摘要: 西洋参总皂苷经β-糖苷酶催化水解,采用HPLC检测分析确定西洋参总皂苷中的主要原人参二醇型皂苷Rb1、Rd、Rc和Rb2已经完全被水解。水解产物通过反复硅胶柱层析和反向硅胶柱层析分离纯化得到7个皂苷,通过NMR谱图分析分别鉴定为人参皂苷compound K(1)、人参皂苷Mc(2)、人参皂苷Rg1(3)、人参皂苷Rg2(4)、人参皂苷Re(5)、人参皂苷F1(6)和拟人参皂苷F11(7)。β-糖苷酶催化西洋参总皂苷水解实验表明,西洋参中原人参二醇型皂苷的水解产物是人参皂苷compound K和人参皂苷Mc。

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
