FEATURES OF POLYSACCHARIDES OF ARTEMISIA ANNUA L. AND SALVIA OFFICINALIS L., GROWING IN UZBEKISTAN

The article examines polysaccharides isolated from two medicinal plants – Artemisia annua L. and Salvia officinalis L., growing in Uzbekistan. Both plants are known for their healing properties, such as antioxidant, anti-inflammatory and antitumor activity, which makes them promising sources of biologically active compounds. In the work, the main plant polysaccharides, including water-soluble polysaccharides, pectin substances and hemicellulose, were isolated and characterized for the first time, and their monosaccharide composition was established. In the course of the work, the polysaccharides were isolated and purified, after which their structural and chemical features were studied using methods such as IR spectroscopy, titrimetry and gas-liquid chromatography. The results showed that the obtained complexes are represented by water-soluble polysaccharides (4.1–6.2%), pectin substances (4.0–8.6%), hemicellulose (1.0–5.2%) and the main components of the isolated polysaccharides are arabinose, xylose and rhamnose, which indicates their complex structure and potential biological activity. The study revealed the neutral-acidic nature of the polysaccharides and the presence of functional groups such as carboxyl and esterified carboxyl groups, which suggests their high complexing ability. Such compounds can be used as natural antioxidants and immunostimulants, as well as for the creation of pharmaceutical and food additives.
