Secondary Metabolites From Different Extractives of Stereospermum suaveolens

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
