Abstract

Three new minor steroidal saponins, (25R) 5 alpha-spirostan-3 beta-o1-6-one-3-O-[alpha-L-arabinopyranosyl(1-4)-beta-D- glucopyranoside, (25S) spirost-5-en-3 beta, 27-diol-3-O-[alpha-L-arabinopyranosyl (1-6)]-beta-D-glucopyranoside, and (25S) spirost-5-en-3 beta, 17 alpha, 27-triol-3-O-[alpha-L-arabinopyranosyl (1-6)]-beta-D-glaucopyranoside, were isolated from the root of Similax lebrunii, in addition to two known steroidal glycosides. Their structures were elucidated on the basis of chemical and spectral methods.

摘要

除了两种已知的甾体苷外，从短柄菝葜的根中还分离出三种新的次要甾体皂苷，即(25R)5α-螺甾烷-3β-醇-6-酮-3-O-[α-L-阿拉伯吡喃糖基(1→4)-β-D-吡喃葡萄糖苷]、(25S)螺甾-5-烯-3β,27-二醇-3-O-[α-L-阿拉伯吡喃糖基(1→6)]-β-D-吡喃葡萄糖苷和(25S)螺甾-5-烯-3β,17α,27-三醇-3-O-[α-L-阿拉伯吡喃糖基(1→6)]-β-D-吡喃葡萄糖苷。它们的结构通过化学和光谱方法得以阐明。
