There is a myriad of secondary metabolites derived and isolated from various plants. In most cases the biological role of these compounds is not really known. However, they represent a treasure trove of chemistry that can be of both interest and benefit to humans. Essential oils are aromatic, oily liquids extracted from different plant parts. They occur during secondary metabolism, and are normally formed in special cells or cell groups or in glandular hairs found on many leaves and stems. Chemically, a single volatile oil comprises of up to 200 different constituents of terpenoid and non-terpenoid origin, which are synthesized through different biosynthetic routes with distinct primary metabolic precursors. Terpenoids are extremely variable ingredients with different carbon skeletons and a wide variety of oxygenated derivatives; they have gained a particular importance in the synthesis of novel drugs. Phenylpropanoid derivatives are the other important constituent; they are a promising class of bioactive molecules. Essential oil composition varies considerably because of both intrinsic (sexual, seasonal, ontogenetic, and genetic variations) and extrinsic (environmental and ecological aspects) factors. Moreover, it changes in different plant organs and such polymorphisms can also be found between individual plants of a distinct species. Furthermore, the chemical composition depends on the stage of plant development. All these variations may result in the expression of different metabolic pathways, and consequently, quantitative and qualitative variations may occur, leading to the definition of new chemotypes.
This Special Issue welcomes original research and reviews on essential oil extraction methods associated with chemistry and related bioactivities fields. The focus is on the variability of composition in relation to various factors, such as climatic or harvest time, nutritional status, or the isolation method used. New aspects of analysis, chemical characterization, and advancement in the extraction methods are of particular interest, as well as machine learning or artificial intelligence algorithm applications that study the composition–bioactivity correlation.
