“…A few neotype of materials were also applied as adsorbent or dispersant during the MSPD. Molecular-sieve-based MSPD has been proposed and developed for extracting the active compounds [19][20][21][22]. Molecular sieve has a 3D interconnecting network formed by silica and alumina tetrahedra as crystalline metal aluminosilicates.…”

A few advancing technologies for natural product analysis have been widely proposed, which focus on decreasing energy consumption and developing an environmentally sustainable manner. These green sample pretreatment and analysis methods following the green Analytical Chemistry (GAC) criteria have the advantage of improving the strategy of chemical analyses, promoting sustainable development to analytical laboratories, and reducing the negative effects of analysis experiments on the environment. A few minimized extraction methodologies have been proposed for replacing the traditional methods in the quality evaluation of natural products, mainly including solid‐phase microextraction (SPME) and liquid phase microextraction (LPME). These procedures not only have no need for large numbers of samples and toxic reagent, but also spend a small amount of extraction and analytical time. This overview aims to list out the main green strategies on the application of quality evaluation and control for natural products in the past 3 years.

“…In the past decades, a large number of online enrichment CE methods has been developed including field-amplified sample stacking, micelle to cyclodextrin stacking (MCDS), micelle to solvent stacking (MSS), electronic supercharging, and sweeping [15][16][17]. For the demand of higher sensitivity, the combination of multiple online preconcentration as two-step or three-step methodology such as sweeping-MSS, FASI-Sweeping-MSS, and field-enhanced sample injection (FESI)-MCDS has become a new trend [18][19][20]. Among them, FESI-MCDS is a new two-step online stacking strategy featured by simplicity, environmental friendly, and high sensitivity, which is promising for the analysis of neutral analytes in complex sample matrix.…”

A rapid, sensitive, environmental friendly dual preconcentration method by combining micro matrix solid-phase dispersion extraction with field-enhanced sample injection and micelle to cyclodextrin stacking has been developed for the determination of furocoumarins. Molecular sieve, KIT-6, was used as an adsorbent in micro matrix solid-phase dispersion process. The important parameters affecting off-line and online CE preconcentration efficiency were optimized. Under the optimal experimental conditions, all analytes showed good linearity (R 2 > 0.999). The LODs of notopterol, isoimperatorin, and imperatorin were 0.1 μg/mL, 1.2 mg/kg, and 1.0 mg/kg, respectively. Compared with the normal CE method, the enrichment times were up to 300. Moreover, Angelicae Dahuricae Radix was used as the mode of complex solid sample matrix to demonstrate the prospect of application of this methodology. The results showed the proposed strategy is promising for determining trace furocoumarins in complex matrix samples, which might be applied as a powerful and economic tool in monitoring illegal cosmetic adding.

“…Among these methods, on‐line sample stacking is the most popular one since it has merits of easy control, accumulating and separating analytes simultaneously, and no need to modify the instrumentation. Many on‐line stacking techniques, e.g., field‐amplified sample stacking (FASS) , micelle to solvent stacking , transient isotachophoresis , large volume sample stacking , and micelle to cyclodextrin stacking (MCDS) have been proposed and developed since the 1980s.…”

A novel on‐line synergistic proconcentration strategy coupling field‐amplified sample stacking and micelle to cyclodextrin stacking for cationic analytes in capillary zone electrophoresis has been proposed and applied for the separation and determination of two alkaloids, matrine, and oxymatrine in complicated matrix samples. The approach was performed by the long injection of sample in a low‐conductivity sodium dodecyl benzene sulfonate solution followed by the injection of hydroxypropyl‐β‐cyclodextrin solution in higher conductivity. The stacking mechanism of this method has been expounded and parameters affecting stacking effect have been optimized in our study. Under the optimum experimental conditions, 169‐ and 218‐fold sensitivity improvements were achieved for matrine and oxymatrine when compared with normal injection. Analytical indicators including linearity, limits of detection, and reproducibility (intra‐ and inter‐day relative standard deviations) were evaluated. Moreover, sample matrix effect was studied using compound flavescent sophora and salicylic acid powder and spiked urine samples. The developed method is an attempt for the combination of micelle to cyclodextrin stacking with other stacking methods. It could be a good alternative choice for the determination of alkaloids in a complex sample matrix.
