Abstract: Essential oils are volatile compounds extracted from the flowers, leaves, rhizome, bole of plants. It was composed of secondary metabolites such as terpenes, phenols, alcohols and aldehydes etc. Essential oils are widely applied in food, medicine and other fields because of their broad-spectrum of antibacterial activity. In recent years, the antibacterial mechanism of essential oil and its components against pathogenic microorganisms was mainly studied. These researches demonstrated that essential oils and their components may have multiple targets for the inhibition of pathogenic microorganisms, including cell wall, cell membrane, DNA, etc. In this paper, the antibacterial mechanism of plant essential oils and their components against pathogenic microorganisms was reviewed, which provide basis for the research and application of them.

Key words: essential oils, pathogenic bacteria, antimicrobial, mechanism
