METHOD FOR DETERMINING THE TOTAL ANTIOXIDANT ACTIVITY OF EXTRACTS FOR TIPPING BY VOLTAMMETRY modified electrodes

摘要

A method for determining the total antioxidant activity of the tea extracts by voltammetry on the modified electrode comprising preparing a modified electrode and determination of antioxidant activity of tea extracts, which is conducted at a potential scan rate of 40 mV / s and the operating potential range of 0 to -1.2 V, to calculate using kinetic criterion reflecting the number of active forms of oxygen that react with the antioxidant for a minute time, as a supporting electrolyte to water-sleep tovyh media using 0.1 mol / dmNaClO dissolved in dimethylformamide.
