Abstract: The total ginsenoside extract of Panax quinquefolium  was hydrolyzed by β-glycosidase.HPLC analysis indicated that ginsenosides Rb1,Rd,Rc and Rb2 were completely hydrolyzed.Seven ginsenosides were isolated from the hydrolysate,and identified as ginsenoside compound K (1),ginsenoside Mc (2),ginsenoside Rg1 (3),ginsenoside Rg2 (4),ginsenoside Re (5),ginsenoside F1 (6) and pseudoginsenoside F11 (7),respectively.The protopanaxdiol type ginsenosides in the total ginsenoside extract of P.quinquefolium were converted into ginsenoside compound K and ginsenoside Mc by the β-glycosidase.

Key words: Panax quinquefolium, protopanaxdiol type ginsenosides, ginsenoside compound K, β-glycosidase
