摘要：

The NMR studies of 10 5,7-dihydroxyflavonoids are reported and the complete assignment of proton and carbon signals is obtained by detailed spectral analysis of H-1-C-13 HETCOR and COLOC (or HMBC) experiments. The proton signals of H-6 and H-8 of (+)-catechin, (-)-epicatechin, dihydroquercetin and dihydromyricetin were reassigned.
