In addition to the known Compounds senegalensin, lupinifolin, erythrisenegalone, and auriculatin, two new isoflavones named erysenegalensein H and erysenegalensein I were isolated from the dichloromethane extract of the stem bark of ERYTHRINA SENEGALENSIS DC. On the basis of spectroscopic methods their structures were elucidated as 5,2',4'-trihydroxy-8-(gamma,gamma-dimethylallyl)-2''-hydroxyisopropyldihydrofurano[4'',5'':6,7]-isoflavone and 5,2',4'-trihydroxy-8-(gamma,gamma-dimethylallyl)-3''-hydroxy-2'',2''-dimethyldihydropyrano [5'',6'':6,7]-isoflavone, respectively.
