【摘要】 从四川蜘蛛抱蛋(Aspidistra sichuanensis K.Y.Lang et Z.Y. Zhu)根状茎中分离得到三个甾体皂甙,经光谱和化学方法分别鉴定为22-甲氧基-5β-呋喃甾烷-1β,3β,4β,5β,26-五羟基26-O-β-D-毗喃葡萄糖甙(1),蜘蛛抱蛋皂甙(2)和原蜘蛛抱蛋皂甙(3)。(1)是一个呋喃甾醇型单糖链的新皂甙,(3)是本植物的主要皂甙。更多还原

【Abstract】 Three steroidal glycosides were isolated from the rhizome of Aspidistra sichuanensis K. Y. Lang et Z. Y. Zhu. Their structures were established to be 22-methoxy-53-furostane-13,23,33,53,26-pentaol 26-O-β-D-glucopyr-anoside,aspidistrin and proto-aspidistrin on the basis of chemical and spectral evidences. The first saponin is a new furostanol glycoside.更多还原
