“…The sample amount (g), LOD, LOQ and recovery (analytical performance) were considered to demonstrate the advantages of the QuEChERS-dSPE/UHPLC-PDA method here validated. Overall, the current analytical methods proposed here used the lower sample amount (1 g), with the exception of the UADLLME/HPLC-UV method [31]. Nevertheless, the UADLLME/HPLC-UV method requires large volumes of solvents.…”

Insecticides are broadly applied in agriculture to defend crops from illnesses and pest attacks, consequently guaranteeing high production. However, their residual deposits in food products are becoming a main concern with regard to human consumption. As such, sensitive analytical methods should be developed to assess, prevent and control insecticide residues. In this research, an accurate, fast and reliable residual analytical method, that is quick, easy, cheap, effective, rugged and safe, combined with dispersive solid phase extraction (QuEChERS-dSPE), was developed for the determination of the most common insecticides used in potatoes cultivation (chlorpyrifos, λ-cyhalothrin, deltamethrin and acrinathrin), using an ultra-high performance chromatography photodiode array detector (UHPLC-PDA). The most influential extraction and instrumentation parameters that affect the method’s performance, such as extraction solvent, ratio salts, sorbents, stationary phases, gradient conditions and eluents, were assessed. Under the ideal conditions, good linearity (0.992–0.998), limits of detection (0.02–0.47 µg/kg) and quantification (0.06–1.58 µg/kg), recovery (94.1 to 112%) and precision (relative standard deviation <18%) were achieved for spiked levels between 2.5 and 50 µg/kg. The obtained results revealed that the potatoes analyzed do not represent any concern for human healthy, as the insecticide residues detected were lower than the maximum residue limits set by the European Union, Codex Alimentarius, and other organizations.

In this research, a novel method—namely vortex‐assisted emulsification microextraction—was introduced for the determination of pyrethroids (flucythrinate, beta‐cypermethrin, and fenvalerate) in mushrooms (Agaricus bisporus, Lentinula edodes, Auricularia auricular, and Flammulina velutiper). A green solvent 1‐dodecanol was used as the extraction solvent. The low freezing point makes 1‐dodecanol easy to solidify and separate after retention in an ice bath. To avoid the use of dispersion solvents, vortex agitation was applied instead to increase the contact area between extraction solvent and samples. The type and volume of extraction solvent, time of extraction, and addition of sodium chloride were optimized. Under optimal conditions, linear responses were obtained within 1–100 μg/g (R2 ≥ 0.999). The extraction recovery was within 70.2–89.2% with relative standard deviations of less than 8.1%. This method was simple, fast, and environmentally friendly, and was successfully applied to extract and analyze pyrethroids in Agaricus bisporus, Lentinula edodes, Auricularia auricular, and Flammulina velutiper.

“…The extraction yield of traditional Chinese medicines is affected by numerous factors, including the extraction temperature, time, solvent concentration, solvent-to-material ratio, pH value, ultrasonic power, particle size, and the ultrasonic extraction [45]. The temperature, extraction time, solvent-to-material ratio, and extraction power were selected as variables based on the single-factor experiments.…”

An evaluation of the ultrasonic extraction process and the antioxidant activities of hydroxysafflor yellow A (HSYA) and anhydrosafflor yellow B (AHSYB) from safflower are presented herein. Using response surface methodology (RSM), based on a four-factor-three-level Box–Behnken design (BBD), the extraction parameters, namely, temperature, extraction time, solvent-to-material ratio, and extraction power, were optimized for maximizing the yields of HSYA and AHSYB. The maximum yield was obtained at a temperature of 66 °C with an extraction time of 36 min, solvent-to-material ratio of 16 mL/g, and the extraction power of 150 W, which was adjusted according to the actual conditions. The HSYA and AHSYB contents were determined using high performance liquid chromatography (HPLC). The yield and the comprehensive evaluation value of HSYA and AHSYB were calculated. The antioxidant activities of the extracts were determined using a ferric reducing antioxidant power (FRAP) kit and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity. The results suggested that the safflower extracts possessed obvious ferric reducing and DPPH radical scavenging activities. The antioxidant activity increased with increasing concentration. The results suggested that optimizing the conditions of ultrasonic extraction using RSM can significantly increase the yields of HSYA and AHSYB from safflower. The safflower extracts showed better antioxidant activity. This study can encourage future research on cardiovascular and cerebrovascular diseases.
