Abstract

Two new furostanol saponins were isolated from the fruits of Tribulus terrestris L. Their structures were established as 26-O-beta-D-glucopyranosyl-(25S)-5alpha-furost-20(22)-en-3beta,26-diol-3-O-alpha-L-rhamnopyranosyl-(1 --> 2)-[beta-D-glucopyranosyl-(1 --> 4)]-beta-D-galactopyranoside (1) and 26-O-beta-D-glucopyranosyl-(25S)-5alpha-furost-20(22)-en-12-one-3beta,26-diol-3-O-beta-D-galactopyranosyl-(1 --> 2)-beta-D-glucopyranosyl-(1 --> 4)-beta-D-galactopyranoside (2) on the basis of spectroscopic data as well as chemical evidence.

摘要

从刺蒺藜果实中分离出两种新的呋甾烷醇皂苷。基于光谱数据和化学证据，它们的结构被确定为26 - O - β - D - 吡喃葡萄糖基 - (25S) - 5α - 呋甾 - 20(22) - 烯 - 3β,26 - 二醇 - 3 - O - α - L - 吡喃鼠李糖基 - (1→2) - [β - D - 吡喃葡萄糖基 - (1→4)] - β - D - 吡喃半乳糖苷（1）和26 - O - β - D - 吡喃葡萄糖基 - (25S) - 5α - 呋甾 - 20(22) - 烯 - 12 - 酮 - 3β,26 - 二醇 - 3 - O - β - D - 吡喃半乳糖基 - (1→2) - β - D - 吡喃葡萄糖基 - (1→4) - β - D - 吡喃半乳糖苷（2）。
