摘要: 人参茎叶提取物经β-糖苷酶催化水解后,经硅胶柱和RP-18柱反复层析纯化得8个化合物。通过波谱图分析及结合文献数据,分别鉴定为20(S)-达玛烷-3β,6α,12β,20,25-五醇(1)、人参皂苷compound K(2)、人参皂苷F1(3)、人参皂苷Rh13(4)、人参皂苷Rg2(5)、3β,20(S)-二羟基达玛烷-24-烯12β,23β-环氧-20-O-β-D-吡喃葡萄糖苷(6)、人参皂苷Rg1(7)和人参皂苷Re(8)。其中化合物1为新的达玛烷皂苷元。化合物2为分离到仅有的原人参二醇型皂苷,表明该β-糖苷酶高效转化人参茎叶的原人参二醇型皂苷为人参皂苷compound K。

Abstract: The total ginsenoside was extracted from the stems and leaves of Panax ginseng and then hydrolyzed with β-glycosidase.Eight compounds were isolated from the hydrolysate,and identified as 20(S)-dammarane-3β,6α,12β,20,25-pentol(1),ginsenoside compound K(2),ginsenoside F1(3),ginsenoside Rh13 (4), ginsenoside Rg2(5),3β,20(S)-dihydroxydammar-24-en-12β,23β-epoxy-20-O-β-D-glucopyranoside(6),ginsenoside Rg1(7) and ginsenoside Re(8), respectively. Among them,compound 1 is an unknown dammarane sapogenin.Compound 2 was the only protopanaxadiol-type ginsenoside,suggesting that the protopanaxadiol-type ginsenosides in the total extract from the stems and leaves of P.ginseng was converted into ginsenoside compound K by β-glycosidase.

Key words: stems and leaves of Panax ginseng, β-glycosidase;protopanaxadiol-type ginsenoside;ginsenoside compound K
