- by MS ArticlesABSTRACT Cembranoids are significant flavor precursors found in flue-cured tobacco leaves. The degradation products can serve as important aromatic compounds. In this study, 16 cembranoids were discovered in flue-cured tobacco leaves by liquid chromatography–mass spectrometry (MS), and 1 cembranoid featuring both oxidation and dehydrogenation from α/β-cembranoid was identified for the first time. α- and β-cembranoids were confirmed to be precursors […]

- by MS ArticlesABSTRACT Mume Fructus (MF), a representative substance in the field of medicine-food homology, has been extensively utilized in clinical treatments and daily diets for its raw and processed forms. This study aimed to establish the spectrum-effect relationship between ultra–high-performance liquid chromatography coupled with quadrupole tandem time-of-flight mass spectrometry (UHPLC-Q-TOF-MS/MS) fingerprints and anti-inflammatory and antitussive activities of raw and processed MF […]

- by MS ArticlesAbstract The spatial metabolic analysis of tumor tissues following neoadjuvant chemotherapy (NAC) is critical for understanding chemotherapy-induced metabolic changes. Matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI MSI) offers a powerful tool for revealing spatially resolved metabolic profiles within tissues. However, necrotic regions in post-NAC tissues are fragile, creating challenges for sample preparation and MALDI MSI analysis. In this study, we […]

- by MS ArticlesABSTRACT Metabolomics, a powerful discipline within systems biology, aims at comprehensive profiling of small molecules in biological samples. The challenges of biological sample complexity are addressed through innovative sample preparation methods, including solid-phase extraction and microextraction techniques, enhancing the detection and quantification of low-abundance metabolites. Advances in chromatographic separation, particularly liquid chromatography (LC) and gas chromatography (GC), coupled with high-resolution […]
- by MS ArticlesABSTRACT The widespread use of organophosphorus pesticides (OPs) has raised significant environmental and health concerns due to their residues in soil and potential entry into the food chain. This study introduced chiral analysis methods for four OPs—methamidophos (METHP), dipterex (DIP), malathion (MALA), and isothiophos-methyl (ISOME)—using liquid chromatography–tandem mass spectrometry (LC–MS/MS) with cellulose-based chiral columns. Three distinct methods were established: one […]
