“…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.…”

“…Various extraction techniques have been developed for the isolation of compounds from plant samples, and the versatility of these natural materials can grant significant advantages. Several SPE cartridges have been prepared with chitosan [65], pollen [70] cotton [69] and treated food by-products [73], with these being simply packed into a cartridge and the compounds of interest eluted with a suitable organic solvent. Matrix solid-phase dispersion (MSPD) is an extraction method in which a sample is directly ground and mixed with a solid-phase sorbent and the analytes are subsequently isolated, via adsorption onto a SPE cartridge, and eluted with a certain volume of solvent.…”

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.

“…The SPE is a quite common and convenient assistant method to apply sorbent in isolation, which can allow the adsorption of AAI from solvents. Shu et al functionalized a carbon microcoils coated with chitosan as an SPE sorbent to extract AAI from traditional Chinese medicines [10]. In addition, the molecular imprinted polymer technology (MIP) was approved as a practical method to increase the selectivity of the sorbents [11].…”

Aristolochic acid I is a toxic compound found in the genus of Aristolochia plants, which are commonly used as herbal cough treatment medicines. To remove the aristolochic acid I in extract efficiently and selectively, a molecularly imprinted polymer composed of ethylimidazole ionic liquid‐based zeolitic imidazolate framework‐67 was synthesized and used as the adsorbent. Under the conditions optimized by the software design expert, the sorbent showed highest adsorption amount of 34.25 mg/g in methanol/water (95:5, v/v) at 39°C for 138 min. The sorbent was then applied to solid phase extraction to isolate aristolochic acid I from the extract of the herbal plant Fibraurea Recisa Pierre. 0.043 mg/g of aristolochic acid I was obtained after the loading, washing, and elution processes. The limit of detection of 2.41 × 10−5 mg/mL and good recoveries provided evidence for the accuracy of this method.

“…A few typical methods are reported to detect AA‐I and AA‐II in aristolochia and related complex Chinese patent medicines such as thin chromatography , high‐performance liquid chromatography (HPLC) , and capillary electrophoresis (CE) . The HPLC methods for AAs detection are mainly based on different types of detectors such as a diode‐array detector , ultraviolet spectrum (UV) , mass spectrum (MS) , and fluorescence(FLD) detector due to the complex composition in target objects.…”

In this study, a molybdenum disulfide/multiwalled carbon nanotubes (MoS2@MWCNTs) nanocomposite was synthesized by employing a simple hydrothermal method. The flower‐like structure of the MoS2@MWCNTs was characterized via scanning electron microscopy (SEM) and transmission electron microscopy (TEM), and the load of crystalline MoS2 was verified via X‐ray diffraction (XRD) and energy‐dispersive spectroscopy (EDS). The as‐prepared MoS2@MWCNTs nanocomposite was used to modify glassy carbon electrode (GCE) as an electrochemical sensor for detecting aristolochic acids (AAs). With the optimized parameters, the proposed electrochemical sensor exhibited good sensitivity and a broad linear concentration range for detecting AAs from 0.2 to 10 μmol/L and 10 to 100 μmol/L, with the sensitivity of −3.10 μA/(μmol/L) and −0.91 μA/(μmol/L), respectively. The detection limit was also calculated as 0.06 μmol/L (S/N=3) based on the low background signal. Furthermore, the modified electrochemical sensor exhibited good selectivity, repeatability, reproducibility, and stability, thus showing potential application for detecting AA in chinese herbs with good mean recovery and accuracy. In other words, the MoS2@MWCNTs/GCE can be used as an excellent platform to detect AAs.
