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.
