报道了10个5，7-二羟基黄酮类化合物的核磁共振研究，通过H-1-C-13HETCOR和COLOC(或HMBC)实验的详细光谱分析，得到了质子和碳信号的完整归属。重新归属了(+)-儿茶素、(-)-表儿茶素、二氢栎素和二氢杨梅素的H-6和H-8的质子信号。
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.
