CHEMICAL COMPOSITION AND BIOLOGICAL PROPERTIES OF THE KIDNEYS OF POPULUS NIGRA L. OF THE CASPIAN REGION

Abstract

The chemical composition of low molecular weight organic compounds (NOS) was studied by chromatography-mass spectrometric analysis of Populus nigra L. kidneys. Of the Caspian region and comparative antimicrobial (bactericidal) activity of extractive components with other plants with characteristic antimicrobial properties. The extraction was carried out by percolation in water-alcohol solutions. The study of antimicrobial activity was carried out by the standard CFU method. As a result, 49 compounds were identified, of which 10 remained unidentified. The study of comparative antimicrobial properties of plant extracts showed the complete bactericidal activity of Populus nigra kidneys against opportunistic microorganisms and microflora of air and water, in MIC equal to 0.25 micrograms/ml. Therefore, the NOSES isolated from the kidneys of Populus nigro of the Caspian region have prospects for further study of antioxidant activity for the preparation of biotechnological drugs and pharmaceutical substances.
