Аннотация: The article presents the results of studying the antibacterial activity of fir tree and Siberian spruce bark water extracts. As test objects, pathogenic (3-4 hazard class) and saprotrophic bacteria were used. It has been shown that the studied aqueous extracts of dark-coniferous bark do not exhibit biocide activity against the condПоказать полностьюitionally pathogenic bacterium Escherichia coli. However, all the other studied bacteria are sensitive to the extracts analyzed both on day 3 and day 13. At the same time, the aqueous extract of the Siberian fir bark has a higher biocide activity against conditionally pathogenic and saprotrophic bacteria in comparison with the aqueous extract of the Siberian spruce bark. The antibacterial activity of aqueous extracts of the studied plants bark is determined by their chemical composition, primarily the presence of substances of a phenolic nature. It has been shown that the studied extracts mainly contain compounds of quercetin, dihydroquercetin and kaempferol.
