  Cucurbitane-Type Triterpenoids fromMomordica charantia

  摘要：

  AbstractThe six new cucurbitane‐type triterpenoids 1–6, along with the ten known triterpenoids 7–16, were isolated from the vines and leaves of Momordica charantia. The structures of the new compounds were elucidated as (3β,7β,15β,23E)‐3,7,15,25‐tetrahydroxycucurbita‐5,23‐dien‐19‐al (1), (3β,7β)‐3,7,22,23‐tetrahydroxycucurbita‐5,24‐dien‐19‐al (2), (3β,7β)‐3,7,23,24‐tetrahydroxycucurbita‐5,25‐dien‐19‐al (3), (3β,7β,23S)‐3,7,23‐trihydroxycucurbita‐5,24‐dien‐19‐al 7‐β‐D‐glucopyranoside (4), (3β,7β,23E)‐cucurbita‐5,23‐diene‐3,7,19,25‐tetrol 7‐β‐D‐glucopyranoside (5), and (3β,7β,23E)‐3,7‐dihydroxy‐25‐methoxy‐cucurbita‐5,23‐dien‐19‐al 3‐β‐D‐allopyranoside (6), by extensive analyses of their spectral data, as well as by chemical methods.
