The research was conducted to observe the effect of thermal oxidation at 200 deg. C, 9.0 hours to the change of the physico-chemical properties and mutagenic activity of monomer and dimmer fractions of oxidized frying oils: palm, corn, soybean and sunflower oils. Results of gas chromatography analysis showed that the physico-chemical properties and fatty acid composition of samples were similar to the codex alimentarius standard. Column chromatography fractionation of oxidized oils produced 56.70-59.14 percent monomers, 32.46-38.00 percent dimmers and 3.23-8.65 percent olygomers. The mutagenicity studied with or without adding S-9 was positive to all monomer and dimmer fractions except for corn oil monomer and negative to the unheated frying oils
