苯并二氢呋喃类木脂素NMR谱的研究

THE STUDIES ON THE NMR SPECTRA OF DIHYDROBENZOFURAN LIGNANS

用2DHMR技术研究了从水飞蓟素（Silymarin）中分离的一个苯并二氢呋喃类木脂素的结构，证实该类化合物的取代基位置可用COLOC谱确定．同时研究了该类化合物以DMSO-d6为溶剂的PMR谱的特征．另外对Balanophonin的PMR谱进行了详细归属．

The chemical structure of dihydrobenzofuran lignans Balanophonin(1) was studied by 2D NMR spectra analyses. It was observed that the attached position of methoxyl and hydroxyl groups in A ring can be determined by analysing the cross peaks in COLOC spectrum. Meanwhile, the speciality of PMR spectra (in DMSO-d6) of this kind of compounds was studied. All the proton signals of Balanophonin (1) were assigned in detail also.
