The antioxidant properties of ethyl acetate extracts of fruits, leaves and bark of the Osage orange (Maclura pomifera) tree were studied by a kinetic method using the example of a model reaction of cymene oxidation. The extracts exhibit antioxidant properties. Findings of the research show that fresh orange maclura fruits contain the greatest amount of antioxidants. At a temperature of 348 K, the effective content of antioxidant substances is 1.05 · 10--3 mol/(l · mg). The analysis of the effective content of antioxidants in each extract revealed that it decreases when the extract is stored at room (289 K) temperature. Antioxidant activities of antioxidants were determined --- rate constants of InH + RO•2→ ROOH + In•. According to the content of antioxidants, the ethyl acetate extracts are distributed in the following order: fruits > bark > leaves, and according to antioxidant activity --- bark > fruits > leaves. The dependence of the effective content of antioxidants on the measurement temperature was examines. The study shows that the effective content of antioxidants increases, especially in the extracts of dried fruits, leaves and bark of Osage orange, with decreasing temperature. This is due to a decrease in the additional initiation of primary radicals as a result of the autoxidation of easily oxidizing substances contained in the extracts
