摘要
用NMR数据解析方法对8-异戊烯基黄酮醇苷类化合物朝藿定C(Epimedin C)的结构进行研究.联合应用一维NMR(1H NMR\13CNMR\DEPT)和二维NMR(1H-1HCOSY\HSQC\HMBC)技术对朝藿定C进行归属指认.朝藿定C所有的1H和13C NMR数据(包括异戊烯基和糖单元),得到了详细解析和全归属,其结构得到了进一步确证.为该类化合物异戊烯基和糖单元的结构鉴定提供了可靠的解析方法.
Epimedin C, a 8-isopentene flavonol glycoside isolated from Epimedium speices, was detected through 1D （1H,13C NMR and DEPT） and 2D NMR （1_H-1H COSY,HSQC, and HMBC） techniques. Final- ly, its 1H and 13C NMR spectra were completely analyzed and assigned and its structure was further identified. This research provided NMR data analysis method and evidences for the identification of 8-isopentene flavonol glycosides, especially the isopentene group and glucose units.
