October, 71, Ufa, 450054 (Russia), e-mail: mudarisova@anrb.ru 2 Saint Petersburg State University, Universitetsky Pr., 26, Stary Petergof, 198504 (Russia), e-mail: rmislamova@mail.ru Thermodynamics of a complex formation of iodine and arabinogalactan, iodine and polymeric form oxidized arabinogalactan, iodine and oligomeric form of oxidized arabinogalactan in water and aqueous-alcoholic solutions at various temperatures by spectrophotometry methods was investigated. Structure and constants of stability of formed complexes, optimum conditions of reaction were established. Communication between donor ability of polysaccharide matrixes and stability of reaction products was revealed. Changes of enthalpy and entropy of reaction were calculated. There are no essential restructurings of compounds at iodine complex formation with arabinogalactan or its oxidized forms.the active centers in poly-and oligosaccharides which are directly reacting with iodine are both hydroxyl groups, and C-O ether bond of pyranose and furanose rings of poly- and oligosaccharides. Keywords: arabinogalactan and its oxidized form, iodine complexing, spectroscopy, stability constants, enthalpy, entropy. References 1. Antonova G.D., Tjukavkina N.A.
