STRUCTURES OF DAMMARANE-TYPE TRITERPENE TRIGLYCOSIDES FROM THE FLOWER BUDS OF PANAX GINSENG

摘要

New dammarane-type triterpene triglycosides,floralginsenosides G,H,I,J,K,La,and Lb,were isolated from the flower buds of Panax ginseng C.A.MEYER together with ten known dammarane-type triterpene oligoglycosides.The structures of new compounds were elucidated on the basis of chemical and physicochemical evidence.
