Abstract:
Two new secodammarane triterpenoid saponins, cyclocariosides I and J (1 and 2), and a new epoxydammarane triterpenoid saponin, cyclocarioside K (3) were isolated from the ethanol extracts of the leaves of Cyclocarya paliurus. The structures of these compounds were elucidated by spectroscopic techniques.
