Summary: To enrich the flavor and preserve the polyphenolic content in grape juice during long-term storage, different strains of lactobacilli were screened and the optimal fermentation conditions were determined. The retention rate of total polyphenolic compounds remained at 50% after 45 days of storage at 4°C. Various metabolites, including polyphenolics, saccharides, and organic acids, were identified. The grape juice also contained volatile organic compounds (VOCs), mainly esters, aldehydes, and alcohols, which could be formed through complex metabolic pathways involving carboxylic acids and derivatives.

Summary: We conducted a high throughput metabolomic screening using UHPLC-TWINS-QTOF on different parts of R. usambarensis. Through the use of high-resolution mass spectrometry-based metabolomics and chemometric analysis, we were able to distinguish between different aerial parts and identify 153 significant metabolites in leaves, stems, and flowers. The results suggest that flavonoids, benzopyranes, chromones, and xanthones derivatives, along with a richer phytocomplex, may be responsible for the stronger bioactivities obtained from flowers.

Summary: Infrared ion spectroscopy (IRIS) is a useful tool for identifying molecular structures detected in mass spectrometry (MS) experiments. However, coupling LC and IRIS is challenging due to the different timescales. To address this, we propose a heartcutting LC-IRIS approach using two switching valves and two sample loops as an alternative to direct coupling.

Summary: The identification of biotransformation products of drug compounds is crucial for drug development. Liquid chromatography-mass spectrometry (LC-MS) has become the preferred method for metabolite profiling due to its high sensitivity and selectivity. However, determining the full molecular structure of the detected metabolites, including the exact biotransformation site, remains challenging using MS alone.

Summary: Infrared ion spectroscopy is recognized as a method to identify analytes detected by mass spectrometry in various chemical areas, with integration into analytical laboratories being considered. To overcome collisional deactivation at high pressures, high instantaneous power infrared lasers are needed, with most studies currently being performed at infrared free electron laser facilities. The proliferation of this technique in routine analytical laboratories requires table-top infrared lasers, such as optical parametric oscillators (OPOs), which offer high intensities and good spectral tuning ranges.

Summary: In this study, an ionic covalent organic framework (iCOF) surface grafting monolithic sorbent was prepared for in-tube solid-phase microextraction (SPME) of aristolochic acids (AAs) in various samples. The density of quaternary ammonium ions in the iCOF was modulated for enhanced adsorption of AAs. The iCOF surface grafting monolithic sorbent was confirmed by different means. Several operating conditions were optimized to develop the online in-tube SPME-HPLC method, which showed good linearity, low limits of detection, and high recoveries for AAs in serum samples. This study presents a feasible approach for the application of COF-based monolithic sorbents in sample preparation.

Summary: A chitosan-alginate sponge with multiple cross-linking networks was developed for adsorption and enrichment of anionic dyes from food samples. The sponge showed better three-dimensional network structure, mechanical behavior, and stability compared to pure chitosan and alginate sponges. The adsorption performance and selectivity of the sponge were systematically studied, and it maintained high adsorption capacity and selectivity for anionic dyes. The sponge also showed satisfactory reusability and was successfully combined with high-performance liquid chromatography for the enrichment and detection of anionic dyes in candy and cocktail samples.
