We extracted phenolic and flavonoid metabolites from black rice bran (BRB) using a 70% methanol solvent. A rotary evaporator was used to fractionate concentrated extracts into NHF (n-hexane fraction), CF (chloroform fraction), EAF (ethyl acetate fraction), NBF (n-butanol fraction) and AF (aqueous fraction). Antioxidant activity was evaluated as the scavenging activity of DPPH (1,1-Diphenyl-2-picrylhydrazyl) radical, superoxide radical, nitrite activity, and reducing power. The biological content of phenol (856.8±10.9 ㎎ GAE/g) and flavonoid (867.6±14.7 ㎎ QE/g) was exhibited the highest EAF. The total antioxidant activity were exhibited in EAF and lowest in NHF. The biochemical content of phenol and flavonoid was exhibited higher in EAF than the other extracts. Overall the present results indicated that higher concentrations of phenol and flavonoid from EAF might increase antioxidant activity but further research is needed to conform the compound specificity for the enhanced antioxidant activity of EAF.
