摘要: 该文研究了从月光花叶中提取,并用高压液相色谱收集制备,命名为DC-2b化合物的一维及二维NMR谱.通过对它的一维,1H-NMR,13C-NMR宽带去偶,DEPT及选择性INEPT和二维1H-1H COSY,NOESY及13C-1H COSY等谱图的综合分析研究,确证了它的结构.

关键词: 月光花素甲, NMR, 结构

Abstract: Calonyctin A which was extracted from leaves of Calonyction aculeatum (L.) House was discovered being not a single component. We extracted the sample from Calonyction aculeatum (L.) House then separated by HPLC and got two major components denominated as DC-2b and DC-2d.
In this paper, the structure of DC-2b was determined by 13C-NMR, DEPT, SELECTIVE INEPT, 2D 1H-COSY, 2D 13C-1H COSY and 2D-NOESY techniques.

Key words: Calonyctin A, NMR, Structure
