From the stem of Diospyros rubra Lec., three triterpeniods including lupeol, betulin and ursolic acid, together with a mixture of beta-sitosterol and stigmasterol, have been isolated. Identification of these compounds was accomplished by analysis of IR, MS, [superscript 1]H-NMR and [superscript 13]C-NMR data, as well as the comparison with reported values.
