STUDY OF SORPTION PROPERTIES OF WASTE PROCESSING FRUITS AND LEAVES OF ALDER SPECIES ALNUS INCANA(L.) MOENCH A. GLUTINOSA (L.) GAERTH

Abstract: The growing need for enterosorbents dictates the need to search for new economically profitable raw materials for obtaining medicines of this group. The attention of researchers is increasingly attracted by plant waste from the pharmaceutical and food industries, the use of which will not only expand the range of modern enterorbents, but also solve the problem of reducing the cost of phytopreparations. 
The aim of the study was to study the adsorption capacity of waste from the processing of coplodia and alder leaves of pharmacopoeia species in relation to standard markers in in vitro tests. The object used was a cake of gray and black alder leaves, as well as a cake of alder coplodia (a mixture of two types), sold according to the FS Fructus Alni, obtained by extraction of raw materials with 70% ethyl alcohol, dried in a drying cabinet at 105 ° C with subsequent grinding. Crushed cakes were fractionated using a set of sieves, fractions with a particle size of no more than 0.5 mm were selected for research. The crushed samples themselves, as well as samples that underwent additional processing, were used as potential sorbents. Standard technologies aimed at increasing porosity were used. In the course of the study, the adsorption capacity of the obtained cakes of raw materials was evaluated by methylene blue and gelatin in comparison with similar indicators of traditional enterosorbents - the preparation "Polyphepan" and microcrystalline cellulose. The comparability of the data obtained allows us to consider the studied raw materials as a promising source of obtaining enterosorbents using waste-free technology.
