Abstract
Medicinal plants occupy a special place among the sources of pharmaceutical substances. Long-term experience of folk, traditional and official medicine of different countries confirms the effectiveness of the use of medicines of plant origin for the prevention and treatment of various diseases. Advantages of their use in comparison with the products of chemical synthesis, determine the relevance of expanding the nomenclature of currently used medicines by means of studying new plant species. Black currant shoots, as easily available for harvesting raw materials, are of interest for study in order to establish the possibility of their use in scientific medicine, so at the Department of Pharmacognosy FGBOU VO "PGFA" Ministry of Health of Russia conducted studies of shoots and leaves of black currant. The article presents the results of isolation and chemical study of polysaccharides of shoots and leaves of black currant wild and cultivated by paper chromatography and spectrophotometry. It is established that this carbohydrate complex is represented by water-soluble polysaccharides (WPS), pectin substances (PS), hemicelluloses (HC). The qualitative composition of monosaccharides by fractions was established. The presence of galactose, glucose, fructose, arabinose, rhamnose in fractions of GRPS and SP and glucose and xylose in HC was proved. The quantitative content of polysaccharide fractions was studied. The predominant fraction in the polysaccharide complex of shoots and leaves of black currant is pectin substances.
