Abstract

Three new cucurbitane‐type triterpenoid saponins, 23‐O‐β‐D‐allopyranosyl‐5β,19‐epoxycucurbita‐6,24‐diene‐3β,22(S),23(S)‐triol‐3‐O‐β‐D‐glucopyranoside (1), 23‐O‐β‐D‐allopyranosyl‐5β,19‐epoxycucurbita‐6,24‐diene‐3β,22(S),23(S)‐triol‐3‐O‐β‐D‐allopyranoside (2), and 23‐O‐β‐D‐allopyranosyl‐5β,19‐epoxycucurbita‐6,24‐diene‐3β,19(R), 22(S),23(S)‐tetraol‐3‐O‐β‐D‐allopyranoside (3), named momordicoside M, N, and O, respectively, along with one known saponin momordicoside L (4), were isolated from the fresh fruits of Momordica charantia. The structures of these saponins were elucidated on the basis of chemical properties and spectral data. Copyright © 2007 John Wiley & Sons, Ltd.
