<p><b>OBJECTIVE</b>To study the alkaloids in the stems and leaves of Stephania cepharantha.</p><p><b>METHOD</b>The dried stems and leaves of S. cepharantha were percolated with 95% ethanol and the solvent was removed by rotary evaporation to give a concentrate, and the concentrate was extracted by petroleum ether and chloroform. Column chromatograghy on MCI CHP 20P, silica gel, Rp-18, Sephadex LH-20 and polyamide were applied for the isolation and purification of the chloroform fraction. The structures were elucidated by their physicochemical properties and spectral data.</p><p><b>RESULT</b>Eleven alkaloids were obtained and identified as lysicamine (1), tetrahadropalmatine (2), palmatine (3), isocorydione (4), corydalmine (5), corypalmine (6), sinoracutine (7), sinoacutine (8), cepharamine (9), isocorydine (10) and corydine (11).</p><p><b>CONCLUSION</b>Compounds 2-7 were isolated from S. cepharantha for the first time, and compound 7 was isolated from the genus Stephania for the first time, compound 4 was isolated from the Menispermaceae family for the first time.</p>
