Abstract

Deep eutectic solvents (DESs) and ionic liquids have been considered organic solvents and applied in numerous chemical procedures. DESs usually are produced by combining 2 or 3 organic components. DES can be formed in a mixture by combining hydrogen bond donors like urea, polyols, and carboxylic acids with hydrogen bond acceptors. In the present study, deep eutectic solvents as a green solvent -minimized extraction method known as Headspace-solvent microextraction was established. Methods: Deep eutectic solvents hydrodistillation single drop microextraction (DES-HS-SDME) was presented for extracting essential oils compounds through DESs as extraction solvents prepared via combining choline chloride and p-Chlorophenol. They were used to extract volatile compounds from Satureja hortensis L. leaves. To avoid the time-consuming and traditional hydrodistillation, the volatile components in Satureja hortensis L.’s aerial parts were analyzed through a simple distillation with headspace single-drop microextraction along with gas chromatography. According to the experimental findings, DESs-HS–SDME is a rapid, low-cost, simple, and reliable technique to determine volatile fractions in Satureja hortensis L.
