Primary authors



The study of water solutions of linear (dextran) and branched (arabinogalactan) polysaccharides with Denol substance (Bismuth potassium citrate, ISSCM SB RAS) using SAXS, nuclear magnetic resonance (NMR), transmission electron microscopy(TEM) and gel permeation chromatography (GPC) were performed. It was shown the difference in the solubility of polysaccharides in mixtures with Denol. GPC were confirmed the existence of large Denol molecules in aqueous solutions (result of previous investigations of Denol). NMR investigation (1H and 13C), TEM and SAXS confirm a presence of interaction between Denol and linear polysaccharide. The authors thanks Prof. Yu.I. Yukhin and Dr. E.S. Naydenko for providing of a Denol samples. This work were supported of Russian Foundation for Basic Research (grant 15-29-01297 ofi_m).
