Three new triterpene glycosides, named momordicosides C, D and E, were isolated from the seeds of Momordica charantia L. (Cucurbitaceae). Their structures were determined on the basis of spectral and chemical evidence as 3-O-β-gentiobiosides of cucurbit-5-ene-3β, 23, 24, 25-tetraol, cucurbita-5, 24-diene-3β, 22, 23-triol and 3β-hydroxy-23, 24, 25, 26, 27-pentanor-20 (ε)-cucurbit-5-en-22-al, respectively.
                                    从苦瓜(Momordica charantia L.,葫芦科)种子中分离出了三种新型三萜苷,命名为momordicosides C、D和E。根据光谱和
化学证据,其结构分别确定为3-O-β-gentiobioside的葫芦烯-3β, 23, 24, 25-四醇、葫芦烯-3β, 22, 23-三醇和3β-羟基-23, 24, 25, 26, 27-中戊-20(ε)-葫芦烯-22-醛。
