The purpose of this study was to evaluate the effects of barley cultivars [Saechalssalbori (SC), Huinchalssalbori (H), and Saessalbori (S)] and different milling recovery rates (95%, 85%, and 75%) on antioxidant and tyrosinase inhibitory activities. Results show that the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activities of SC, H, and S extracts based on 95% coverage were 5.90, 4.63, and 17.57 mg Trolox equivalent/g sample, respectively. The ferric-reducing antioxidant potential (FRAP) value ??of S extract with 95% milling recovery was the highest at 1,041.53 μM. Tyrosinase inhibitory activities of SC, H, and S extracts were 30.64, 38.62, and 60.64%, respectively. Total polyphenol contents of SC, H, and S extracts based on 95% coverage were 48.87, 44.58, and 172.51 μg gallic acid equivalent/g sample, respectively. The total flavonoid content ??was highest in S extract with 95% milling recovery. The DPPH radical scavenging activity, FRAP value, tyrosinase inhibitory effect, total polyphenol, and flavonoid contents of barley extracts were reduced as milling recovery rate decreased. The results of this study suggest that milling recovery and cultivar of barley are important factors to improve the antioxidant and tyrosinase inhibitory activities of barley.
