To investigate the chemical constituents of the branches and leaves of Uvaria kurzii.The compounds were isolated and purified by silica gel and Sephadex LH-20 column chromatographic methods. Their chemical structures were elucidated on the basis of physicochemical properties and spectral data.Nine compounds were isolated and identified as: bidebiline A(1), annobraine (2), oxoputerine (3), atherospermidine (4), liriodenine (5), physcion (6), questin (7), rubiadin 3-methyl ether (8), emodin (9).Compound 1-4, 6-9 were isolated from the genus Uvaria for the first time. Compound 3-5 showed inhabitation activities against tumor cell lines A549, Bel7402, BGC823, HCT-8, A2780, respectively.
