Separation and Detection of Essential Oil

Dear Colleagues,

After years of fascination with foods or pharmaceuticals, the composition of which was dominated by synthetic chemical substances, often not occurring in nature, we are now observing a reverse trend leading to the use of natural plant materials. Essential oils are one of the interesting groups of biologically active compounds found in plants. Essential oils are usually produced as secondary metabolites, and the place of their accumulation is the secretory structures present on the surface (secretory hairs) or placed inside the plant (secretory ducts). Essential oils are multicomponent mixtures of volatile chemical compounds extracted from plant tissues, mainly by steam distillation (in various variants). Other methods are also used that allow the isolation of volatile compounds as the dominant components in the complex of active substances. Essential oils have a broad spectrum of activity. Currently, essential oils are used in medicine, aromatherapy, in food production, and in cosmetics. The basis for the assessment and practical application of essential oils is to know their chemical composition, which involves a number of different procedures consisting of isolation, identification, and quantitative analysis.

This Special Issue will be focused the following topics: the separation of essential oils from plant material using various methods, including support with ultrasound and microwave techniques (extraction, steam distillation, aroma recovery, supercritical fluid, headspace, fractionation, solid phase microextraction (SPME), stir bar sorptive extraction (SBSE), solvent-assisted flavor evaporation (SAFE)), identification of individual components of essential oils (identification, quantification, mass spectrometry, NMR, HPLC, UPLC, GC, MDGC, comprehensive GCxGC, GC-FID, GC-MS, GC-FTIR, LC-MS, GC-olfactometry, TLC, chiral separation, natural product authentication, isotopic analysis, stable isotope ratios analysis (SIRA)), quantitative analysis of the components of essential oil, and chemical composition of some aromatic plants.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Separations is an international peer-reviewed open access monthly 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 2600 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.
