Antibacterial and Biological Activity of Essential Oils: From In Vitro to In Vivo Evidence

Dear Colleagues,

Essential oils (EOs) and their compounds are one of the most “popular” and interesting agents among secondary plant metabolites. EOs are a mixture of volatile compounds, mainly mono- and sesquiterpenoids, phenylpropanoids, etc., and contain hundreds of individual chemical constituents, which may have biological activity. They are secreted in special cells in secretion ducts or cavities or in glandular hairs, from which they are extracted by distillation (water–steam or hydro–distillation) or pressing. Because of the spread of multidrug-resistant bacteria and their growing antibiotic-resistance, many research groups have focused their research on investigating the antimicrobial activities of EOs. Not only can nosocomial infections and antibiotic-resistance cause serious health problems, but they can also cause other diseases, such as neurological, cardiovascular, and respiratory diseases as well as cancer, etc., all of which affect a  large portion of the world’s population.

The aim of this Special Issue is to collect original research and critical reviews on antibacterial and biological activity and the mode of action of EOs and/or their compounds. Papers offering novel alternatives to antibiotics, new antibacterial therapies to control or prevent infections, or new solutions to treat inflammatory health conditions are welcome. Not only in vitro but also experimental or clinical studies that are focused on the antibacterial and/or biological activity of EOs or their pharmaceutical formulation are greatly encouraged.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the Special Issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
