Phytochemical screening of Caralluma lasiantha was carried out and one C 21 pregnane steroid was isolated from chloroform extract. Based on spectroscopic studies (IR, 1 H NMR, 13 C NMR and ESI-MS) the isolated compound is 3b,14b-dihydroxy-14b-pregn-5-en-20-one which was earlier isolated from other species.
