Oleanene Glycosides from the Leaves of Acanthopanax seiboldianus forma albeofolium Yook

Four known oleanane glycosides were isolated for the first time from the MeOH extract of the leaves of Acanthopanax sieboldianus forma albeofolium Yook by using column chromatography.They were identified as kalopanax-saponin B (1),acanthopanax saponin CP3 (2),kalopanax-saponin A (3) and sieboldianoside A (4) on the basis of physicochemical and spectroscopic data (1H NMR,13C NMR,2D NMR and FAB-MS).
