Problems of terminology applied for antioxidant properties of substances are being discussed. Selection of the term 'Antioxidant Activity' is being proved. New method of the determination of this index is offered, where electrode potential shift as a result of redox chemical reaction between substance to be determined and oxidized form of mediator system serves as a source of information. Good correlation is fixed between data obtained by potentiometric method and known chemiluminescent, Randox methods, and photometric method with the use of stable radical 2.2-diphenyl-1-picrythydrasyl. Accuracy and reliability of the results, simplicity of the analysis procedure and its self-descriptiveness make the method offered to become good alternative to the known methods of antioxidant activity determination.
