OBJECTIVE
To isolate and identify steroidal saponins from the rhizomes of Dioscorea septemloba Thunb.
METHODS
The compounds were isolated by solvent extraction, column chromatography on silica gel and ODS, and their structures were elucidated on the base of chemical and spectral analyses.
RESULTS
Three steroidal saponins were isolated from the rhizomes of Dioscorea septemloba Thunb, and their structures were detemined as dioscin (I), protodioscin (II), protogracillin (III).
CONCLUSION
Compound II and III were obtained from the rhizomes of Dioscorea septemloba Thunb for the first time.
目的
从绵萆薢根茎中分离并鉴定甾体皂苷。
方法
采用溶剂萃取、硅胶柱色谱和ODS柱色谱法分离化合物，并通过化学和光谱分析确定其结构。
结果
从绵萆薢根茎中分离出三种甾体皂苷，其结构分别确定为薯蓣皂苷（I）、原薯蓣皂苷（II）、原纤细皂苷（III）。
结论
化合物II和III首次从绵萆薢根茎中获得。
