This study aimsto determine the totalcontent of polyphenols and the antioxidant activity by DPPH spectrophotometricallyin rutabaga (Brassica napusL. var. napobrassica) samples, cultivated in the Trenčín region, in the Púchov district, at the border of the White Carpathian and Javorníky mountains, Slovakia. For analysis were used three types of rutabaga, named after the collection sites(Mestečko, Lúky 1, Lúky 2). The total polyphenol content in rutabaga was ranging from 2.41 (Mestečko) to 2.82 mg GAE.g-1dry weight (Lúky2).It was established that that the studied rutabaga samplesdo not show a significant difference in the total content of polyphenols between the collection locations.In theantioxidant activity of rutabaga, differences were confirmed in AAs. A statistical difference was established between locations Lúky 2 and Mestečko.DPPH radical scavenging activity values were from 5,19 (Mestečko) to 7,49 μmol TE.g-1 DW (Lúky 2). Spearman's test showed a positive relationship between both methods used. Theseresults confirm the promising potential of rutabaga use in functional food preparation.
