Preparing a sample for analysis is a crucial step of many analytical procedures. The goal of sample preparation is to provide a representative, homogenous sample that is free of interferences and compatible with the intended analytical method. Green approaches to sample preparation require that the consumption of hazardous organic solvents and energy be minimized or even eliminated in the analytical process. While no sample preparation is clearly the most environmentally friendly approach, complete elimination of this step is not always practical. In such cases, the extraction techniques which use low amounts of solvents or no solvents are considered ideal alternatives. This paper presents an overview of green extraction procedures and sample preparation methodologies, briefly introduces their theoretical principles, and describes the recent developments in food, pharmaceutical, environmental and bioanalytical chemistry applications.

“…For lipophilic azo dyes such as Sudan dyes, the solvents of methanol or acetonitrile and water or 0.1% (v/v) formic acid aqueous solution often serve as the mobile phase (66-68). However, for ionic azo dyes, the pH of the mobile phase has to be controlled by using ammoniaammonium acetate or other buffers because it can significantly affect chromatographic separation in several ways, such as selectivity, peak shape, and retention (45).…”

“…In order to improve selectivity of SPE, a large number of new materials are introduced as SPE adsorbents for the detection of inedible azo dyes in foods, such as molecularly imprinted polymers (MIPs) and magnetic nanoparticles (43)(44)(45). Yu and coworkers (46) reported a magnetic solid-phase extraction method with the nanocomposites of polystyrene-coated magnetic nanoparticles as the adsorbent for the extraction of four Sudan dyes (I-IV) in red wines, juices, and mature vinegars.…”

Edible colorants, as an important part of food additives, can not only enhance the sensorial attributes of foodstuffs, but can also increase one's appetite. They hold a very important position in food processing. In the past decades, the illegal addition of the inedible colorants has become one of the major issues of food safety. Industrial dyes, especially some azo dyes, are illegal additives frequently found in foodstuffs. They cannot provide any nutrients for the human body and even have toxicity, carcinogenic, or mutagenic effects, which may cause serious damage to consumers' health. There is an increasing demand to detect the inedible azo dyes in foodstuffs for health and safety reasons. In this review, the types and the physicochemical properties of the inedible azo dyes adulterated in foodstuffs and beverages are summarized, and the emphases are focused on the sample pretreatment methods and analytical techniques for monitoring of these dyes in foodstuffs and beverages.

“…Generally, the adsorbents based on mixed hemimicelles (hemimicelle and/or admicelle) formed on the surface of alumina, silica, and titanium oxides are packed in conventional SPE cartridge, and tedious sample loading, cleaning, and eluting processes with large consumption of adsorbents and organic solvents are often performed . Compared with traditional sorbents, magnetic nanoparticles possess strong superparamagnetism properties and large surface area which can provide high adsorption capability, rapid extraction and separation from the sample solution by applying a strong magnetic field in a batch system . So, in recent years, magnetic mixed hemimicelle SPE has been widely used for the extraction and preconcentration of various analytes, such as pharmaceuticals , bioactive constituents , herbicides , phenolic pollutants , and food colorants .…”

A novel dispersive admicelle solid-phase extraction method based on sodium dodecyl sulfate-coated Fe O nanoparticles was developed for the selective adsorption of berberine, coptisine, and palmatine in Gegen-Qinlian oral liquid before high-performance liquid chromatography. Fe O nanoparticles were synthesized by a chemical coprecipitation method and characterized by using transmission electron microscopy. Under acidic conditions, the surface of Fe O nanoparticles was coated with sodium dodecyl sulfate to form a nano-sized admicelle magnetic sorbent. Owing to electrostatic interaction, the alkaloids were adsorbed onto the oppositely charged admicelle magnetic nanoparticles. The quick separation of the analyte-adsorbed nanoparticles from the sample solution was performed by using Nd-Fe-B magnet. Best extraction efficiency was achieved under the following conditions: 800 μL Fe O nanoparticles suspension (20 mg/mL), 150 μL sodium dodecyl sulfate solution (10 mg/mL), pH 2, and vortexing time 2 min for the extraction of alkaloids from 10 mL of diluted sample. Four hundred microliters of methanol was used to desorb the alkaloids by vortexing for 1 min. Satisfactory extraction recoveries were obtained in the range of 85.9-120.3%, relative standard deviations for intra- and interday precisions were less than 6.3 and 10.0%, respectively. Finally, the established method was successfully applied to analyze the alkaloids in two batches of Gegen-Qinlian oral liquids.
