[Cu(2+) complexes as inhibitors of free radical oxidation of lipids].

: Cu(2+) complexes of chelate ligands have been studied for their effect on oxidation of rat blood plasma lipids, sphingomyelin, lecithin by the method of chemoluminescence. The studied Cu(2+) complexes have been shown to possess pro-oxidant and antioxidant properties depending on their concentration. Antioxidant activity of alpha-tocopherol, ionol (2,6-di(tert)-butyl-4-methylphenol) and Cu(2+) complexes by the lipid oxidation has been compared.
