“…Nowadays, the separation and analysis of compounds with high polarity have been the research focus for several decades, especially in pharmaceutical analysis [43][44][45]. In this work, the retention mechanism and chromatographic performance of the resulting stationary phase for the separation of diverse analytes (including ginsenosides, sulfonamides, and nucleosides) were studied carefully.…”

The molecular imprinting technique has aroused great interest in preparing novel stationary phases, and the resulting materials named molecularly imprinted polymers coated silica packing materials exhibit good performance in separating diverse analytes based on their good characteristics (including high selectivity, simple synthesis, and good chemical stability). To date, monotemplate is commonly used in synthesizing molecularly imprinted polymersbased stationary phases. The resulting materials always own the disadvantages of low column efficiency and restricted analytes, and the price of ginsenosides with high purity was very high. In this study, to overcome the weaknesses of molecularly imprinted polymers-based stationary phases mentioned above, the multi-templates (total saponins of folium ginseng) strategy was used to prepare ginsenosides imprinted polymer-based stationary phase. The resulting ginsenosides imprinted polymer-coated silica stationary phase has a good spherical shape and suitable pore structures. Additionally, the total saponins of folium ginseng were cheaper than other kinds of ginsenosides. Moreover, the ginsenosides imprinted polymer-coated silica stationary phase-packed column performed well in the separation of ginsenosides, nucleosides, and sulfonamides. The ginsenosides imprinted polymer-coated silica stationary phase possesses good reproducibility, repeatability, and stability for seven days. Therefore, a multitemplates strategy for synthesizing the ginsenosides imprinted polymer-coated silica stationary phase is considered in the future.

“…As for LC‐MS, the chromatographic fillers directly affect the separation efficiency of the chromatographic system and the accuracy of data. Porous silica microspheres in inorganic matrix fillers have become the most widely used chromatographic fillers because of their high mechanical strength, good thermal and solvent stability (Liang et al ., 2021). The commonly used mobile phases of gradient elution on HPLC were mixture of 0.1% formic acid in water (Solvent A) and 0.1% formic acid in acetonitrile (Solvent B) (Xiao et al ., 2022).…”

Summary Tea is one of the biggest categories of modern non‐alcoholic beverages with health benefits. Through different processes, tea products are divided into six main types: green tea, yellow tea, white tea, oolong tea, black tea and dark tea. Metabolomics is helpful for the comprehensive, accurate and rapid determination of tea metabolites in different types of tea products and tea processing materials. It has been widely applied in studying the relationship of tea metabolites and its quality. Therefore, it is necessary to summarise the application of metabolomics in tea. In this review, we described and summarised (1) the main metabolites of six types of tea and their implications on tea quality with emphasis on the content differences in the main metabolites in different types of tea; (2) the research on optimising the key processing steps of six types of tea based on metabolomics and the discussion of various new strategies for effectively improving their quality and (3) the advanced approach to characterise and distinguish different grades of tea products via metabolomics. The current review offers guidance for the improvement of tea quality by metabolomics and its potential challenges.

Covalent organic framework (COF) as a kind of crystalline porous material possesses intriguing advantages, including low density, large surface area, permanent porosity, and excellent chemical stability. This novel material has shown great potential in the development of chromatographic stationary-phase materials. In this work, a room-temperature solvothermal method was utilized to yield a uniformly spherical COF-modified silica named Sil-COF. Then, the thiol-ene click chemistry was further used to modify thiolated β-cyclodextrin on the spherical Sil-COF composite for chiral separation called Sil-COF-CD. A series of characterization methods were performed to identify the successful construction of COF-modified stationary-phase materials. Then, three types of nonpolar substances realized baseline separation on the Sil-COF column. In addition, 2-phenylpropionic acid and 1-phenyl-1-propanol were selected as model enantiomers to identify the chiral recognition capability of the Sil-COF-CD column. Sil-COF and commercial β-CD columns were compared to further confirm the superiority of the prepared chiral column. In addition, both COF-modified columns possessed good repeatability. The results open a new avenue to apply spherical chiral COF for the preparation of the HPLC stationary phase.
