摘要/Abstract

摘要： 用2D NMR(¹H-¹H COSY,¹H-¹³C COSY,HMBC)技术研究了从尾叶远志中分离得到的一个苯甲酰基取代(口山)酮甙的结构,并对其碳氢信号进行了全归属.

关键词: 苯甲酰基取代(口山)酮甙, 碳氢信号全归属

Abstract: This paper deals with the chemical structure of a benzoyl-substituted xanthone-C-glycoside isolated from the roots of Polygala caudata (Polygalacese)studied by means of NMR spectral analysis.With the aid of 2D NMR techniques (including ¹H-¹H COSY, ¹H-13 CCOSY and HMBC), the full assignments of ¹H and ¹³C NMR spectral data were presented.

Key words: Benzoyl-substituted xanthone-C-glycoside, Full assignments of ¹H and ¹³C NMR spectral data, HMBC
