Electrochemical Oxidation, Evaluation and Comparison of Antioxidant Activity of Zingiber Officinale Roscoe root and Cinnamomum Verum. Aqueous Extracts

In this report, the electrochemical study of the Zingiber officinale Roscoe root and Cinnamomum verum aqueous extract as herbal medicine were conducted. The antioxidant activity of these plants were evaluated using the cyclic voltammetry technique. The results showed that this extracts were oxidized at low potentials compared with quercetin, salicylic acid and gallic acid as standard synthetic antioxidants. Also the DPPH assay (free radical scavenging activity) was applied in order to estimate antioxidant activity.
