Abstract

Two new tirucallane-type triterpenoid saponins, sapimukoside C (1) and sapimukoside D (2), have been isolated from the roots of Sapindus mukorossi Gaetn. Their structures have been determined, on the basis of spectral and chemical analysis, as 3-O-alpha-L-rhamnopyranosyl-(1-->2)-[alpha-L- arabinopyranosyl-(1-->3)]-beta-D-glucopyranosyl (21,23R)-epoxyl tirucalla-7,24-diene-(21S)-ethoxyl-3 beta-ol (1) and 3-O-alpha-L-rhamnopyranosyl-(1-->2)-[alpha-L-arabinopyranosyl-(1-->3)]- beta-D-glucopyranosyl (21,23R)-epoxyl tirucall-7,24-diene-(21S)-methoxyl-3 beta-ol (2).

摘要

从无患子（Sapindus mukorossi Gaetn.）的根部分离得到了两种新的四环三萜类皂苷，无患子皂苷C（1）和无患子皂苷D（2）。通过光谱和化学分析确定了它们的结构，分别为3-O-α-L-鼠李吡喃糖基-（1→2）-[α-L-阿拉伯吡喃糖基-（1→3）]-β-D-葡萄糖吡喃糖基（21,23R）-环氧-四环-7,24-二烯-（21S）-乙氧基-3β-醇（1）和3-O-α-L-鼠李吡喃糖基-（1→2）-[α-L-阿拉伯吡喃糖基-（1→3）]-β-D-葡萄糖吡喃糖基（21,23R）-环氧-四环-7,24-二烯-（21S）-甲氧基-3β-醇（2）。
