大果阿魏酮化学结构的研究

Astudy on chemical structure of lehmannolone

采用二维核磁共振技术，并借助一维技术ＤＥＰＴ（无畸变极化转移实验）对新倍半萜香豆素大果阿魏酮（ｌｅｈｍａｎｎｏｌｏｎｅ）的全部￣１Ｈ－ＮＭＲ和￣（１３）Ｃ－ＮＭＲ信号进行归属。应用Ｘ－衍射测定了其结构。

wo dimensional NMR techniques(￣1H-￣1HCOSY,HEYCOH,LRHETC with the assistanceof one dimensional NMR(￣1 H-NMR,￣(13)C-DEPT)have been used to assign ￣1H and￣(13)C resonnances in a new sesquiterpenoid coumarin,lehmannolone and established its structure by X-ray diffraction method.
