摘要
借助2DNMR技术，研究并总结了10个含异戊烯类取代基的黄酮化合物的(13)CNMR谱，着重就取代基与黄酮骨架的连接点进行了探讨，认为C-8位和C-5’位异戊烯类取代基取代将直接影响C-8和C-5’位及周围碳的化学位移值。
(13)C NMR spectra of 10 prenoid-subtituted flavonoids, which were obtained from the faultly Berberidaceae have been studied by means of 2D NMR (1H- 1H COSY, 1H- (13)C COSY and HMBC) technique on the basis of key compound. The discussion is mainly focused on the linkage between the isoprenoid- substitucnts with flavonoids skeletons and the relation between the chemical shifts and mode of isoprenoid-substituents at C-8 and C-5' positions. The result can be used to elucidate the structure of isoprenoid-substituted flavonoids.
