“…The SOE system was developed for the extraction of bio‐based chemicals from fermentation broths, such as 1,3‐propanediol, 2,3‐butandiol, lactic acid, succinic acid, and so on. It was also widely used in the separation, concentration, and primary purification of various compounds, such as proteins, pesticides, herbicides, pharmaceutical molecules, natural active constituents, and so on. In recent years, more and more studies reported on the extraction and primary purification of active constituents from natural plant resources by SOE, such as the extraction of lutein from marigold flower, lithospermic acid B from Salvia miltiorrhiza Bunge, allicin from Allium sativum L., chlorogenic acid from Boehmeria nivea L. Gaud leaves, and crocins from Crocus sativus …”

BACKGROUND: The aqueous two-phase extraction (ATPE) based on organic solvent and inorganic salt was considered a promising method in the extraction, enrichment, and purification field. Ionic liquids (ILs) used as additives to the aqueous two-phase system (ATPS) can improve the extraction yield. RESULTS: In this study, sevenILs were added to the ethanol/ammonium sulfate ATPS and used for the salting-out extraction (SOE) of sinomenine from Sinomenium acutum. The IL [C 2 OHmim]FeCl 4 was screened as the optimal additive, then the influencing factors IL amount, ethanol concentration, salt concentration, and temperature were investigated. The maximum extraction efficiency of 96.4% was obtained under the following conditions: 23.06 wt% ethanol concentration, 27.28 wt% (NH 4 ) 2 SO 4 concentration, 4.0 wt% [C 2 OHmim]FeCl 4 and 40 ∘ C temperature. Moreover, the components in the SOE system can be recycled after extraction. CONCLUSION: Thus, this ATPS had lower cost and higher extraction ability, and it is feasible to scale up using a small amount of ILs. This system can also be used in the extraction of some other important active compounds from natural plant resources.

BACKGROUND Pesticides are extensively used worldwide to control plant pathogens and prevent agricultural product damage. However, they can pollute the environment and endanger human health. So far, a variety of sample preparation methods have been developed for the analysis of pesticide residues. RESULTS A hyphenated solid–liquid microextraction method based on a new adsorbent of magnetic graphene oxide functionalized by (3‐glycidyloxypropyl)trimethoxysilane and a deep eutectic solvent (choline chloride/4‐chlorophenol (1:2)) was developed for extraction/preconcentration of trace levels of pesticides. The sorbent was characterized using scanning electron microscopy, Fourier transform infrared spectroscopy, and vibrating sample magnetometry. In‐syringe magnetic dispersive solid‐phase extraction in tandem with dispersive liquid–liquid microextraction followed by gas chromatography was applied for the analysis of the selected pesticides. The main parameters governing sample preparation efficiency, including adsorbent dosage, desorption conditions, pH, extraction time, deep eutectic solvent volume, and salt concentration, were investigated. The linear ranges were 0.024–500 μg L−1 with 0.9971–0.9999 linearity factor (R2). The limits of detection and quantification were 0.006–0.038 and 0.024–0.126 μg L−1, respectively. The relative standard deviations were 0.5–4.2% for intra‐day analysis and 2.7–4.6% for inter‐day analysis. Enrichment factors were in the range 210–540. CONCLUSIONS The method was successfully applied for the determination of malathion, heptachlor epoxide, endrin, dichlorodiphenyltrichloroethane, azinphos ethyl, cypermethrin, and deltamethrin in fruit juice samples (apple, pineapple, cherry, peach, and red and green grape juices) and the recoveries were within the range 71–115%. © 2020 Society of Chemical Industry

In the present study, a simple and rapid method for the extraction and preconcentration of some polycyclic aromatic hydrocarbons in water samples has been developed. In this method, two sample preparation methods were combined to obtain high extraction recoveries and enrichment factors for sensitive analysis of the selected analytes. In the first stage of the method, a homogeneous solution containing an aqueous solution and cyclohexyl amine is broken by the addition of a salt. After centrifugation, the upper collected phase containing the extracted analytes is subjected to the following dispersive liquid-liquid microextraction method. Rapid injection of the mixture of cyclohexyl amine resulted from the first stage and 1,1,2-trichloroethane (as an extraction solvent) into an acetic acid solution is led to form a cloudy solution. After centrifuging, the fine droplets of the extraction solvent are settled down in the bottom of the test tube, and an aliquot of it is analyzed by gas chromatography. Under the optimum extraction conditions, enrichment factors and limits of detection for the studied analytes were obtained in the ranges of 616-752 and 0.08-0.20 μg/L, respectively. The simplicity, high extraction efficiency, short sample preparation time, low cost, and safety demonstrated the efficiency of this method relative to other approaches.
