20.500.12556/DiRROS-24160 Total polyphenol content and antioxidant activity of rutabaga (Brassica napus L. var. napobrassica) roots 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. rutabaga polyphenols antioxidant activity rumena koleraba podzemna koleraba fenolne spojine kemična sestava antioksidativna učinkovitost true false true Angleški jezik Slovenski jezik Copyright (c) 2024 Monika Cifrová, Alena Vollmannová, Tomáš Tóth, Marek Šnirc, Ivan Kreft Neznano 2025-11-18 08:42:13 2025-11-19 09:30:01 2025-11-20 03:44:37 0000-00-00 00:00:00 2024 0 0 Nasl. z nasl. zaslona; Opis vira z dne 3. 12. 2024; Str. 1-4 no. 3, [article no.] e11568 Vol. 14 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2024-01-01 633 1338-5178 10.55251/jmbfs.11568 217475075 https://office2.jmbfs.org/index.php/JMBFS/article/view/11568 1 1d82a793-c452-11f0-94a7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=35960 RAZ_Cifrova_Monika_2024.pdf RAZ_Cifrova_Monika_2024.pdf 1 008CA31839C7056D8432568DC3032A05 96514ff8bad59a5846d03ab8e6144cf507047bf81b6008609fb2928aafd108e5 d38d9ac2-c521-11f0-94a7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=36003 Inštitut za nutricionistiko 0 0 0
