Abstract

Five new dammarane-type triterpene glycosides, floralquinquenosides A, B, C, D, and E, were isolated from the flower buds of American ginseng, Panax quinquefolium L., together with 18 known dammarane-type triterpene glycosides and 3 flavonoid glycosides. The structures of new floralquinquenosides were elucidated on the basis of chemical and physicochemical evidence.
