“…Therefore, the development of a new alternative green extraction technique and the search for alternative solvents are imperative [4]. Until recently, the research has been focused on ionic liquids (ILs) as an extraction medium due to their unique properties, such as density, viscosity, hydrophilicity or hydrophobicity and solubility, which could be adjusted by the selection of an appropriate cation and anion [5,6]. Beside mention advantages for ILs, due to high price, tedious synthesis routes, need for further purification of the synthesized ILs and toxicity of some cases lead to limitation of their extensive applications [7].…”

A green, simple and sensitive hydrophobic DES-based dispersive liquid–liquid microextraction coupled with high-performance liquid chromatography (HPLC) was developed for the analysis of neonicotinoid insecticide residues in various samples. A hydrophobic deep eutectic solvent (DES) was synthesized using decanoic acid as a hydrogen bond donor and tetrabutylammonium bromide (TBABr) as a hydrogen bond-acceptor. DESs were synthesized and characterized by Fourier transform-infrared (FTIR) spectroscopy. Two disperser solvents were substituted with surfactants and acetonitrile, which could afford more effective emulsification and make the extraction relatively greener. The hydrophobic DES extraction phase occurred 10 min after centrifugation, being easy to be collected for analysis. Several parameters were investigated and optimized. Under the optimum condition, the calibration curve of this method was linear in the range of 0.003–1.0-µg·mL−1, with a correlation coefficient (R2) higher than 0.99 and a good repeatability, with the relative standard deviations (RSDs) were less than 5.00%. The limits of detection were in the range of 0.001–0.003 µg·mL−1; the limits of quantitation were in the range of 0.003–0.009 µg·mL·mL−1. Finally, the presented method was implemented to determine the neonicotinoid insecticide residues in water, soil, egg yolk samples and acceptable recoveries were obtained.

“…A few common adsorbents have been successful applied in the crucial adsorbing process, such as silica (Labadie, Alliot, Bourges, Desportes, & Chevreuil, ), SBA (Cao et al, ) and Florisiol (Celeiro et al, ). However, limited studies have investigated about modified β‐CD which was only used as adsorbent for the determination of isomers in plants (Xu, Wang et al, ), while organic methanol was employed as eluent.…”

“…At present, several researches such as mixed cloud point extraction (Zhou et al, ), sea sand disruption method (Wianowska, Typek, & Dawidowicz, ), solid‐phase extraction (Xu, Wang et al, ), miniaturized matrix solid phase dispersion procedure, and solid‐phase microextraction (Moliner‐Martinez, Campíns‐Falcó, Molins‐Legua, Segovia‐Martínez, & Seco‐Torrecillas, ) for extracting the target active compounds from samples have been reported. According to its capacity of rapidity, flexibility, multifunctionality, feasibility, and low costs (Barker, ), the matrix solid‐phase dispersion extraction (MSPDE) has been used in different fields of extraction including polybrominated diphenyl ethers in Human Placenta (Dassanayake, Wei, Chen, & Li, ), large‐scale pesticide testing (Gilbert‐López, García‐Reyes, Lozano, Fernández‐Alba, & Molina‐Díaz, ), hormones in milk (Gañan, Silva, Morante‐Zarcero, Pérez‐Quintanilla, & Sierra, ), biota fruits (Moliner‐Martinez, Campíns‐Falcó, Molins‐Legua, Segovia‐Martínez, & Seco‐Torrecillas, ), raw propolis (Wang et al, ), and Chinese herbs (Liu et al, ; Shi et al, ).…”

A simple miniaturized matrix solid‐phase dispersion extraction was developed to analyze multiple antioxidant ingredients (neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, rutin, isoquercitrin, and astragalin) in Mori Fructus by ultra performance liquid chromatography coupled with an ultraviolet detector. 1‐ethyl‐3‐methylimidazolium bromide was employed in the elution process as eco‐friendly elution solvent. The effects of some factors on the extraction efficiency of antioxidants in Mori Fructus were optimized in detail, such as the type of adsorbent, the type of elution solvent, the concentration and volume of elution solvent, sample to adsorbent ratio, and the grinding time. The intra‐day and inter‐day precisions (RSD) were both below 5.0% and the recoveries of all analytes ranged from 93.5% to 98.3%. Compared with the traditional method, it was efficient, simple and environment‐friendly for extracting the analytes by ionic liquid assisted trace β‐CD matrix solid‐phase dispersion extraction method, due to shorter extraction time, less reagent and less sample consumption. The developed method was successfully used for extracting and determining the active compounds in Mori Fructus sample. Practical applications The antioxidant ingredients play important roles in Mori Fructus because of their main pharmacological activities. Nowadays, a few analytical methods could be applied for extracting and analyzing these target compounds. But these methods not only required much extracting and analyzing time, but also need a great deal of organic reagent, which were not environmentally friendly. Thus, a green and simple miniaturized matrix solid phase dispersion extraction method was proposed for the analysis of these antioxidants in Mori Fructus, which was efficient to be employed for evaluating the quality of Traditional Chinese Medicine.

“…It is therefore necessary to separate and concentrate the targeted analytes from the matrix sample to improve the detection sensitivity [ 10 ]. Many papers have reported enrichment methods including free air carbon dioxide enrichment (FACE) [ 11 ], cloud point extraction (CPE) [ 12 ], ionic liquid/ionic liquid liquid-liquid microextraction [ 13 ], solid-phase extraction (SPE) [ 14 ], and aqueous two-phase system (ATPS) [ 15 ]. The micelle-mediated extraction and cloud point preconcentration method provide a suitable alternative to the common extraction methods [ 16 ].…”

A simple cloud point preconcentration method was developed and validated for the determination of gallic acid, bergenin, quercitrin, and embelin in Ardisia japonica by high-performance liquid chromatography (HPLC) using ultrasonic assisted micellar extraction. Nonionic surfactant Genapol X-080 was selected as the extraction solvent. The effects of various experimental conditions such as the type and concentration of surfactant and salt, temperature, and solution pH on the extraction of these components were studied to optimize the conditions of Ardisia japonica. The solution was incubated in a thermostatic water bath at 60°C for 10 min, and 35% NaH2PO4 (w/v) was added to the solution to promote the phase separation and increase the preconcentration factor. The intraday and interday precision (RSD) were both below 5.0% and the limits of detection (LOD) for the analytes were between 10 and 20 ng·mL−1. The proposed method provides a simple, efficient, and organic solvent-free method to analyze gallic acid, bergenin, quercitrin, and embelin for the quality control of Ardisia japonica.
