Rice bran is a byproduct of rice (Oryza sativa) milling that still lacking in its utilization and was limited used for animal feed.Previous studies have shown that rice bran contains high nutrient compounds. This study was conduct~d to deterni1ne antioxidant activity of n-hexane extract of rice bran using diphenyl picryl hydrazil hydrate (DPPH) as stable free radical in spectrophotometric methods. The an tioxidant activity of rice bran was determined in operating time about 35 minutes and maximum wavelength 516,54 nm and antioxidant stret1gth shown by EC50 values. The result showed that rice bran positively has antioxidant activity with EC50 4099,55± 181,93 bpj .
