Fifteen alfalfa varieties cultivated in Turkey were researched to compare the antioxidant potential of their seeds and find differences between the varieties. The total phenolic (TP) content, DPPH•, and ABTS•+ scavenging activities, and ferric-reducing antioxidant power (FRAP) of alfalfa seed methanol extracts were determined. TP contents of extracts were found between 37.03 and 54.04 mg GAE/g. ABTS assay results ranged between 0.100 and 0.158 mmol Trolox/g extract, and FRAP changed from 389.90 to 791.02 µmol Fe2+/g extract. The results demonstrated that the differences between the alfalfa varieties were significant (p < 0.01) in terms of analyzed characters. © 2021, Centenary University. All rights reserved.
