title: A Novel Tirucallane-type Triterpene and Sesquiterpene from Trichilia maynasiana.
abstract: One new tirucallane-type triterpene {3β, 24-dihydroxytirucallan-7,25-diene, 24-sulfate (1)}, one new sesquiterpene {7-epi-10-hydroxychabrol-1(2)-en-4,5-dione A (2)}, together with three known tirucallanes, and four aromadendranes were isolated from the leaves of Trichilia maynasiana C. DC.. Their structures were determined by means of NMR spectroscopy, mass spectrometric analysis, and chemical methods.
