[Chemical constituents of Uvaria kurzii].
OBJECTIVE
To investigate the chemical constituents of the branches and leaves of (Jvariu kurzii.


METHODS
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.


RESULTS
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.


CONCLUSIONS
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.
