珠子参的化学成分

目的对珠子参[PanaxjaponicusC.A.Mey.var.major(Buck.)C.Y.Wu et K.M.Feng]根茎的化学成分进行研究。方法采用硅胶柱色谱进行分离纯化,根据理化性质和波谱数据进行结构鉴定。结果分离得到8个化合物,分别鉴定为苯甲酸(benzoin acid,1)、豆甾醇(stigmasterol,2)、齐墩果酸(oleanolic acid,3)、胡萝卜苷(daucosterol,4)、齐墩果酸-28-O-β-D-吡喃葡萄糖苷(oleanolicacid-28-O-β-D-glucopyranoside,5)、齐墩果酸-3-O-β-D-吡喃葡萄糖基(1→2)-β-D-(6′-丁酯)吡喃葡萄糖醛酸苷(oleanolic acid-3-O-β-D-glucopyranoside(1→2)-β-D-glucorunopyranosy-6′-O-butylester,6)、竹节参皂苷IVa(chikusetsusaponinⅣa,7)、人参皂苷Ro(ginsenoside,8)。结论化合物6为新化合物,化合物1、2为首次从该种植物中分离得到。

Chemical constituents of rhizome of Panacis Majoris

Objective To study the chemical constituents of Panacis Majoris（rhizome of [Panax japonicus C.A.Mey.var.major(Buck.)C.Y.Wu et K.M.Feng]）. Methods The Chemical constituents were isolated by various column chromatographic methods, and the structures of these compounds were identified by MS,¹H-NMR,¹³C-NMR spectral analysis. Results Eight compounds were isolated and elucidated as: benzoic acid（1）,stigmasterol(2),oleanolic acid(3),daucosterol(4),oleanolic acid-28-O-β-D-glucopyranoside(5),oleanolic acid-3-O-β-D-glucopyranoside(1→2)- β-D-glucorunopyranosy-6’-O-bustyl ester(6),chikusetsusaponin IVa(7), ginsenoside Ro(8), respectively. Conclusion Compound 6 is obtained for the first time and compounds 1 and 2 are obtained from this plant for the first time.
