一系列1D ~1H和~（13）C NMR，DEPT实验）和2D NMR（包括gCOSY，gHSQC和gHMBC）技术对forbesoside [6′-O-[（trans-feruloyl）-tetrakenin]是从宽叶羌活（Notopterygium forbesii Boiss.）和羌活（Notopterygium incisum Ting ex H. T. Chang）的地下部分分离得到的一个新香豆素类化合物，具有抗从伞形花内酯到7-去甲基辛二醇、异甘草素、异甘草素和福贝苷，以及吡喃葡萄糖基的酰化羟甲基部分的NMR信号变化规律，并对糖的NMR信号归属方法进行了讨论和总结。
A series of 1D(~1H and()~(13)C 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.
