Abstract

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.
