To develop cheaper and safer natural antioxidative substance instead of synthesized ones, the extract of skipjack meat was examined for the antioxidative effects and factors. Amino-N of skipjack meat extract was 15.3 mg/100g, and the extract apparently showed inhibitory effect on the oxidation of methyl linoleate. Antioxidative activity of extract revealed a tendancy to reduce slightly in proportion to hydrolyzing. When extract was dialyzed in distilled water, the outer fraction had a strong inhibitory effect on the oxidation of nethyl linoleate, while the inner fraction showed no effect. From the omission test and chemical analysis, the major antioxidative factors of skipjack meat extract were amino acids such as anserine, histidine, carnosine and alanine. As well nucleotides such as AMP, hypoxanthine seemed to act an auxiliary role in antioxidative effect of that.
