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. R...
