COMPARATIVE CHARACTERISTICS OF THE CHEMICAL COMPOSITION AND BIOLOGICAL ACTIVITY OF EXTRACTS OF SULFURIC HUMIC ACID (AZOV REGION, KRASNODAR REGION)
The chromatography-mass spectrometry of toluene, chloroform, acetone and ethanol extracts of humic acids of sapropel of the Azov floodplain, the Krasnodar Territory was performed for the first time. The compounds determining the structural-group composition of each extract were identified and quantified. Mass spectra and structural formulas of compounds were obtained. A comparative analysis of the chemical composition of the extracts, biotesting using yeast dough and various strains of microorganisms, allowed to reveal the relationship between the specific features of the structure of the extract compounds and their physiological activity.
