Abstract

Two novel triterpenoid saponins, named mussaendosides U and V, together with one known saponin and four known triterpenes were isolated from the aerial parts of Mussaenda pubescens (Rubiaceae). The structures were determined on the basis of chemical analysis ad spectral methods. All these compounds were identified for the first time from the genus Mussaenda.

摘要

从茜草科玉叶金花的地上部分分离得到了两种新型三萜皂苷，分别命名为玉叶金花苷U和V，同时还得到了一种已知皂苷和四种已知三萜。通过化学分析和光谱方法确定了它们的结构。所有这些化合物均首次从玉叶金花属中鉴定得到。
