Abstract
Subject headings
Close
- Crude petroleum ether extract from the bark of Poulsenia armata showed antimicrobial activity. Activity-guided fractionation led to the isolation and structure elucidation of two active new triterpene derivatives, the stearate of glut-5-en-3beta-ol (1) and 3beta,28-diacetoxyurs-12-ene (4), for the first time as naturally occurring compounds. Compound 4 has previously been synthesized. The structures were determined by 1D- and 2D-NMR spectroscopy, mass spectrometry and chemical transformations. This is the first report on the chemistry and pharmacology of the genus.
