摘    要:从三七(Panax notoginseng)要总皂甙的弱酸水解产物中分离得到三个原人参二醇型单糖链配糖体。通过光谱方法,鉴定其结构分别为人参皂甙Rg5,20(R)-人参皂甙-Rg3与20(S)-人参皂甙Rg3。应用2D NMR技术,对它们的^1H和^13C化学位移进行了全归属。

关 键 词:三七  原人参二醇型单糖链配糖体  NMR信号全归属

Abstract:Three protopanaxodiol monodesmosides isolated from mild acid hydrolysis products of root saponins of \%Panax notoginseng\% were identified as ginsenoside Rg5, 20(R) ginsenoside Rg3 and 20(S) ginsenoside Rg3. The complete assignments of 1H and \{\} 13 C NMR chemical shifts of these glycosides were obtained by means of 2D NMR techniques, such as 1H 1H COSY, TOCSY, ROESY, HMBC as well as HMQC. The differences of chemical shifts of 20(R) and 20(S) isomer were discussed.
Keywords:Panax notoginseng  Protopanaxodiol saponins  NMR complete assignments
