Antioxidant and Phytobiological Studies on Two Allium Cepa L. Extracts.

AIM To investigate the antioxidant potential of two Allium cepa L. extracts. MATERIAL AND METHODS The antioxidant activity of the two extracts (encoded EC1 and EC2) was assessed using two methods: DPPH (2,2-diphenyl-1-picrylhydrazyl) scavenging capacity and determination of their reducing power; phytobiological, studies were performed using grains of Triticum aestivum L., Falmura variety. RESULTS AND DISCUSSIONS EC1 and EC2 extracts had a particular affinity for binding DPPH radicals. At equivalent concentrations, the reducing power of EClextract was about 2 times higher compared to EC2, increasing with the concentration of the analyzed sample. The phytobiological study demonstrated that the investigated extracts had no cytotoxic and genotoxic potential.
