Abstract: Background: Cornlettes has the potential to be used as functional pharma-nutritional ingredient in food products because of the occurrence of various bioactive compounds in it. Objective: This study was conducted to determine antioxidant and scavenging activities of phenolic rich-fractions of cornlettes extracts. Methods: DPPH radical scavenging, Ferric reducing antioxidant power and Phosphomolybdenum assay were used to determine anti-oxidative and scavenging properties of cornlettes fractions. Results and Discussion: The ethyl acetate fraction was possessed higher antioxidant activity in each antioxidant assay tested. In DPPH assay, the IC50 value of DPPH scavenging activity of the ethyl acetate, hexane, water and crude were 0.28 mg/mL, 0.26 mg/mL, 2.10 mg/mL and 1.85 mg/mL, respectively. The percentages of DPPH reduction in ethyl acetate and hexane possessed more effective anti-oxidative capacity as compared to water and crude fractions. For FRAP assay, the ethyl acetate fraction significantly exhibited the highest reducing power activity of antioxidants compared to other fractions. The IC50 value of FRAP activity of the ethyl acetate, hexane, crude and water were 0.40 mg/mL, 0.82 mg/mL, 2.24 mg/mL and 1.58 mg/mL, respectively. In addition, phosphomolybdate assay was also shown that ethyl acetate fraction had the highest total antioxidant capacity than other fractions. However, at low concentration (0.05-0.2 mg/mL), each fraction was not significant to each other. Concusion: The ethyl acetate fraction was possessed higher antioxidant and scavenging capacities followed by hexane, crude and water fractions in each antioxidant assay tested.
