摘要: 从传统中药羌活中分离得到1个香豆素类化合物,应用1D和脉冲梯度场反相2D NMR检测技术 (gCOSY, gNOESY, gHMQC, gHMBC) 研究了其结构,鉴定为6′-O-(反式阿魏酰基)-紫花前胡苷,命名为羌活苷(Forbesoside). 本文对其碳氢NMR信号进行了全归属. 对从伞形花内酯衍生化为7-去甲基软木花椒素、紫花前胡苷元和6′-O-(反式阿魏酰基)-紫花前胡苷的NMR信号变化规律以及糖残基NMR信号归属方法进行了讨论和总结.

Abstract: A series of 1D (1H and 13C NMR, DEPT experiment) and 2D NMR (including gCOSY, gHSQC and gHMBC) techniques were applied to the assignment of all proton and carbon signals of forbesoside [6′-O-(trans-feruloyl)-nodakenin] which was a new coumarins compound isolated from the underground parts of Notopterygium forbesii Boiss. and Notopterygium incisum Ting ex H. T. Chang and with anti-inflammatory bioactivity. The NMR signals changed rules from umbelliferone to 7-demethylsuberosin, nodakenetin, nodakenin and forbesoside, and of acyled hydroxymethyl moiety of glucopyranosyl group, and methods of NMR signals assignment of saccharide were discussed and summarized.

Key words: NMR, forbesoside, 6′-O-(trans-feruloyl)-nodakenin, umbelliferone, nodakenetin, Notopterygium forbesii and Notopterygium incisum
