The formation of chelate complexes of dihydroqercetin (DHQ) with zinc and chromium asparaginates in aqueous solution is established and their interaction with a lecithin monolayer is estimated. On the basis of analysis of the surface pressure-molecular area isotherms, it is concluded that an increase in the molecular area from 0.54 to 0.80–0.90 nm 2 is indicative of the immobilization of DHQ complexes in the lecithin monolayer. It is shown that the concentration of the initial products of lipid peroxidacion-diene and triene conjugates-decreases to 24 % and 41 %, respectively, and that of the final products (Schiff bases) in the blood of patients treated by Oftalvit (containing DHQ and metal asparaginates) decreases to 46 % in comparison to values in the control groups.
