A new C30 sterol glycoside from the fresh fruits of Momordica charantia

摘要: 目的:研究新鲜苦瓜中的化学成分。方法:采用硅胶柱色谱和ODS柱色谱进行化学成分分离纯化,并利用波谱数据分析和理化性质进行结构鉴定。结果:从新鲜苦瓜中分离得到1个新C30甾醇苷,结构鉴定为25-异丙烯-胆甾-5,(6)-烯-3-O--D-吡喃葡萄糖苷(1)。结论:化合物1为新的C30甾醇苷。

Abstract: AIM: To investigate the chemical constituents from the fresh fruits of Momordica charantia L. METHODS: Chemical constituents were isolated and purified by chromatography on silica gel and octadecylsilanized (ODS) silica gel, and the structures were determined by spectral data and chemical evidence. RESULTS: A new C30 sterol glycoside, named 25-isopropenylchole-5, (6)-ene-3-O--D-glucopyranoside (1), was isolated from the fresh fruits of M. charantia L. CONCLUSION: Compound 1 is a new C30 sterol glycoside.
