摘要

Three new cucurbitane-type triterpenoids, 5β,19-epoxy-23(R)- methoxycucurbita-6,24-dien-3β-ol (1), 5β,19-epoxy-23(S)- methoxycucurbita-6,24-dien-3β-ol (2), and 3β-hydroxy-23(R)- methoxycucurbita-6,24-dien-5β,19-olide (3), were isolated from the fruit pulp of Momordica charantia. Their structures were established on the basis of extensive NMR (1H, 13C, COSY, HMQC, HMBC, and NOESY) and EI-MS studies. Compound 1 exhibited cytotoxic activity against the SK-Hep 1 cell line.
