[Studies on chemical constituents of Cercis chinensis].
OBJECTIVE
To study the chemical constituents from the aerial part of Cercis chinensis.


METHODS
The constituents of C. chinensis were separated with various chromatographic techniques and their structures were elucidated by means of spectral analysis and physico-chemical properties.


RESULTS
Nine compounds were isolated from C. chinensis. They were identified as 3-O-methylquercetin (1), quercetin (2), (2R,3R)-3, 5, 7, 3', 5'-pentahydroxyflavan (3), 3', 5, 5', 7-tetrahydroxyflavanone (4), [+]-taxifolin (5), (2R)-naringenin (6), friedelin (7), beta-sitosterol (8), daucosterin (9).


CONCLUSIONS
compounds 1 and 3-7 were isolated from the genus Cercis for the first time.
