C－2，3，4，6，7－位含氧取代的9，10－二氢菲类化合物的NMR谱研究

THE STUDIES ON THE NMR SPECTRA OF 9,10 DIHYDROPHENANTHRENE WITH OXY SUBSTITUENTS AT C 2,3,4,6,7 POSITION

用２ＤＮＭＲ技术研究了获自朝鲜淫羊藿中的２—羟基—３，４，６，７—四甲氧基—９，１０—二氢菲的结构．对其碳氢信号进行了全归属．并对文献报道的同类化合物的碳信号归属进行了评述．

This paper deals with the studies of full assignments of 1H and 13C NMR chemical shifts of 2-hydroxy-3,4,6,7-tetramethoxy-9,10-dihydrophenanthrene isolated from Epimedium koreanum by means of 2D NMR spectroscopic analyses.The assignments of 13C NMR chemcial shifts of similar compounds published in literatures were reappraised.
