Abstract

Three new triterpenoid glycosides (XI, XII and XIII) were isolated from the ethanol extract of the roots of Dipsacus asper Wall. Their structures were deduced as 3-O-[beta-D-glucopyranosyl(1-->4)][alpha-L-rhamnopyranosyl (1-->3)]- beta-D-glucopyranosyl(1-->3)-alpha-L-rhamnopyranosyl(1-->2)-alpha- arabinopyranosyl-hederagenin (XI), 28-O-beta-D-glucopyranosyl(1-->6)-beta-D-glucopyranosyl ester of XI (XII) and 3-O-[beta-D-xylopyranosyl(1-->4)-beta-D-glucopyranosyl (1-->4)][alpha-L-rhamnopyranosyl(1-->3)]-beta-D-glucopyranosyl(1-->3)- alpha-L-rhamnopyranosyl(1-->2)-alpha-arabinopyranosyl-oleanolic.ac id 28-O-beta-D-glucopyranosyl(1-->6)-beta-D-glucopyranosyl ester (XIII), respectively, based on spectral and chemical analysis.

摘要

从糙叶川续断（Dipsacus asper Wall.）根的乙醇提取物中分离出三种新的三萜糖苷（XI、XII和XIII）。基于光谱和化学分析，它们的结构分别推导为3-O-[β-D-吡喃葡萄糖基(1→4)][α-L-吡喃鼠李糖基(1→3)]-β-D-吡喃葡萄糖基(1→3)-α-L-吡喃鼠李糖基(1→2)-α-L-阿拉伯吡喃糖基-常春藤皂苷元（XI）、XI的28-O-β-D-吡喃葡萄糖基(1→6)-β-D-吡喃葡萄糖基酯（XII）和3-O-[β-D-吡喃木糖基(1→4)-β-D-吡喃葡萄糖基(1→4)][α-L-吡喃鼠李糖基(1→3)]-β-D-吡喃葡萄糖基(1→3)-α-L-吡喃鼠李糖基(1→2)-α-L-阿拉伯吡喃糖基-齐墩果酸28-O-β-D-吡喃葡萄糖基(1→6)-β-D-吡喃葡萄糖基酯（XIII）。
