Phytochemistry and Biological Activities

The flavonoids of nine selected species belonging to different tribes of family Brassicaceae (Cruciferae) native to Egypt were surveyed, viz. Rorippa palustris, Coronopus squamatus, Eremobium aegyptiacum, Moricandia nitens, Brassica tournefortii, Farsetia aegyptia, Matthiola livida, Anastatica hierochuntica and Sisymbrium irio. Thirty-eight compounds were isolated and identified, which included six flavonol aglycones, 24 flavonol glycosides including 14 flavonol 3,7-diglycosides, one flavone aglycone, three flavone O–glycosides, two glycoflavones and two dihydroflavonoids. A numerical analysis based on a combination of 97 morphological, anatomical and chemical characters revealed two series, two subseries, two clusters and two groups. The interrelationships between the studied species are discussed.
