Abstract
Two new erythrinan alkaloids, 10,11-dioxoerythraline (1) and 8-oxoerythrali ne epoxide (5) have been isolated from flowers of Erythrina x bidwillii. Th eir structures were elucidated by spectroscopic analyses and chemical evide nce. 8-Oxoerythraline epoxide is the first erythrinan alkaloid possessing a n epoxy ring.
