Electrochemical Evaluation of Antioxidant Activity and Herb-Herb Interaction of Iranian Echium amoenum Fisch and Citrus aurantifulia aqueous extracts

Electrochemical oxidation of Echium amoenum Fisch extract has been studied in the presence of Citrus aurantifulia aqueous extract in aqueous solution and biological pH, using cyclic voltammetry, and differential pulse voltammetry methods. The results revealed that the electrochemically generated compounds in Echium amoenum Fisch extract, participate in the chemical reaction with phenolic compounds in Citrus aurantifulia extract. Based on these results there is a herb-herb interaction between this two extract, that can be reduce the antioxidant activity of Echium amoenum Fisch extract. Also Antioxidant activity of this extract has been compared with the galic acid, salicilic acid and quercetin as standard antioxidants.
