Activité Antioxydante Des Composés Phénoliques De Quatre Variétés De Lierre Grimpant Récoltée à Dellys

Much of the interest of current research is the study of naturally occurring antioxidant molecules. This work aims to evaluate the antioxidant power of phenolic compounds extracted from the leaves of four varieties of climbing ivy. The phytochemical screening of the vegetal drug has resulted similarities in several chemical compounds for the four varieties of climbing ivy. The concentrations obtained ranged between 16.46 ± 0.08 mg EAG / g MS (H. algeriensis varmarengo glory) and 11.67 ± 0,05 mg EAG / g MS (H. helix var green ripple). The study of the antioxidant activity has shown, for the phenolic compounds of four varieties, a very important anti-radical activity. The IC50s are 0.19 mg / ml (var glory of marengo) and 0.27 mg / ml (var glacier) for the varieties of H. algeriensis. Those of the species H. helix are 0.26 mg / ml (varcommon) and 0.33 mg / ml (var green ripple).
