POLYEXTRACT OF THE FRUIT OF ZIZIPHUS JUJUBA: STUDY AND STANDARDIZATION

The main quality indicator for polyextracts is the content of biologically active substances (BAS). Depending on the presence of various groups of biologically active substances, the consistency and stability of the extracts, the regulatory documentation for the extracts contains requirements regarding their composition and quality. Liquid extracts are standardized according to the content of ethyl alcohol. Thick and dry extracts are assessed by their moisture content. Heavy metals are determined in all extracts. Standardization of plant extracts is carried out in accordance with the current regulatory documentation, namely the State Pharmacopoeia of the Russian Federation [1-4]. In this study, using the following methods: GC - MS, TLC and UV spectrophotometry, we studied extracts of the fruits of the common jujube Ziziphus Jujuba Mill., obtained by cascade extraction of raw materials with a solvent system with increasing polarity for maximum depletion of raw materials according to the main groups of biologically active substances. As a result of the work, the quality indicators of the polyextract of jujube fruits were determined and the drug was standardized in terms of the content of total flavonoids and total polysaccharides. The work was carried out in accordance with the research topic of the Federal State Budgetary Scientific Institution VILAR FGUU-2022-0011.
