deep eutectic solvents as an efficient solvent system determination the volatile compounds with microextraction

In the present work, the headspace-solid phase microextraction (hs-sdme) process was established utilizing a novel version of deep-eutectic-solvents (dess) for extracting and preconcentrating essential oils in plants followed by gc-fid determination. dess seem to be a cost-effective and attractive alternative for the usage of ionic solvents in biotransformation. dess are usually developed through gentle warming and stirring of two (low-cost and bio-based) salts. dess have several superiorities over ionic liquids such as their ease of preparation, low production cost, and permit for large-scale applications. hs-sdme was made in the current research in order to extract volatile compounds by the use of deep eutectic solvents (dess) serving as extraction solvents. hs-sdme was constructed as a solvent-minimized extraction method. however, there are a rare number of studies investigating the deep eutectic solvents (dess) applications to the hs-sdme of bioactive compounds. deep eutectic solvents, created by mixing choline chloride (chcl) and p-chlorophenol at varying ratios were utilized for extracting essential oils from echinophora platyloba dc via hs-sdme in the present study. afterward, headspace single-drop micro-extraction (hs–sdme) was conducted, being connected to gas chromatography. hs-sdme is a quick and simple method in comparison with heat reflux extraction. in addition, it is possible to use dess in hs-sdme for extracting various volatile compounds.
