Abstract: One previously undescribed triterpene glycoside ( 1 ) and two known compounds were isolated from the leaves of Cyclocarya paliurus ( 2-3 ). Their structures were elucidated based on methods of spectroscopic analysis and NMR data comparison with those in the literature. Compound 1 showed a moderate inhibitory effect on melanogenesis with an IC <subscript>50</subscript> value of 282.3 μM, with the positive drug arbutin showing an IC <subscript>50</subscript> value of 168.5 μM.
