Comparative Antimutagenic and Antioxidative Activities of Rice with Different Milling Fractions

摘要: Antimutagenic and antioxidative activities in the different milling fraction of rice(Oryza sativa L., illpumbyeo) were investigated. Twelve fractions including embryo, bran(I, II, III, IV all) milled rice(I, V) obtained by abrasive milling. effects against Trp-P-2-induced mutagenicity shown as for embryo fraction, bran rice salmonela typhimurium reversion assay. Milled V, inner with 80.9% yields, showed highest antimutagenic activity among Antioxidative activity, measured peroxide value(POV) was higher embryo(28%) than fractions. In terms thiobarbituric acid(TBA). embryo. exhibited 14, respectively. electron donating ability(EDA), 45% fraction. if correlated POV (r=-0.471, p
