Abstract
The antioxidant activity of lipids extracted from peats and sapropels from Tomsk and Novosibirsk Regions and Khanty-Mansi Autonomous Okrug is estimated by microcalorimetry. The presence of antioxidants (AO) in the lipids of all peats under study and in a sapropel from the Dolgoye Lake is confirmed by the presence of an induction period (950–14000 s) on the heat release curve and the decrease in the final rate of the model reaction of the initiated cumene oxidation by 25–90%. The total amount of lipid antioxidants varying within the range (22–183)∙10-3 mol/kg is determined by the degree of inhibition of the oxidation reaction. The concentration of identified orga...
