从斯里兰卡栽培的瓜类植物Momordica charantia L.（葫芦科）果实中分离到2个新的瓜烷型三萜：卡拉维苷D和E，以及6个新的瓜烷型三萜苷：卡拉维苷VI、VII、VIII、IX、X和XI。根据化学和物理化学证据对它们的结构进行了分析。
Two new cucurbitane-type triterpenes, karavilagenins D and E, and six new cucurbitane-type triterpene glycosides, karavilosides VI, VII, VIII, IX, X, and XI, were isolated from the fruit of Momordica charantia L. (Cucurbitaceae) cultivated in Sri Lanka. Their structures were elucidated on the basis of chemical and physicochemical evidence.
