“…[5,6] Generally, the predominant constituent of plant essential oils are isoprenoids, which are extracted from different plant parts by distillation or other advanced methods. [7][8][9] Essential oils are extremely complex in composition due to the presence of highly functionalized chemical substances of different chemical classes including monoterpenoids, sesquiterpenoids and phenylpropanoids. [6] More than 55,000 isoprenoids (also termed as terpenes or terpenoids) have been isolated with some being characterized for diverse functional roles, and their number doubles in each decade.…”

In aromatic plants species, biosynthesis of essential oils oocurs through two complex natural biochemical pathways involving different enzymatic reactions. Isopentenyl diphosphate (IPP) and its isomer dimethylallyl diphosphate (DMAPP) are the universal precursors of essential oils biosynthesis and are produced by the cytosolic enzymatic MVA (mevalonic acid) pathway or by plastidic and enzymatic 1-deoxy-D-xylolose-5-phosphate (DXP), also called the 2-Cmethylerythritol 4-phosphate (MEP) pathway. In the particular plant cell part, prenyl diphosphate synthases condense isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP) further to form prenyl diphosphates, which are used as substrates for geranyl diphosphate, C 10 (GPP) or for fernesyl diphosphate, C 15 (FPP). Essential oils are final terpenoid products and are formed by a huge group of enzymes known as terpene synthases (TPS). Essential oils are important secondary metabolites of plants and have been used not only in different industries but also in ethnobotanical medicines for centuries. Hence, considerable research has been undertaken to understand the essential oils biosynthetic pathways. This review will be a valuable source of information in the field of natural products as we give detailed insights about biosynthesis of essential oils in plants, and thus indicate also new unexplored horizons for further research.

“…MAE is also one of the best green technologies and has emerged as an efficient method for extracting several natural products, contaminants, additives, etc. [17][18][19][20][21][22][23]. In recent years, MAE has been applied to the extraction of several types of compounds, such as phenolic products from alperujo [24], additives in polyolelfins and polymers [25], diterpenes in green coffee oil [26], triterpenes and biophenols in olive leaves [27][28][29][30], polychlorinated biphenyls in foods and soils [31], and oleanolic acid (OA) in Lantana camara [32].…”

Microwave-assisted extraction versus Soxhlet extraction to determine triterpene acids in olive skins

et al. 2017

Microwave-assisted extraction is compared with a more classical technique, Soxhlet extraction, to determine the content of triterpene acids in olive skins. The samples used in their original unmilled state and milled were extracted with ethyl acetate or methanol as solvents. The optimized operating conditions (e.g., amount and type of solvent, and time and temperature of extractions) to attain the better extraction yields have been established. For the identification and quantitation of the target compounds, an ultra high performance liquid chromatography with tandem mass spectrometry method was employed. The best results were achieved using the microwave-assisted extraction technique, which was much faster than the Soxhlet extraction method, and showed higher efficiency in the extraction of the triterpenic acids (oleanolic and maslinic).

“…For the development of an on‐line SFE–GC coupling five basic steps should be considered, as follows : Extraction of analytes by the supercritical fluid. Depressurization of the supercritical fluid. Trapping and transfer of the (trapped) analytes into a GC column or injector. Focusing of the transferred analytes. Gas chromatographic separation of the analytes. …”

“…For the development of an on-line SFE-GC coupling five basic steps should be considered, as follows [18,21]: The first step is the extraction of the analytes, which means the optimization of the SFE sample preparation as described in Section 2. Then, the second and third steps are the depressurization and trapping steps, which require a special interface.…”

This review summarizes and discusses recent advances and applications of on-line supercritical fluid extraction coupled to liquid chromatography, gas chromatography, and supercritical fluid chromatographic techniques. Supercritical fluids, due to their exceptional physical properties, provide unique opportunities not only during the extraction step but also in the separation process. Although supercritical fluid extraction is especially suitable for recovery of non-polar organic compounds, this technique can also be successfully applied to the extraction of polar analytes by the aid of modifiers. Supercritical fluid extraction process can be performed following "off-line" or "on-line" approaches and their main features are contrasted herein. Besides, the parameters affecting the supercritical fluid extraction process are explained and a "decision tree" is for the first time presented in this review work as a guide tool for method development. The general principles (instrumental and methodological) of the different on-line couplings of supercritical fluid extraction with chromatographic techniques are described. Advantages and shortcomings of supercritical fluid extraction as hyphenated technique are discussed. Besides, an update of the most recent applications (from 2005 up to now) of the mentioned couplings is also presented in this review.
