摘要: Five new cucurbitane-type triterpenes, (23E)-25-methoxycucurbit-23-ene-3 beta,7 beta-diol (1), (23E)-cucurbita-5,23,25-triene-3 beta,7 beta-diol (2), (23E)-25-hydroxycucurbita-5,23-diene-3,7-dione (3), (23E)-cucurbita-5,23,25-triene-3,7-dione (4), and (23E)-5 beta,19-epoxycucurbita-6,23-diene-3 beta,25-diol (5), together with one known triterpene, (23E)-5 beta,19-epoxy-25-methoxycucurbita- 6,23-dien-3 beta-ol (6), have been isolated from the methanol extract of the stems of Momordica charantia. The structures of the new compounds were elucidated by spectroscopic methods.
