Abstract

Two new triterpenoid saponins, named mussaendosides G and K, were isolated from aerial parts of Mussaenda pubescens by normal and reverse phase chromatography. On the basis of chemical and spectroscopic methods, their structures have been elucidated as heinsiagenin A 3-O-{alpha-L-rhamnopyranosyl(1-->2)-[beta-D-glucopyranosyl (1-->6)]-beta-D-glucopyranosyl(1-->2)}-alpha-L -rhamnopyranosyl(1-->4)-O-beta-D-glucopyranoside and 3 beta,19 alpha-dihydroxyl-olean-12-en-24, 28-dioic acid-24,28-di-O-beta-D-glucopyranoside, respectively.

摘要

通过正相和反相色谱法，从玉叶金花的地上部分分离出两种新的三萜皂苷，分别命名为玉叶金花苷G和K。基于化学和光谱方法，它们的结构已被阐明，分别为海因皂苷元A 3 - O - {α - L - 鼠李吡喃糖基(1→2)-[β - D - 葡萄糖吡喃糖基(1→6)] - β - D - 葡萄糖吡喃糖基(1→2)}-α - L - 鼠李吡喃糖基(1→4)-O - β - D - 葡萄糖苷和3β,19α - 二羟基 - 齐墩果 - 12 - 烯 - 24,28 - 二酸 - 24,28 - 二 - O - β - D - 葡萄糖苷。
