Deep Eutectic Solvent as a Green Solvent for Fast Analysis of the Volatile Components of Satureja Hortensis L.

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.

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.
