摘　　要：Five hitherto unknown isoflavonoids,namely erythrinins D-H(1-5),were isolated from the ethanol extract of Erythrina arborescens.Their structures were elucidated on the basis of extensive spectroscopic studies.In addition,the structure of anagyroidisoflavone A(6a)has been revised as 1″-O-methylerythrinin F(6)by re-analysis of the original spectroscopic data.
