Alkaloids from erythrina corallodendron linn and their pharmacological activities

ABSTRACT

During a careful search for bioactive alkaloidal constituents from the alcoholic extract of Erythrina corallodendron Linn leaves, three alkaloids namely, erysodine [1], erythirinine [2] and 8-oxoerythrinine [3] were isolated. These compounds are reported here for the first time from such species. Structures of the isolated compounds [1-3] were assigned by intensive studies of their NMR and MS spectral data and comparison with related structures. The pharmacological activities of the isolated alkaloids are presented
