristic of 8 varieties of red,white Tufuling in Guizhou.Methods TLC method was used to identify the key composition resveratrol and diosgenin.Results Based on the macroscopic characteristic,we established the identification key,and offered a basis for the proprietary identification among the 8 species.All of the 8 species contained resveratrol.Only three of them contained diosgenin,they were S.scobinincaulis,S.nigrescens and S.microphylla,but we did not found diosgenin in S.china and S.glabra which included in Chinese pharmacopiea.Conclusion Our method in this study is simple,accurate and reproducible and can provide some reference for development and identification of new medicinal resources.
