In recent years, special attention is paid to the attraction of natural antioxidants in the ration of man. Therefore, among the known fruit cultures peach attracts the special attention. The aim of our researches was determination of antioxidant activity of biologically-active substances of vegetative and generative organs of species and cultivars of Persica, introduce in Right-bank Forest-steppe of Ukraine. Biochemical researches on peach were often covered by scientists of the Nikita botanical garden on territory of Crimea. Therefore, research of him biochemical properties in the Foreststeppe zone of Ukraine is actual. The experimental data evidently, that the investigated species substantially differ on these indexes. So fruits of Persica davidiana have significantly lower antioxidant activity (0,551 mgs/of ml) than sorts of Persica vulgaris (0,588-1,388 mg/ml). Among the cultivars of P. vulgaris were characterized by the highest of a quantity of late ripening fruit (inzhyrniy zhovtomyasiy (1,388 mg/ml) and the Osinniy syurpryz (1,249 mg/ml)). The cultivars of peach with early ripening fruit have low content of antioxidants in springs and considerably higher in leaves and a late ripening fruit have highest antioxidants in the springs and significantly lower in the leaves. The results show that the highest antioxidant activities of all the leaves are characterized by species studied, and least of all their available in peach fruits.
