Abstract

Five new saponins, ilexosides XV-XIX, were isolated from the fresh bark of Ilex crenata, and their structures were elucidated on the basis of chemical and physicochemical evidence. Ilexosides XV-XVII are 3, 28-bisdesmosides of siaresinolic acid, whereas ilexosides XVIII and XIX are those of pomolic acid.
