ABSTRACT
<p><b>OBJECTIVE</b>To investigate the chemical constituents of the branches and leaves of Uvaria kurzii.</p><p><b>METHOD</b>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.</p><p><b>RESULT</b>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).</p><p><b>CONCLUSION</b>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.</p>

<p><b>OBJECTIVE</b>To investigate the chemical constituents of the branches and leaves of (Jvariu kurzii.</p><p><b>METHOD</b>Compounds 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.</p><p><b>RESULT</b>Nineteen 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.</p><p><b>CONCLUSION</b>Compounds 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.</p>
