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 bacteriumEscherichia 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.
