Objective To study the chemical constituents isolated from the leaves of Cyclocarya paliurus. Methods The chemical constituents from the leaves of C. paliurus were isolated and purified by chromatography on silica gel and Sephadex LH-20 columns. Their structures were identified on the basis of spectroscopic data and physicochemical properties. Results Twelve compounds were isolated and identified as pterocaryoside B (1), cyclocaric acid B (2), 2α-hydroxyursolic acid (3), arjunolic acid (4), ursolic acid (5), oleanolic acid (6), taraxerol (7), 6, 9-dihydroxy-7-megastigmen-3-one (8), loliolide (9), kaempferol-3-O-α-L-rhamnopyranoside (10), behenic acid 1-propanetriol ester (11), and β-sitosterol (12). Conclusion Compounds 7—10 are isolated from the plants in Cyclocarya Iljinskaja for the first time.
