摘要：

Seven new isoflavones, named euchrenones b10 b10 were isolated from the roots of Euchresta japonica. By means of spectral data, the inuctures were determined to be 5,5'-dihydroxy-2'-methoxy-8-gamma,gamma-dimethylally-[6'',6''-dimethylpyrano(2'',3'':7,6)]-[6'''',6''''-dimethylpyrano(2'''',3'''':4'3')]-, 5,5'-dihydroxy-2'methoxy-6-gamma,gamma-dimethylallyl-[6'',6''-dimethylpyrano(2'',3'':7,8)]-[6'''',6''''-dimethylpyrano-(2'''',3'''':4',3')]-, 5,4'-dihydroxy-2'-methoxy-8,3'-di(gamma,gamma-dimethylallyl)-[6'',6''-dimethylpyrano(2'',3'':7,6)]-, 5,4'-dihydroxy-2'-methoxy-6,3'-di(gamma,gamma-dimethylally)-6'',6''-dimethylpyrano(2'',3'':7,8)]-, 5,7,4'-trihydroxy-2'-methoxy-6,8,3-tri-(gamma,gamma-dimethylallyl)-, 5,7,4'-trihydroxy-2'-methoxy-6,8-di(gamma,gamma-dimethylally)- and 5,2',4'-trihydroxy-6,3'-di(gamma,gamma-dimethylallyl)-[6'',6''-dimethylpyrano(2'',3'':7,8)]isoflavone, respectively.
