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, 12β, 20(S), 24ξ, 25-五羟基达玛-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-F₁(Ⅴ)。同时鉴定了4种已知达玛烷型三萜皂苷, 即人参皂苷-Rh₁(Ⅵ)、人参皂苷-Rh₂(Ⅶ)、人参皂苷-Rg₁(Ⅷ)及人参皂苷-Rg₂(Ⅸ), 均为首次从该植物果实中分离得到。

A new triterpenoid saponin, quinquenoside F₁(Ⅴ) was isolated from the fruit of Panax quinquefolius L collected in Canada. Its structure was established as 3β, 12β, 20(S), 24ξ, 25 pentahydroxy dammarane 3Oβ 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 Rh₁(Ⅵ), Rh₁(Ⅶ), Rg₁(Ⅷ) and Rg₂(Ⅸ). All of them were obtained from the fruit of this plant for the first time.
