“…Thus, it is crucial to perform the respective optimisation in order to obtain the good recovery. Because this optimisation has already been performed and published [24], in this work only final extraction conditions are presented. So it was found that 2 μL of p-xylene at 70°C for 90 s using 0.5 g of sample in a 10 mL sampling vial are suitable conditions for the HS-SDME method.…”

Abstract:The analytical microextraction methods of gas chromatography coupled with flame ionisation detector (GC-FID) for determination of selected essential oils in herbs were proposed. Two microextraction methods for the isolation of essential oils from plants such as Lavandula spica L., Melissa officinalis L., Mentha piperita L. and Salvia officinalis L. were used. The methods of solid-phase and single-drop microextractions, were optimised and compared. The obtained LOD values for all studied essential oils were found to be within 2.5-20.5 µg for SDME and 57.0-139.8 µg for SPME method per 100 g of dried sample leaves. The appropriate LOQ values were then 8.4-68.4 µg for SDME and 189.8-466.1 µg for SPME of target analytes per 100 g of dried sample leaves.© Versita Warsaw and Springer-Verlag Berlin Heidelberg.

“…Tea infusions are commonly prepared by simulating the conditions under which these infusions are prepared in everyday practice by steeping a packet of teas in boiling water for a prescribed period of time (5–15 min) 13,14 . Analyses based on the LPME technique have been reported using various parts of plant samples, including root, 15–18 stem, 16 leaf, 16,19,20 fruit, 16,21 leaves, 22–29 flowers 30–33 and seeds 34–36 …”

“…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.
