| Abstract: | It is shown that the interaction of polyvinylpyrrolidone and human serum albumin with a natural flavonoid quercetin in aqueous medium results in the formation of 1 : 1 supramolecular complexes. As a result of complexation, the optical and protolytic properties of the flavonoid change and its concentration in solution increases considerably. The adsorption of quercetin on silica particles in the presence of polymers is discussed. |
