Abstract	The effect of 11-selenadodecylglyceryl-1-ether (11-SeDGE) at concentrations of 5 × 10$^{−4}$ and 1 × 10$^{−2}$ M on the autoxidation of sunflower oil with a natural content of 0.06% tocopherols at 100°C and at room temperature in the dark and of pure triacylglycerols of sunflower oil (TGSO) at 100°C was studied. The process was followed by peroxide concentration (peroxide value) determination and by ultraviolet (UV) spectroscopy. It was found that 11-SeDGE acted synergistically with the tocopherols in sunflower oil in a dose-dependent manner to delay oxidation at 100°C. The results from the UV spectra indicated that 11-SeDGE decomposed the initiators of the process, the hydroperoxides, into inactive products. During oxidation of pure TGSO (i.e, depleted of tocopherols) at 100°C, 11-SeDGE retarded the process without a pronounced induction period. At room temperature, 11-SeDGE showed a slight prooxidative effect on sunflower oil oxidation. Taking into account the established prooxidative effect of the two hydroxy groups in a molecule such as 11-SeDGE, it was recommended to study the lipid autoxidation in the presence of selenium compounds that do not contain such prooxidative groups.
