TL;DR: The antimicrobial activity of essential oils is due to their solubility in the phospholipid bilayer of cell membranes, and terpenoids which are characterized by their lability have been found to interfere with the enzymes of energy metabolism.
Abstract: The solubility in water of essential oil constituents is directly related to their ability to penetrate the cell walls of a bacterium or fungus. The antimicrobial activity of essential oils is due ...

TL;DR: Oils that exhibited high antimicrobial properties and the broadest range of inhibition included cinnamon bark, lemongrass, and Roman chamomile, which showed a high degree of inhibition against both phage types, while 8 oils showed no inhibition against either phage.
Abstract: The purpose of this study was to examine the inhibitory effect of essential oils against a broad spectrum of microorganisms including bacteria, yeast, molds, and two bacteriophage. The inhibitory effects of 45 oils on eight bacteria (four Gram positive and four Gram negative), two fungi, and one yeast were examined using the disk assay method. Phage inhibition was measured by mixing the oils with a phage suspension, incubating the mixture at 4°C for 24 h, then plating on a lawn of indicator bacteria and assaying for plaque production. Of the oils tested, all oils exhibited inhibition over activity relative to controls. However, a number exhibited only weak inhibition against several gram positive bacteria. Gram negative bacteria were generally more resistant than Gram positive bacteria to oil treatment with Pseudomonas aeruginosa being the most resistant bacteria. Only cinnamon bark (Cinnamomum zeylanicum) and tea tree (Melaleuca alternifolia) oils showed an inhibitory effect against all the test...

TL;DR: The essential oils obtained from five commercial samples of Sicilian aromatic plants, laurel, sage, oregano, rosemary and coriander were analyzed by GC/MS and assayed for their antibacterial, antifungal and antioxidant activities.
Abstract: The essential oils obtained from five commercial samples of Sicilian aromatic plants, laurel, sage, oregano, rosemary and coriander were analyzed by GC/MS and assayed for their antibacterial, antifungal and antioxidant activities Twenty-five different genera of bacteria and one fungal species were used in this study as test organisms The oils showed a high degree of inhibition against all the microorganisms tested The highest and broadest activity was shown by the oil of oregano, while the oil of sage was the least effective The antioxidant activity of the oils was measured by the modified Thiobarbituric Acid Reactive Species (TBARS) assay, using egg yolk and rat liver as oxidable substrate, in absence and in presence of the radical inducer 2,2'-azobis (2-amidinopropane) dihydrochloride (ABAP) The activities were compared with those of α-tocopherol and 2,6-di-tert-butyl-4-methylphenol (BHT, butylated hydroxytoluene) The oils showed different effectiveness, the oregano oil being endowed with

TL;DR: The bioactivity of essential oils and their flavor and fragrance components have been known since ancient times and become increasingly important in the search for natural and safe alternative medicines in recent years.
Abstract: The bioactivity of essential oils and their flavor and fragrance components have been known since ancient times. Essential oils are a mixture of numerous compounds characterized by an essence of aromatic plants. Currently, approximately 3000 essential oils are known, 300 of which are commercially important, in particular for the pharmaceutical, food, household and cosmetic industries. Essential oils have been known to have various bioactivities including antibacterial, antiviral, anti-inflammatory, antifungal, antimutagenic, anticarcinogenic, and antioxidant as well as other miscellaneous activities. Consequently, studies on the biological activities of essential oils have become increasingly important in the search for natural and safe alternative medicines in recent years. This review discusses various biological activities of essential oils and their components that have been reported in scientific references.

TL;DR: The mechanism of the antimicrobial action of orégano and clove essential oils was studied simultaneously with two phenolic components, namely thymol and eugenol and revealed that both cell wall and membrane of the treated bacteria were significantly damaged.
Abstract: The mechanism of the antimicrobial action of oregano (Origanum compactum) and clove essential oils was studied simultaneously with two phenolic components, namely thymol and eugenol. Escherichia coli and Bacillus subtilis were used as Gram negative and Gram positive bacterial models, respectively. The oils as well as their major components were capable of inducing cell Iysis. Bacteria Iysis was shown by the release of substances absorbing at 260 nm. For E. coli, the results were similar to those obtained with polymyxin B. Scanning electronic microscope observations revealed that both cell wall and membrane of die treated bacteria were significantly damaged.
