A wide variation on total phenolic content was observed in raw vegetables, ranging from 44.94 ± 0.47 (beet, Beta vulgaris L. subsp. vulgaris) to 350.94 ± 5.18 (red radish, Raphanus sativus L.) μg gallic acid equivalent/mg of sample. Considering uncooked vegetables, the order of total antioxidant activity determined by β-carotene bleaching assay was beet > red cabbage > broccoli > white cabbage > black radish > kale > turnip > red radish. In DPPH• assay, kale had an exceptionally high antioxidant activity followed by red cabbage, broccoli, turnip, black radish, beet, white cabbage, and red radish.TAYLOR & FRANCIS INC2014Articlehttps://rdlopen.rawdatalibrary.net/r/gumushane/13232https://doi.org/10.1080/10942912.2011.6192921532-2386enInternational Journal of Food Propertiesinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://gumushane-rdlopen.rawdatalibrary.net/tr/items/gumushane/13232
