Polish wines - Opis:
- The wine is famous and popular drink having properties of reactive oxygen species scavenging. In this paper we study the antioxidant activity of the selected wines produced in the south-east region of Poland, in Subcarpathian Voivodeship, in the Podkarpacie region. We have concentrated our studies on the superoxide radical anion O2 •–. We have used electron spin resonance spectroscopy (ESR) as it is the best method for radical detection. The nitrone spin trap α-(4-pyridyl-1-oxide)-N-tert-butylnitrone (POBN) has been used in the experiment. The radical scavenging ability of wines were determined from the changing intensity of the spectrum in time.
