Abstract. Increasing antibiotic resistance threatens the effectiveness of antibiotics. They are becoming ineffective and infections are difficult or impossible to treat. As a result, one of the current trends that aims to address the emerging problem is the search for herbal medicines that have some antimicrobial activity. The object of the study were extracts and oils obtained from different fractions (roots, leaves, stems, whole plant) of six plant species (mint, lavender, thyme, oregano, basil, coriander) using different solvents (water, ethanol, vinegar, wine, olive oil) grown under greenhouse conditions and statistical processing of the obtained 360 databases on their antimicrobial activity against Escherichia coli. The results of the conducted complex studies are a good basis for the introduction of practically applicable technologies for the production of extractive solutions with high antimicrobial activity against Escherichia coli.
