“…SDME has been widely employed as a green microextraction technique for trace analysis in chemical, biological, food, environmental, clinical, pharmaceutical, and forensic analysis. Representative examples include analysis of Pd, Be, Co, and Cd in biological samples [160], methamphetamine in human plasma and urine [161], carbaryl and triazophos pesticides in fruit juice and water samples [162], organic compounds in environmental matrices [163], xylene, toluene, benzene, and ethylbenzene in water samples [164], essential oils in plants and herbs [165], accelerants of fire in fire debris samples [166], volatile organic compounds in water and air [167], phenol derivatives in dairy products and soft drinks and organophosphorus pesticides in juice [168].…”

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.

“…Conventional procedures for the extraction of a plant constituents usually require a relatively large amount of sample. In contrast, microextraction procedures typically work with lesser amounts of plant material, which can range from several tens of milligrams (10 mg, 14–16,37–39 20 mg, 40 40 mg, 31 50 mg 21,26,34,41,42 ) to one or several hundred milligrams (100 mg, 17,24,29,43–50 150 mg, 51 200 mg, 35,52 0.3 g, 32,53 0.4 g, 54 0.5 g, 25,28,55–60 0.6 g, 61 0.7 g, 62 0.750 g, 18 0.9 g 63 ). However, in some cases weights ranging from one 19,22,30,64–66 or more grams (2 g, 14,20,23,36,67–72 2.5 g 73 to 5 g 74 ) have also been used.…”

Introduction: The analysis of plant and herbal samples is a challenging task for analytical chemists due to the complexity of the matrix combined with the low concentration of analytes. In recent years different liquid-phase microextraction (LPME) techniques coupled with a variety of analytical equipment have been developed for the determination of both organic and inorganic analytes. Objective: Over the past few years, the number of research papers in this field has shown a markedly growing tendency. Therefore, the purpose of this review paper is to summarise and critically evaluate research articles focused on the application of LPME techniques for the analysis of plant and herbal samples. Results: Due to the complex nature of the samples, the direct application of LPME techniques to the analysis of plants has not often been done. LPME techniques as well as their modalities have been commonly applied in combination with other pretreatment techniques, including a solid-liquid extraction technique supported by mechanical agitation or auxiliary energies for plant analysis. Applications and the most important parameters are summarised in the tables. Conclusion: This review summarises the application of the LPME procedure and shows the major benefits of LPME, such as the low volume of solvents used, high enrichment factor, simplicity of operation and wide selection of applicable detection techniques. We can expect further development of microextraction analytical methods that focus on direct sample analysis with the application of green extraction solvents while fully automating procedures for the analysis of plant materials.

The present article offers a glance at achievements in single-drop microextraction(SDME), with a focus on the two most commonly used modes of this technique: headspace and direct immersion. Factors affecting SDME, such as the pH and ionic strength of the sample solution, the stirring rate, and the extraction time are briefly summarized. The requirements for the acceptor phase and the influence of the sampling temperature are presented. In addition, the potential of the application of microwave and ultrasonic energy in SDME is also discussed. Examples of the application of the headspace and direct immersion modes of SDME are given in a table as additional Supporting Information.
