In a previous paper, authors reported that the toxic substances in the thermally oxidized oils were obtained in diethylether eluate (fr. III) when chromatographed on a silicic acid column. The present study is for investigation of the absorption and the distribution of the toxic fraction in the bodies of rats. <BR>Samples of thermally oxidized oils were prepared by heating soybean oil with air bubbling and fed to animals in 20 % of the diet for 4 weeks. After the feeding experiment, lipids were extracted from the feces, liver, and intestine and separated by column chromatography to determine the fr. III quantitatively. <BR>Results indicate that more than 55% of the toxic fraction was absorbed and that dimers of glyceride in the toxic fraction could be absorbed through the intestine.
