| Summary: | This paper describes the technology developed by us for obtaining some physiologically active polysaccharides (pectic substances and hemicellulose) from domestic plum. The isolated products were identified by IR spectroscopy, which made it possible to determine their qualitative characteristics. The dried fruits of Prunus domestica L. were analyzed for the content of low molecular weight substances, then polysaccharides were isolated from plant materials, hydrolyzed, acetylated, and the monosaccharide composition of each polysaccharide was studied by a combination method of gas chromatography and mass spectrometry. A thermal analysis of the obtained polysaccharides was also carried out to determine their thermal stability.
