Abstract:In order to understand the chemical constituents of Cyclocarya paliurus, twelve compounds were isolated from the 95% ethanol extract of its leaves. On the basis of spectral data, they were identified as zingerone (1), caffeic acid methyl ester (2), naringenin (3), arjunolic acid (4), 1-oxo-3β,23-dihydroxyolean-12-en-28-oic acid (5), 2α-hydroxyursolic acid (6), kaempferol (7), quercetin (8), kaempferol-3-O-(3-O-acetyl-α-l-rhamnopyranoside) (9), luteolin (10), 1-oxo-3β,23-dihydroxyolean-12-en-28-oic acid 28-O-β-d-glucopyranoside (11) and afzelin (12). Compounds 1, 2, 5, 9 and 11 were obtained from this plant species for the first time.
