Abstract

Rutin is one of the most common found flavonoid, containing quercetin as a flavonol aglycone. Its structure consists of a two aromatic (phenolic) rings connected through one heterocycle containing oxygen [1]. The high number of OH groups, as well as, its aromaticity justifies the use of an electrochemical method in its analyses [2]. Cyclic voltammetry has been applied in order to investigate the redox oxidation process of rutin on a glassy carbon electrode, as working electrode. Additionally, the platinum electrode has been used as a reference electrode and a graphite stick has been employed as counter electrode. Its electrochemical properties has been studied in different pH values by use of a few different buffer solutions in pH range from 2.8 to 8.8. The potential applied on the surface of the working electrode in the range of -0.4 to 0.6 V, was used in scanning the redox process of rutin. The reversible oxidation in physiological pH has occurred on Epa = 0.198 mV and Epc = 0.221 mV, but the results have shown that its oxidation is a pH dependent electron transfer process. Additionally, the adsorption of rutin was noted. The application of these data considering the redox behavior of rutin could be used in prospecting of its mechanism of oxidation and structure-antioxidant activity relationship, as well as developing a method for fast estimation of its antioxidant activity.
