中文摘要：

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F1（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。

英文摘要：

The total ginsenoside was extracted from the stems and leaves of Panax ginseng and then hydrolyzed withβ- glyeosidase. Eight compounds were isolated from the hydrolysate, and identified as 20 （S） -dammarane-3β, 6a, 128,20, 25-pentol （ 1 ）, ginsenoside compound K（ 2 ） , ginsenoside Fl （ 3 ） , ginsenoside Rh13 （4）, ginsenoside Rg2 （ 5 ） ,313,20 （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 protopunaxadioltype ginsenoside, suggesting that the protopanaxadiol-type ginsenosides in the total extract from the stems and leaves of P. ginseng was converted into ginseneside compound K by β-glyeosidase.
