Abstract
Two triterpine acids like 2 alpha, 19 alpha- dihydroxy - 3-oxo-12-ursen-28-oic acid (1), 2 alpha, 16 alpha, 19 alpha- trihydroxy - 3-oxo-12-ursen-28-oic acid (2) were isolated from the n-hexane soluble fractions of a methanol extract of the root of Albizzia lebbeck Benth. The structures of the isolated compounds were elucidated as by extensive spectroscopic studies, including high field NMR analyses. This is the first report of isolation of compounds 1-2 from this species.
