  Four flavonoids in the roots of Euchresta Formosana

  摘要：

  Four new flavonoids from the roots of Euchresta formosana were characterized as 5,5'-dihydroxy-8-gamma,gamma-dimethylallyl-{6'',6''-dimethylpyrano(2'',3'':7,6){-{6'''',6''''-dimethylpyrano-(2'''',3'''':4',3')}-coumaronochromone (euchretin D), 5,5'-dihydroxy-6-gamma,gamma-dimethylallyl-{6'',6''-dimethylpyrano(2'',3'':7,8)}-{6'''',6''''-dimethyl-pyrano-(2'''',3'''':4'3')}-coumaronochromone (euchretin E), 5,2'-dihydroxy-8-gamma,gamma-dimethylallyl-{6'',6''-dimethylpyrano (2'',3'':7,6)}-{6'''',6''''-dimethylpyrano-(2'''',3'''':4',5')}flavanone (euchrenone a11) and 5,2'-dihydroxy-6-gamma,gamma-dimethyl-allyl-{6'',6''-dimethylpyrano(2',3'':7,8)}-{6'''',6''''-dimethylpyrano(2'''',3'''':4',5')} flavanone (euchrenone a12) by means of spectroscopic analysis.
