西洋参果中配糖体成分的研究

Studies on the Glycosides from American Ginseng Fruit (Panax quinquefolium)

从西洋参果中分得 ６个配糖体。经理化常数和波谱分析分别鉴定为人参皂苷 ２０（Ｓ）－Ｒｇ_３（Ⅰ）、２０（Ｒ）－Ｒｇ３（Ⅱ）、－Ｒｅ（Ⅲ）、－Ｒｄ（Ⅳ）、－Ｒｂ３（Ⅴ）和胡萝卜苷（Ⅵ）。化合物Ⅰ～Ⅵ均为首次从该植物分得的已知化合物。

Six glycosides were isolated from the fruit of Panax quinquefolium L.. They were identified as 20 (S)-Rg3(Ⅰ ), 20 (R)-Rg3(Ⅱ ), -Re (Ⅲ ), -Rd (Ⅳ ), -Rb3(Ⅴ ) and daucosterol (Ⅵ ) respectively, on the basis of chemical evidences and spectral analysis. All the glycosides were separated from the fruit of P. quinquefolium L. for the first time.
