Nowadays, searching for new raw materials and sources of biologically active substances of plant origin is very important. The wide distribution, relative ease of isolation, and high physiological activity have made the practical application of the acid polysaccharide attractive. An intensive study of the relationship between the structure and physicochemical properties of acidic polysaccharides is currently underway. The objective of the research is to isolate and study the physicochemical properties of the acidic polysaccharide (pectic substances) isolated from the medicinal plant Portulaca (lat. Portúlacaolerácea) growing on the lower part of the Amu Darya. The article presents the results of the isolation and chemical study of the acid polysaccharide by paper and gas-liquid chromatography. It has been established that this carbohydrate complex is represented by pectin substances. Their qualitative and quantitative monosaccharide composition has been established. The physicochemical parameters and monosaccharide composition of garden purslane have been studied. According to chromatography, the monosaccharide composition consists of uronic acid, galactose, glucose, arabinose, xylose, and minor rhamnose. The obtained pectin substances from the garden purslane plant belong to high molecular weight acidic polysaccharides, arabinoglucouranans.
