西洋参果皂苷成分的研究

Saponins from the Fruit of Panax quinquefolius Collected in Canada

从加拿大产西洋参果中分得一种达玛烷型新三萜皂苷 ,利用理化性质和波谱数据鉴定为 3β,12 β,2 0 (S) ,2 4ξ,2 5 -五羟基达玛 - 3- O- β- D-吡喃葡萄糖基 - (1→ 2 ) - β- D-吡喃葡萄糖苷 ,命名为西洋参皂苷 - F1 ( )。同时鉴定了 4种已知达玛烷型三萜皂苷 ,即人参皂苷 - Rh1 ( )、人参皂苷 - Rh2 ( )、人参皂苷 - Rg1 ( )及人参皂苷 - Rg2 ( ) ,均为首次从该植物果实中分离得到。

A new triterpenoid saponin, quinquenoside F 1(Ⅴ) was isolated from the fruit of Panax quinquefolius L collected in Canada. Its structure was established as 3 β, 12 β, 20 (S), 24 ξ, 25 pentahydroxy dammarane 3 O β D glucopyranosyl (1→2) β D glucopyranoside, on the basis of chemical and spectroscopic evidences 4 known dammarane triterpenoids were also identified at the same time, i. e. ginsenoside Rh 1 (Ⅵ), Rh 2 (Ⅶ), Rg 1 (Ⅷ) and Rg 2 (Ⅸ). All of them were obtained from the fruit of this plant for the first time.
