Abstract
OBJECTIVE: To study the chemical constituents from the aerial part of Cercis chinensis. METHOD: 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. RESULT: 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). CONCLUSION: compounds 1 and 3-7 were isolated from the genus Cercis for the first time.
