| 摘 要： | 通过核磁共振对一个首次从菊科单种属植物-栌菊木中分离得到的乌药烷型倍半萜内酯-8β, 9-dihydro-onoseriolide进行了结构解析，通过2D NMR (HSQC，HMBC，NOESY )首次对该化合物的碳和氢质子信号进行全归属；并证实其结构中的 H-1，H-2 互为颠倒，纠正了文献报道中的错误，该研究对乌药烷骨架倍半萜内酯的结构鉴定提供了光谱学依据.

| 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. |
