Phenolic acid derivatives from the rhizome of Fagopyrum cymosum / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the chemical constituents of Fagopyrum cymosum.</p><p><b>METHOD</b>The chemical constituents were isolated by various chromatographic methods and their structures were elucidated by the analysis of spectral data and physiochemical properties.</p><p><b>RESULT</b>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).</p><p><b>CONCLUSION</b>Compounds I, II, IV were obtained from the genus Fagopyrum for the first time.</p>
