The aim of this work was to optimize a GFC method for the analysis of bioactive metal (Cu, Co and Fe) complexes with olygosaccharides (dextran and pullulan). Bioactive metal complexes with olygosaccharides were synthesized by original procedure. GFC was used to study the molecular weight distribution, polymerization degree of oligosaccharides and bioactive metal complexes. The metal bounding in complexes depends on the ligand polymerization degree and the presence of OH groups in coordinative sphere of the central metal ion. The interaction between oligosaccharide and metal ions are very important in veterinary medicine, agriculture, pharmacy and medicine.
