摘要：

Five new flavonoid compounds and a new benzofuran were isolated from the roots of Euchresta tubulosa in addition to eight known compounds [euchrenones a1, a4 and b2 and euchretins A-E]. The structures of the new compounds were characterized as 8-gamma,gamma-dimethylallyl-5-hydroxy-{6'',6''-dimethylpyrano(2'',3'':7,6)}-{6'''',6''''-di-methylpyrano(2'''',3'''':4',3')} flavanone (euchrenone a14), 6-gamma,gamma-dimethylallyl-5-hydroxy-{6'',6''-dimethylpyrano-(2'',3'':7,8)}-{6'''',6''''-dimethylpyrano(2'''',3'''':4',3')}flavanone (euchrenone a15), 8-gamma,gamma-dimethylallyl-5,2'-dihydroxy-{6'',6''-dimethylpyrano(2'',3'':7,6)}-(6'''',6''''-dimethylpyrano(2'''',3'''':4',3')}isoflavone (euchrenone b18), 6-gamma,gamma-dimethyl-allyl-5,2'-dihydroxy-16'',6''-dimethylpyrano(2'',3'':7,8)}-{6'''',6''''-dimethylpyrano(2'''',3'''':4',3')}isoflavone (euchrenone b17), 6,3'-di(gamma,gamma-dimethylallyl)-5,4',5'-trihydroxy-{6'',6''-dimethylpyrano(2'',3'':7,8)}coumaronochromone (euchretin I) and 2-[{6'',6''-dimethylpyrano(2'',3'':2',3')}-{6''',6'''-dimethylpyrano(2''',3'':4',5')}phenyl]-5,6-methylenedioxybenzofuran (euchrestafuran), respectively, by means of spectroscopic analysis.
