Abstract

Five new saponins, ilexosides XX-XXIV, were isolated from the fresh bark of Ilex crenate, and their structures were elucidated on the basis of chemical and physicochemical evidence. Ilexoside XX is the 3, 28-bisdesmoside of siaresinolic acid, whereas ilexosides XXI-XXIV are those of 3β, 19α, 21α-trihydroxyurs-12-en-28-oic acid.
