Abstract

Two new triterpenoids, 3β-hydroxytirucall-7,25-dien-24-one (1) and 3β-acetoxytirucall-7,23,25-triene (2), along with one new sesquiterpenoid, alloaromadendrane-12α,14β-dioic acid (3), were isolated from the vines and leaves of Chonemorpha megacalyx Pierre. Their structures were established on the basis of extensive spectroscopic data.
