Abstract: 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.

Key words: dihydrophenanthrene with oxy-substituents at C-2,3,4,6,7 position, NMR assignemts of 13C NMR chemical shifts
