“…For the preparation of the foam, the MOF powder was dispersed in an acid solution containing chitosan, glutaraldehyde as crosslinking agent, and a gelatin, and afterwards the mixture was placed in a mold and freeze-dried to ensure formation the foam. The miniaturized versions of MSPD methods have also benefited from the incorporation of chitosan as dispersant [55,56]. In these strategies, the chitosan powder and the solid sample are mixed using a pestle to accomplish the extraction of the compounds.…”

Since the introduction of the Green Analytical Chemistry guidelines, there has been an increasing concern on the sustainability of sample preparation approaches, particularly if considering they constitute the most time-consuming step of the analytical method and the main source of laboratory wastes. Among the alternatives explored, it is important to highlight the miniaturization of the extraction methods, which has been accompanied by the seek of greener solvents and sorbents. Biopolymers emerge as potential candidates to be used as sorbents in microextraction schemes given their biodegradability, versatility, and easily functionalization. This review offers an overview on biopolymers (chitosan, cellulose, alginate, and agarose) in sorbent-based microextraction approaches, paying attention to the preparation of the sorbent and the format in which biopolymers are incorporated into the sorbent/device, thus implying a specific microextraction approach, their role in the resulting sorbent material, and the reported analytical applications, covering environmental, food, and bioclinical analysis.

“…Polysaccharides have undergone the most widespread explorations in the extraction of endogenous and exogenous compounds from plants. Chitosan and cellulose have been used in different formats, including as dispersants [62][63][64], SPE cartridges [65,66], nanoparticles [67,68], and fibers [69], thanks to their versatility. Unlike cellulose, which is abundant in the walls of vegetal cells, chitosan is mainly derived from the skeletons of marine animals, as a deacylated form of chitin.…”

“…The use of natural sorbent as such should be preferable in order to develop green methods, simplify the process and reduce the number of tedious synthetic steps that are normally required when numerous phases are involved. In many examples, natural materials exhibit excellent extraction capacities thanks to their specific functional groups and porous structures, which allow proper interactions with the target analytes without further functionalization [62][63][64]66,70,73]. On the other hand, the functionalization and/or combination of different sorption mechanisms can enhance extraction performance, and a number of works have developed hybrid phases starting from natural sorbents.…”

“…One of the main advantages of MSPD is its ability to directly extract solid materials, which is particularly important for plant samples that normally require pre-treatment before extraction. As shown in figure 2e, cellulose and chitosan can act as optimal dispersants and sorbents in MSPD, and have been successfully employed for the extraction of phenols [63] triterpenoid acids [62], anthraquinones [72] and caffeoylquinic acid derivatives [64] from various vegetal samples. Er et al [75] and Xu et al [67] have coupled natural sorbents with a miniaturized version of magnetic dispersive SPE (m-µ-dSPE) to develop a truly sustainable procedure.…”

Analyses in the plant field have to cover a wide range of topics, starting from metabolomics to the quali-quantitative determination of a single or a class of metabolites, often dealing with very complex matrices. The development of an appropriate sample preparation method is fundamental to obtain complete information, because downstream analyses will detect only the metabolites previously extracted. The choice of the proper extraction phase is therefore of utmost importance and the most critical parameter to be considered. Although most of the studies on plants still mainly adopt traditional extraction techniques, a wide number of new phases with improved features in terms of tunability, selectivity and, most important, sustainability have been developed in the past decades and applied to the study of natural products. This review provides an overview of the new extraction phases developed and adopted for the study of plant endogenous and exogenous metabolites.

“…Matrix solid‐phase dispersion (MSPD) is a relative sample preparation method in which sample homogenization, disruption, extraction, fractionation, and purification were simultaneously performed in one step and shorter extraction time was required [26]. Recently, many MSPD methods have been successfully used in the extraction of medicine and food [27–32]. At present, a vortex‐homogenized MSPD technique not only retained the superiority of the traditional MSPD method, but also overcame the shortage of the loss of analytes in complex procedures.…”

A novel and simple method was established for the extraction and determination of seven compounds in Anemarrhena asphodeloides Bge. using silica gel-based vortex-homogenized matrix solid-phase dispersion and ultra-high performance liquid chromatography quadrupole-time of-flight mass spectrometer. The conditions for the extraction were optimized. Silica gel was used as the dispersant, 50% methanol-water was selected as an elution solvent and the grinding time was 3 min. Compared with the traditional ultrasonic-assisted extraction, the developed method was rapid and efficient. In order to screen potential antioxidants, extract dealing with the optimized method was applied to a polyamide chromatography column and a D-101 macroporous resin column. Fr.2.2 showed the highest antioxidant activities with the most content of flavonoid. A total of 25 peaks were identified from the active fraction. A 2,2 ′ -diphenyl-1-picrylhydrazyl ultra-high performance liquid chromatography coupled with mass spectrometry approach was adopted for the rapid and exact screening and identification of antioxidant compounds. It indicated that flavonoids exhibited potential antioxidant activities. The antioxidant activities of nine monomeric compounds in vivo were tested. Structure-activity relationships were discussed.Five flavonoids with the concentration of 500 µg/mL would reduce the oxidative stress of PC12 cells that were induced with 2,2 ′ -azobis[2-methylpropionamidine] dihydrochloride.
