“…To form the ATPS, the concentrations of ethanol and salt were selected from above the curve of the phase diagram. Because of the mutual exclusion of salt ions and ethanol, the ions are excluded from the region near the surface of the ethanol in solution . As the concentration of ethanol or salt increased, the extent of the exclusion also increased.…”

An efficient ultrasound-assisted aqueous two-phase extraction and enrichment process for phenylethanoid glycosides from Cistanche deserticola Y. C. Ma stems was developed in this work. An ethanol/ammonium sulfate system was chosen for the aqueous two-phase system due to its fine partitioning and recycling behaviors. Single-factor experiments and response surface methodology were used to optimize the process parameters of the ultrasound-assisted aqueous two-phase extraction. The optimal conditions were as follows: a salt concentration of 23.5%, an ethanol concentration of 20%, an extraction time of 37 min, an extraction temperature of 30°C, a liquid/solid ratio of 30:1 w/w, and an ultrasound power of 300 W. Under the above conditions, the extraction yields of echinacoside and acteoside (the main components of phenylethanoid glycosides) reached 5.35 and 6.22 mg/g dry material weight, respectively. The contents of echinacoside and acteoside in the extracts reached 27.56 and 30.23 mg/g, respectively, which were 2.46- and 2.58-fold higher than the amounts obtained in ultrasound-assisted extraction. In conclusion, ultrasound-assisted aqueous two-phase extraction was an efficient, ecofriendly, and economical method, and it may be a promising technique for extracting and enriching bioactive components from plants.

“…As a green extraction technique, the use of aqueous two-phase systems (ATPSs) 15 has been widely applied for separation and enrichment of amino acids, 16 nucleic acids, 17 viruses, 18,19 proteins, 20 natural substances [21][22][23] and antibiotics. [24][25][26] ATPSs have several advantages, including that they are easily operated and have short handling time, higher enrichment factors and low equipment requirements. Therefore, the use of ATPSs is a suitable pretreatment method for environmental samples prior to HPLC analysis.…”

BACKGROUND Fluoroquinolone antibiotics and their metabolites can accumulate in soil and water. Trace amounts of fluoroquinolone antibiotic residues in the environment necessitate the pretreatment of samples prior to analysis. In this work, a polyoxyethylene cetyl ether (POELE20)–NaH2PO4 aqueous two‐phase system (ATPS) was combined with high‐performance liquid chromatography (HPLC) to separate and determine trace quantities of ciprofloxacin (CIP), norfloxacin (NRF) and pefloxacin (PEF) in environmental samples. RESULTS Single‐factor, multi‐factor, reproducibility and accuracy experiments were performed. The extraction efficiencies and enrichment factors for the three antibiotics were above 90 and 13.8%, respectively, under optimal conditions. The recovery efficiency of CIP was 92.08–99.50%, with a relative standard deviation (RSD) of 0.60–6.34%, and the recovery efficiency of NRF and PEF was 93.40–99.30%, with RSD of 0.98–5.16%, when this method was applied to spiked water and soil samples. The RSDs of intra‐ and inter‐day analyses were 1.56–3.42 and 1.33–3.97%, respectively. CONCLUSIONS This study demonstrated that POELE20–NaH2PO4 ATPS coupled with HPLC was suitable for the simultaneous separation, concentration and determination of trace quantities of CIP, NRF and PEF in environmental samples. Moreover, this method can be applied for the determination of trace fluoroquinolone antibiotics in food samples. © 2019 Society of Chemical Industry

Nowadays, the ATPSs mainly divides into the following four kinds: the polymer-polymer ATPSs (Li & Cao, 2010), polymer-salt ATPSs (Zafarani-Moattar & Hosseinpour-Hashemi, 2012), ion liquid-salt ATPSs (Han et al, 2012) and micromolecule alcohol-salt ATPSs Zafarani-Moattar, Nemati-Kande, & Soleimani, 2012).…”
