Abstract
Two triterpenoid saponine were isolated from the stems of Acer ginnala Maxim. The structures of triterpenoid saponins were established as ilexoside O, $3-O-{\alpha}-L- rhamnopyranosyl(1{\rightarrow}2)-{\beta}-D-glucopyranosyl(1{\rightarrow}2)-{\beta}-D-xylopyranosyl-pubescenolic$ acid 28-{\beta}-D-glucopyranosyl$ ester(1) and ilexoside K, $3-O-{\beta}-D-glucopyranosyl(1{\rightarrow}2)-{\beta}-D-xylopyranosyl-pubes-cenolic$ acid $28-{\beta}-D-glucopyranosyl$ ester(2). Their chemical structures have been elucidated on the basis of spectral methods.
