Electrochemical Study of the Antioxidant Activity and the Synergic Effect of Selenium with Natural and Synthetic Antioxidants

Abstract

In this paper we propose two different electrochemical methods such as Cyclic Voltammetry (CV) and Osteryoung Square Wave Voltammetry (OSWV) to study the free radical scavenging ability of Selenium (Se) and natural and synthetic antioxidants. The originality of this paper is based on the study of the synergic effect of Se, not only with a-Tocopherol, but with a variety of antioxidants. As a result, we find an important synergism, in vitro, between Se and some other natural and synthetic antioxidants in the aqueous medium.
