Electrochemical measurements have advantages for the determination of antioxidant activity such as their use as a rapid proof of the antioxidant capacity of a lot of organics. The oxidation potentials measured by cyclic voltammetry (CV) have been used to compare the antioxidant strength of compounds such as phenolic acids, flavonoids, cinnamic acids, etc. [1,2], being the glassy carbon electrode (GCE) the more frequently used electrode. Coriander (Coriandrum sativum L.) is an annual and herbaceous plant, belonging to the Apiaceae family. Coriander is of economic importance since it has been used as flavoring agent in food products, perfumes and cosmetics [3]. In the present work the electrochemical oxidation of aquatic leaf extract of Coriandrum sativum L. which is cultivated in Nahavand has been investigated by cyclic and differential pulse voltammetry (DPV) techniques. The results show that aquatic leaf extract of Coriandrum sativum L. has strong scavenging capabilities and oxidized at low potentials in comparison of quercetin as a standard antioxidant. Also the effect of extract concentration and scan rates has been studied in the biological pH.
