Studies on the chemical constituents in the leaves of Cyclocarya paliurus / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the chemical components of the leaves of Cyclocarya paliurus.</p><p><b>METHOD</b>The chemical components were isolated by solvent extraction and column chromatography. The chemical structures were identified on the basis of physic-chemical constant and spectral data.</p><p><b>RESULT</b>Six compounds were isolated and identified as kaempferol(I), quercetin(II), isoquercitrin(III), ellagic acid(IV), daucosterol(V) and cyclocaric acid B(VI).</p><p><b>CONCLUSION</b>Compounds I, II, III and IV were obtained for the first time from this plant.</p>
