Abstract

In the past few years, natural antioxidants have attracted considerable interest in preventive medicine and in the food industry. Therefore attention has been focused on the characterization of the antioxidant properties of extracts from several plant materials. Differential pulse voltammetry is an electrochemical method which could be used as a quantitative tool to evaluate the antioxidant capacity of a compound. In this research differential pulse voltammetry has been used to evaluate and quantify the antioxidant capability of a selected number of medicinal plants extracts. Results indicated that the method has the potential to be applied on different plant extracts for quantification of their antioxidant activities. Further capabilities of the method in predicting the type of antioxidants which are present in plant extracts are also investigated. Differential pulsevoltammetry could be introduced as a new screening method for antioxidant activity of pants total extracts. It could also be used to quantify the total antioxidant property of a total extract.
