Abstract

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.
