Abstract

Six new saponins, ilexosides XLVI-LI, were isolated from fresh leaves of Ilex rotunda, and their structures were elucidated on the basis of chemical and physicochemical evidence. Ilexosides XLVI, XLVII, L and LI are 3, 28-bisglycosides of ilexosapogenin A, spathodic acid, bredemolic acid, and siaresinokic acid, respectively. Ilexosides XLVIII and XLIX are 3, 28-bisglycosides of hederagenin.
