A polynuclear complex of pullulan oligomers of formula (I): wherein n = (100-8200), obtained by process of synthesis of soluble pullulan with insoluble iron (III)-hydroxyde of formula (II): wherein n=(900). The process of synthesis is characterized by technical simplicity and economy. In accordance with suggested process, first of all, preparation of pullulan for synthesis, including its characterization (determination of RG, Mw, Mn, [ eta ]) is carried out, and subsequently its hydrogenation is carried out in order to eliminate reducing groups, iron(III)-hydroxyde gel is prepared, and synthesis of the complex can start. Obtained complex is afterwards prepared for pharmacological use and it is subjected to the subsequent physical and chemical processes of purification. The preparation obtained in such a way is used for prevention and treatment of syderopenic anemia in human and veterinay medicine. |
