Norcucurbitane triterpenoids from the fruits of Momordica charantia var. abbreviata

Nat Prod Commun. 2013 Jan;8(1):79-81.

Abstract

Two new 27-norcucurbitane triterpenoids, 27-nor-3beta-hydroxy-7beta-methoxycucurbita-5,23(E)-dien-25-one (1) and 27-nor-3beta-hydroxy-5beta,19-epoxycucurbita-6,23(E)-dien-25-one (2), together with two known cucurbitane triterpenes, 23(E)-7beta-methoxycucurbita-5,23,25-trien-3beta-ol (3) and 5beta,19-epoxy-25-methoxycucurbita-6,23(E)-dien-3beta-ol (4), were isolated from the fruits of Momordica charantia var. abbreviata. Their structures were determined by analysis of spectroscopic data and comparison with the data of known analogues.
