The hexane extract of leaves of Erythroxylum passerinum yielded besides sitosterol, β-amyrin, lupeol and erythrodiol, β-amyrin palmitate, 3β,28-dihydroxy-olean-12-enyl palmitate, 3β,11β-dihydroxy-olean-12-enyl palmitate, 3β-hydroxy-11-oxo-olean-12-enyl palmitate and 3β-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).
