摘要：In our search for biologically active compounds, three steroids have been isolated from the stem bark of Parinari curatellifolia through series of column chromatography . Compound C 1 , C 2 and C 3 where characterized as ?-sitosterol (22,23-dihydrostigmasterol), stigmast-4-en-3-one and stigmasterol, respectively, on the basis of 1D-NMR ( 1 HNMR, 13 CNMR and DEPT-135), 2D-NMR (HSQC, HMBC, 1 H- 1 H COSY, 1 H- 1 H NOESY), mass spectroscopy (MS) and IR spectroscopy. These compounds are reported for the first time as constituents in Parinari curatellifolia.
