Abstract

Three new glycosides named anguiviosides A-C were isolated from the fruits of Solanum anguivi and characterized as follows:3-O-beta-chacotrioside (1), 3-O-[4-O-maloyl-alpha-L-rhamnopyranosyl(1-->2)]-alpha-L-rhamnopyra nosyl(1-->4)-beta-D-glucopyranoside (2) and 3-O-alpha-L-rhamnopyranosyl(1-->2)-beta-D-xylopyranosyl(1-->3)]-beta-D-+ ++glucopyranoide (3), of (25R,26R)-spirost-5-en-3beta,26-diol.

摘要

从刺茄果实中分离出三种新的糖苷，命名为刺茄苷A - C，其结构特征如下：3 - O - β - 查考三糖苷（1）、3 - O - [4 - O - 丙二酰基 - α - L - 鼠李吡喃糖基(1→2)] - α - L - 鼠李吡喃糖基(1→4) - β - D - 吡喃葡萄糖苷（2）和3 - O - α - L - 鼠李吡喃糖基(1→2) - β - D - 木吡喃糖基(1→3)] - β - D - 吡喃葡萄糖苷（3），均为(25R,26R) - 螺旋甾 - 5 - 烯 - 3β,26 - 二醇的衍生物。
