title: Erythrinan alkaloids and isoflavonoids from Erythrina poeppigiana.
abstract: A new erythrinan alkaloid, 8-oxo-alpha-erythroidine epoxide, was isolated from wood of Erythrina poeppigiana together with the five known compounds, 8-oxo-alpha-erythroidine, erystagallin C, alpinumisoflavone, erythrinin C and eryvarin A. Their structures were elucidated on the basis of spectroscopic evidence.
