Abstract

The structure of a piscicidal triterpenoid saponin (saponin A) isolated from the leaves of Maesa ramentacea has been shown to be 3-O-[[(alpha-rhamnopyranosyl (1-->2)-alpha-L-rhamnopyranosyl(1-->2)-beta-D-galactopyranosyl (1-->3)]-[beta-D-glucopyranosyl(1-->2)]-beta-D-glucuronopyranosyl] barringtogenol C21, 22-O-diangeloate. Extensive use was made of homo- and heteronuclear 2D NMR techniques.

摘要

从山矾科植物薄叶山矾叶中分离得到的一种杀鱼三萜皂苷（皂苷A）的结构已被确定为3 - O - [[(α - 鼠李吡喃糖基(1→2) - α - L - 鼠李吡喃糖基(1→2) - β - D - 半乳吡喃糖基(1→3)] - [β - D - 葡糖吡喃糖基(1→2)] - β - D - 葡糖醛酸吡喃糖基]巴瑞托果醇C21, 22 - O - 二当归酸酯。广泛使用了同核和异核二维核磁共振技术。
