title: 3 beta-hydroxy-28-P-coumaroyloxy-lup-20(29)-en-27-oic acid from Caraipa densifolia.
abstract: Caraipa densifolia Mart. (Clusiaceae) has afforded the new lupene derivative 3 beta-hydroxy-28-p-coumarolyoxy-lup-20(29)-en-27-oic acid (8), whose structure was deduced by chemical correlation with betulin (6). Simiarenol (1), taraxerone (2), friedelin (3), lupeol (4), betulinic acid (5), betulin (6), and beta-sitosterol-beta-D-glucoside (7) were also isolated in this study.
