Abstract
From the petroleum ether extract of the roots of Carissa spinarum Linn. (Apocynaceae), six compounds namely stigmasterol, ursolic acid, lupeol, campesterol, 17-hydroxy-11-oxo-nor-β-amyrone and urs-12-ene-3β, 22β-diol17-carboxylic acid have been isolated by column chromatography. Their structures were characterized by m.p., IR, 1 HNMR, 13 CNMR and mass spectral data. However, the compounds stigmasterol, campesterol, 17-hydroxy11-oxo-nor-β-amyrone and urs-12-ene-3β, 22β-diol-17-carboxylic acid were reported for the fi rst time from the root of this plant.
