4. Conclusions
Extraction of antioxidant phytocompounds from Fajr rice bran with MeOH produced a significantly greater yield and total content in phenolic compounds than ethanol and ethyl acetate solvents, which lead to high antioxidant activities of extracts in inhibiting linoleic acid peroxidation, DPPH radical scavenging ability and reducing power. The strong antioxidative activity of rice bran extracts might be due to the presence of mainly tocotrienols or the synergistic effect of tocopherols and tocotrienols.
