Abstract:Phytochemical investigation of the whole plants of Crotalaria sessiliflora L. led to the isolation of four flavonoids. The structures of these compounds were identified as 2',4',5,7-tetrahydroxyisoflavone (1), 2',4',7-trihydroxyisoflavone (2), 4',7-dihydroxyflavone (3), and isovitexin (4) using spectroscopic analysis. Among these, compounds 2, and 3 have not been reported from Crotalaria species, whereas compounds 1, and 4 were reported from this plant for the first time.
Keywords:Crotalaria sessiliflora  Leguminosae  Isoflavone  Flavone  Flavone glycoside
