[Phenolic acid derivatives from the rhizome of Fagopyrum cymosum].
OBJECTIVE
To study the chemical constituents of Fagopyrum cymosum.


METHODS
The chemical constituents were isolated by various chromatographic methods and their structures were elucidated by the analysis of spectral data and physiochemical properties.


RESULTS
Four phenolic acid derivatives were isolated from F. cymosum. The chemical structures were elucidated as trans-p-hydroxy cinnamic methyl ester (I), 3, 4-dihydroxy benzamide (II), protocatechuic acid (III), protocatechuic acid methyl ester (IV).


CONCLUSIONS
Compounds I, II, IV were obtained from the genus Fagopyrum for the first time.
