Summary:The structure of the arabinogalactan (AG) and its sulfates was characterized by method of FT Raman spectroscopy. It was established, that after sulfation of AG with a chlorosulfonic acid in pyridine, there was an introduction of sulfate groups in arabinogalactan chain. As shown by an X-ray diffraction (XRD), initial samples of MCC had amorphous structure, and in the course of sulfation there was a further amorphization of the structure of a material. By use of scanning electron microscopy (SEM) and atomic-force microscopy (AFM) was shown, that sulfated arabinogalactan synthesized in pyridine, have different morphologies from starting arabinogalactan.
