FIELD: physics, measurement.
SUBSTANCE: invention relates to physical and chemical analysis methods, particularly to analysis of solutions for quantitative determination of antioxidant activity. In the disclosed method, determination of antioxidant activity is carried out based on the difference in the number of paramagnetic particles of a stable radical, measured before and after chemical reaction of the particles of the radical with antioxidants.
EFFECT: goal of the present invention is to overcome shortcomings of existing methods and create a new method, which improves accuracy and rapidness of determination, and enables to quantitatively, in standardised units, establish antioxidant activity of a certain substance in an analysed sample and a mechanism for interaction of antioxidants with free radicals of diphenyl picryl hydrazyl.
