OBJECTIVETo investigate the chemical constituents of the branches and leaves of (Jvariu kurzii.
METHODCompounds were isolated and purified by silica gel and Sephadex LH-20 column chromatography. Their chemical structures were identified on the basis of physicoc hemical properties and spectral data.
RESULTNineteen compounds were isolated and identified as: beta-sitosterol hexadecanoate (1), stigmasterol hexadecanoate (2), beta-acetylsitosterol (3), beta-acetylstigmasterul (4), tetratriacontanol (5), dotriacontanoic acid (6), beta-sitosterol (7), stigmasterol (8), 5alpha-stigmast-3 , 6-dione (9) , 5alpha-stigmast-22-ene-3,6-dione (10), vanillic acid (11), protocatechuic acid (12), N-(p-trans-collmaroyl) tyramine (13). kaempferol-3-O-beta-D-(6"-O-p-coumaryoyl) galactopyraunoside (14), kaempferol-3-O-rutinoide (15), rutin (16), daucosterol (17), L-quebrachitol (18), allantoin (19), respectively.
CONCLUSIONCompounds 1-6, 9, 10, 13, 18, 19 were isolated from Annonaceac plants; Compounds 14-16 were obtained from the gemis Uvaria; an 7, 8, 11, 12, 17 were separated from this plant respectively for the first time.

OBJECTIVETo investigate the chemical constituents of the branches and leaves of Uvaria kurzii.
METHODThe 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.
RESULTNine 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).
CONCLUSIONCompound 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.
