Fatty Acid Esters of Triterpenes from Erythroxylum passerinum

Abstract

The hexane extract of leaves of Erythroxylum passerinum yielded besides sitosterol, beta-amyrin, lupeol and erythrodiol, beta-amyrin palmitate, 3beta,28-dihydroxy-olean-12-enyl palmitate, 3beta,11beta-dihydroxy-olean-12-enyl palmitate, 3beta-hydroxy-11-oxo-olean-12-enyl palmitate and 3beta-hydroxy-11,12-epoxy-friedoolean-14-enyl palmitate. The structural elucidation of the isolates and of their derivatives were based on spectral data (¹H and 13C NMR, IR and MS).
