Abstract
Chemical investigation of the dichloromethane extracts of Wrightia pubescens (R.Br.) led to the isolation of ursolic acid (1), oleanolic acid (2), squalene (3), β-sitosterol (4) and chlorophyll a (5) from the leaves; and 1, 2 and α- amyrin acetate (6) from the twigs. The structures of 1-6 were identified by comparison of their 1HNMR and/or 13C NMR data with those reported in the literature.
