Erythrinan Alkaloids and Isoflavonoids from Erythrina poeppigiana

Abstract

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