Objective:To investigate the chemical components of the leaves of Cyclocarya paliurus.Method: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.Result:Six compounds were isolated and identified as kaempferol(Ⅰ), quercetin(Ⅱ), isoquercitrin(Ⅲ), ellagic acid(Ⅳ), daucosterol(Ⅴ) and cyclocaric acid B(Ⅵ).Conclusion:Compounds Ⅰ,Ⅱ,Ⅲ and Ⅳ were obtained for the first time from this plant.
