Abstract

The antioxidant activities of methanol extracts of sixteen samples were tested using 1.1-diphenyl-2-picryl hydrazyl(DPPH) reactivity and TBARS substances assay in vitro. The methanol extracts of the rice brans from three wild rice -O. minuta, O. rufipogon, and O. barthii-were found to be the most effective in DPPH radical scavenging activity. The next effective ones were the rice brans of Heugjinjubyeo and leaves of Tapgolbori. When tested on lipid peroxidation using a lipid peroxidation generation system mediated by $H_2O$ $_2$ /Fe $^{2+}$ in rat liver homogenates, the brans and hull of wild rice (O. minuta, O. rufipogon, and O. barthii) and rice bran of Heugjinjubyeo exhibited protective activities against lipid peroxidation in the order of effectiveness.s.
