- Аннотация: The carotenoid astaxanthin has a variety of biological activities and antioxidant properties. Due to its lipophilic nature, astaxanthin can be used to protect against lipid peroxidation, in which iron ions play an important role. The effect of Fe2+ ions on the oxidative degradation of astaxanthin in phospholipid liposomes was previously studied. In this paper, we study the interaction of astaxanthin with Fe3+ and Fe2+ in organic solvents of various polarities in the absence of lipids. It is shown that in the presence of Fe3+, astaxanthin oxidation and degradation occurs in methanol and dichloromethane. The formation of an intermediate product with an absorption maximum at 876 nm is recorded spectrophotometrically. Electron paramagnetic resonance (EPR) proves the radical nature of the intermediate product, whose signal intensity decreased over time, with the signal remaining for up to three days. Based on the obtained results, it can be assumed that the radical product formed in the reaction with Fe3+ is the radical cation of astaxanthin. At the same time, no changes are detected when astaxanthin is incubated with Fe2+: the absorption spectrum does not change andno radical product is formed.
