“…Various extraction approaches have been used for this purpose, sometimes coupled with a sample clean up. These techniques involve water or organic solvent extraction, 20,23,25,52,75 the QuEChERS methodology, 67,68,71,72 reflux extraction, 51,58 extraction under stirring, 65 vortexing, 53 shaking on a rotary shaker, 19 as well as extraction assisted by auxiliary energy, such as microwave‐assisted extraction 42,43,64 and the most commonly used ultrasound‐assisted extraction. Application of auxiliary energies can intensify the mass transfer and thus improve the extraction efficiency.…”

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.

“…Specifically, IL used as extraction solvent, was successfully recovered by modifying the pH and it can be reused three times without any significant loss of extraction efficiencies. In addition, Sheikhian and Shirafkan [62] also successfully separated ILs from analytes by changing pH and reused ILs at least four times. These methods are capable of minimizing the cost of extraction solvents and the environment and safety issues.…”

Dispersive liquid-liquid microextraction (DLLME) is a novel sample preparation technique that has higher level of extraction efficiency by means of relying on microvolumes of solvents. It has gained considerable attention from researchers owing to several advantages such as its simplicity, shorter extraction time, lower cost and higher enrichment factor. In conventional DLLME, chlorinated solvents are widely used as the extraction solvents. Notwithstanding, most of these solvents are reportedly toxic and environmentally-unfriendly. Many related studies in recent years have focused on the use of nontoxic or low toxic extraction solvents and better practical procedures, which have helped improve the extraction efficiency. The aim of this review is to discuss the development of low toxic extraction solvent used recently in the DLLME. The possible improvement of extraction solvent from the green analytical chemistry perspectives is also discussed.Keywords: extraction solvents, dispersive liquid-liquid microextraction, green analytical chemistry Abstrak Pengekstrakan mikro cecair-cecair serakan (DLLME) merupakan teknik penyediaan sampel novel yang mempunyai lebih tinggi kecekapan pengekstrakan dengan menggunakan mikroliter pelarut. Teknik ini telah mendapat perhatian daripada penyelidik kerana beberapa kelebihan seperti ringkas, masa pengekstrakan yang lebih pendek, kos yang lebih rendah dan faktor pengayaan yang lebih tinggi. Dalam DLLME konvensional, pelarut berklorin digunakan secara meluas sebagai pelarut pengekstrakan. Namun, kebanyakan pelarut ini dilaporkan toksik dan tidak mesra alam. Dalam tahun kebelakangan ini, banyak kajian yang berkaitan telah fokus kepada penggunaan pelarut pengekstrakan yang tidak bertoksik atau rendah toksik dan praktikal prosedur yang lebih baik telah meningkatkan kecekapan pengekstrakan. Tujuan kajian ini adalah untuk membincangkan perkembangan pelarut pengekstrakan rendah toksik yang digunakan dalam DLLME terkini. Penambahbaikan pelarut pengekstrakan dari perspektif kimia analisis hijau juga dibincangkan.Kata kunci: pelarut pengekstrakan, pengekstrakan mikro cecair-cecair serakan, kimia analitik hijau
