摘要
报道对生姜(Zingiber officinale)中分离得到的活性成分姜酮(1),通过二维核磁共振谱(1H-1H CO-SY、HSQC、HMBC)完全解析1H NMR、13C NMR信号的结果.修订其13C NMR谱信号归属,并确证了姜酮(1)的化学结构.还讨论了不同溶剂(氘代甲醇、氘代氯仿、DMSO)对姜酮(1)侧链上相邻亚甲基质子,一个典型—A2B2—系统质子信号的影响,是溶剂对姜酮中质子偶合影响,对姜酮衍生物类的生物活性研究起重要作用.
In this paper, the chemical structure Zingiber officinale was conformed and the 13C NMR of zingiberone （ 1 ）, which a common compound isolated from signals of zingiberone （ 1 ） were assigned first time by 1 D and 2D NMR techniques （^1H- ^1H COSY,HSQC and HMBC）. This paper described that IH NMR signal figures of the protons of adjacent two methylene which should be a typical A2B2 system in zingiberone （ 1 ） were affected by different deuterated solvent, and probably reasons were also discussed.
