The aim of this work was to assess antioxidant activity of the complex ethoxyquin-palmitoyl-L- ascorbis (EQ-PA). The tested material was the evening primrose oil. The peroxidation reaction was UV-stimulated. The intensity of the process of oil deterioration was assessed from the following indices: epihydrine aldehyde content, iodine, peroxide, anisidine and Totox values, and UV absorption spectra for the 1% solutions in cyclohexane. The examined compounds were found to behave as antioxidants at concentration 0,01 - 0,1%. Stronger effect was observed for the 0,1% EQ-PA.
