Abstract

The methanol extract of leaves and bark of Stereospermum suaveolens has been subjected to repeated-chromatographic separation and purification processes to isolate the secondary metabolites. A total of seven compounds have been isolated from the plant, which were identified as fridelin (1), β-sitosterone (stigmast-5- en-3-one) (2), stigmasterol (3), 3,4-dimethoxy cis-caffeic acid (4), 3β-friedelanol (5), β-amyrone (6) and glyceryl tricaprate (7). The structures of the isolated compounds were elucidated by extensive NMR studies.
