ANTIOXIDANT PROPERTIES OF HORSERADISH (ARMORACIA RUSTICANA) – PILOT STUDIES

Abstract

The aim of the study was to evaluate the antioxidant properties of horseradish extracts (Armoracia
rusticana). The study’s material consisted of wild, horseradish samples coming from three different regions of
Poland (Mazowsze, Wielkopolska and Podlasie). Antioxidant activity was investigated using DPPH• free radical,
and the final result was converted into the equivalent of the antioxidant activity of vitamin C. Studies have
shown that one of the samples had significantly higher antioxidant activity than the other two, whose antioxidant
potential was similar from a statistical point of view. It was calculated that 1 g dry substance of horseradish
samples had an antioxidant activity corresponding to 4.31 – 8.78 mg of vitamin C.
