Phytochemical Investigation Of Erythrina Corallodendron. (Fabaceae)
The phytochemical analysis of the 70% methanol extract of both the flowers and the stems of Erythrina Corallodendron L. (Fabaceae) cultivated in Egypt resulted in isolation and identification of seven flavonoids: two isoflavonoids: daizdizen (1), genistein (2), three C-glycosides: vicenin-2 (3), schaftoside (4), isoscaftoside (5), one O-glycoside: Kaempferol 3-O- β-D-sophoroside (6), one petrocarpan: (6aR,11aR)-3,9-dihydroxypetrocarpan (7) and five alkaloids: one indole alkaloid: hypaphorine (8), four erythrinan alkaloids: erysodine (9), erythbidin β (10), 8-oxoerythraline (11) and 10,11-dioxoerythraline (12). Compounds 1, 2, 4, 5, 6, 7, 10, 11, and 12 are reported for the first time from this species. The structures of the isolated compounds were elucidated using UV, 1D and 2D NMR and HRESIMS techniques.
