14 alkaloids were obtained from stems and leaves of Fissistigma oldhamii, by silica gel, ODS, Sephadex LH-20 column chromatographies, and semi-preparative HPLC. Using physicochemical and spectral methods, the isolated alkaloids were identified as norcepharadione B(1), asimilobine(2), lanuginosine(3), laurotanine(4), isocorydine(5), anolobine(6), xylopine(7), N-methylbuxifoline(8), aristolactam AIIIa(9), piperumbellactam A(10), goniopedaline(11), aristololactam BIII(12), liriodenine(13), and salutaridine(14), respectively. Compounds 3-5, 8, 10, 11 and 14 were isolated from the genus Fissistigma for the first time.
