Abstract

Six new triterpenoids including four new secodammarane triterpenoid glycosides (1-4), an epoxydammarane triterpenoid glycoside (5), and a new secodammarane triterpenoid (6) were isolated from the ethanolic extract of the leaves of Cyclocarya paliurus. The structures of these compounds were elucidated by spectroscopic analysis methods. Compounds 1-6 were evaluated for their inhibitory activities against α-glucosidase, Lipase, DPP-IV, and Aldose Reductase.
