Phenolic compounds were extracted from radish (Raphanus sativus L. cv. Lucynka) sprouts using 50% acetone and 50% methanol. Used solvents didn’t have an influence on total phenolic compounds content. 50% MeOH was better solvent for flavonoids extraction. However when 50% aceton was used most of the phenolic acids were extracted. Radish sprouts extracts showed significant antiradical activity (54,33% for acetone extract and 56,08% for methanol extract), but this activity was significantly lower than those of synthetic antioxidants. Analyzed samples showed the ability to neutralize H2O2. Higher activity was obtained for methanolic extract (59,48%) then for acetone extract (53,84%). Acetone extract showed higher metal-chelating ability then methanol extract (45,33% and 32,24% respectively). In both cases activity of analyzed samples were higher than activity of synthetic antioxidants.
