摘要
Abstract
A sesquiterpene lactone was isolated from Nouelia insignis Franch,and its structure was elucidated(compound 1)by 2D NMR to be 8β,9-dihydro-onoseriolide.Complete assignment of the 1H and 13C chemical shifts for the compound was obtained.The assignments of H1 and H-2 of the compound previously reported were found incorrect,and the correct assignments were given.The results of this study may have some practical significance for the structural elucidation of onoseriolide sesquiterpene lactones.关键词
