Abstract

A new acylated triterpenoid saponin was obtained from the leaves of Sanicula europaea. The structure has been elucidated from NMR and MS data, and by chemical derivatisation as 21-O-[2-methylbutanoyl]-3 beta, 15 alpha, 16 alpha, 21 beta, 22 alpha, 28-hexahydroxyolean-12-ene 3-O-[alpha-L-arabinopyranosyl (1-->3)] beta-D-glucopyranosyl(1-->2)-beta-D-glucuronopyranoside.

摘要

从欧洲变豆菜的叶子中获得了一种新的酰化三萜皂苷。通过核磁共振（NMR）和质谱（MS）数据以及化学衍生化确定其结构为21-O-[2-甲基丁酰基]-3β，15α，16α，21β，22α，28-六羟基齐墩果-12-烯3-O-[α-L-阿拉伯吡喃糖基（1→3）]β-D-吡喃葡萄糖基（1→2）-β-D-吡喃葡萄糖醛酸苷。
