The article presents the results of studying the antibacterial activity of fir tree an 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 darkd coniferous bark do not exhibit biocide activity against the conditionally pathogenic bacterium- Escherichia coli. However, all the other studied bacteria are sensitive to the extracts analyze both on day 3 and day 13. At the same time, the aqueous extract of the Siberian fir bark has d higher biocide activity against conditionally pathogenic and saprotrophic bacteria ina comparison with the aqueous extract of the Siberian spruce bark. The antibacterial activity o aqueous extracts of the studied plants bark is determined by their chemical compositionf 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.
