摘要：

In addition to eight known compounds [euchrenones a6, a11 and a12, glabrol, euchretins A-C, and lespedezaflavanone C], three new coumaronochromones were isolated from the roots of Euchresta japonica. By means of spectroscopic analysis, the structures of new compounds were characterized as 5,7,4',5'-tetrahydroxy-6,8-di(gamma,gamma-dimethylallyl)-, 5,4',5'-trihydroxy-6-gamma,gamma-dimethylallyl-[6'',6''-dimethylpyrano(2'',3'': 7,8)]-, and 5,7,5'-trihydroxy-8-gamma,gamma-dimethylallyl-[6''',6'''-dimethylpyrano(2'''3,3'''; 4',3')]-coumaronochromone, and were named cuchretins F, G and H, respectively.
