Triterpenes and sterol from Artocarpus ovatus

Abstract

Chemical investigation of the dichloromethane extract of the twigs of Artocarpus ovatus afforded lupeol (1a), α-amyrin (1b), β-amyrin (1c), lupeol fatty acid ester (2a), α-amyrin fatty acid ester (2b), β-myrin fatty acid ester (2c), betulin (3a), 3β, 28-Dihydroxyolean-12-ene (3b), oleanolic acid (4), β-sitosterol (5), and chlorophyll a (6). The structures of 1-6 were identified by comparison of their 1H and/or 13C NMR data with those reported in the literature.
