Abstract

Besides two known glycosides, a new furostanol glycoside was isolated from the Fruits of Tribulus terrestris L. The structure of the new furostanol glycoside was established as 26-O-beta-D-glucopyranosyl-(25S)-5alpha-furostane-20(22)-en-12-one-3beta, 26-diol-3-O-alpha-L-rhamnopyranosyl-(1-->2)-[beta-D-glucopyranosyl-(1-->4)]-beta-D-galactopyranoside (1) on the basis of 1D and 2D-NMR techniques, including COSY, HMBC, and HMQC correlations.

摘要

除了两种已知的糖苷外，从蒺藜果实中分离得到了一种新的呋甾烷醇糖苷。新呋甾烷醇糖苷的结构被确定为 26-O-β-D-吡喃葡萄糖基-(25S)-5α-呋甾烷-20(22)-烯-12-one-3β,26-二醇-3-O-α-L-鼠李吡喃糖基-(1-->2)-[β-D-吡喃葡萄糖基-(1-->4)]-β-D-半乳糖吡喃糖苷（1），这是基于 1D 和 2D-NMR 技术，包括 COSY、HMBC 和 HMQC 相关。
