Abstract

Two new triterpenoidal saponins were isolated from the n-butanolic extract of Stachys parviflora (Lamiaceae). Their structures were elucidated on the basis of spectral data as stachyssaponin A; 3beta, 15alpha, 19alpha, 21beta, 22alpha-pentahydroxyolean-12-ene-28-oic acid 3-O-{alpha-L-rhamnopyranosyl-(1 --> 3)-beta-D-glucopyranoside}-22-O-{alpha-L-arabinofuranosyl-(1 --> 3)-beta-D-glucopyranoside} (1) and stachyssaponin B; 2beta, 3beta, 15alpha, 21beta-tetrahydroxyolean-12-ene-28-oic acid 2-O-[alpha-L-arabinofuranoside]-3, 21-bis-O-[beta-D-glucopyranoside] (2).

摘要

从细叶水苏（唇形科）正丁醇提取物中分离出两种新的三萜皂苷。根据光谱数据确定它们的结构分别为水苏皂苷A：3β,15α,19α,21β,22α-五羟基齐墩果-12-烯-28-酸3-O-{α-L-鼠李糖基-(1→3)-β-D-葡萄糖苷}-22-O-{α-L-阿拉伯呋喃糖基-(1→3)-β-D-葡萄糖苷}（1）和水苏皂苷B：2β,3β,15α,21β-四羟基齐墩果-12-烯-28-酸2-O-[α-L-阿拉伯糖苷]-3,21-二-O-[β-D-葡萄糖苷]（2）。
