On-line high performance liquid chromatography (HPLC) coupled with three biochemical detection (BCD) methods was applied to evaluate bioactive components in Danshen injection. On-line HPLC-photo-diode array-fluorescence detection based on the fluorogenic substrate 7-acetoxy-1-methyl quinolinium iodide, was built to search acetylcholinesterase (AChE) inhibitors in Danshen injection. On-line HPLC coupled with the scavenging assay of 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) free radicals was developed to screen antioxidants. The three active profiles were obviously different. Radical scavenging profiles revealed seven strong peaks in the chromatographic fingerprint possessing obvious free radical inhibition effects, while some minor peaks exhibited stronger AChE inhibition activities. The main radical scavengers and AChE inhibitors were identified by HPLC-MS. Several unknown ingredients showing strong AChE inhibition activities needed further identification except protocatechuic aldehydrate, salvianolic acid H or I and lithospermic acid. The on-line multiple on-line HPLC-BCD methods will provide powerful tools in the field of pharmacognosy for fast-track identification of interesting and/or novel bioactive compounds.

Acanthopanax sessiliflorus, belonging to the Araliaceae family, is used as medicinal herbs and dietary supplements, and can be consumed as seasoned vegetables, salads, pickles, functional tea, and wine. Their edible parts (shoots, leaves, fruis, and stems) are considered as a highly valuable food source with health benefits. The comparison of the qualitative and quantitative characteristics of functional compounds in these plant parts is still limited.

Introduction: leaves (FSL), a traditional Chinese ethnomedicinal herbal material used to prepare health-promoting infusions and pharmacologically noted for their robust anti-inflammatory, antioxidant, and broad-spectrum antiviral activities, nevertheless have an as-yet-uncharacterized molecular mechanism of action against human adenovirus (HAdV).
Methods: Ultra-high-performance liquid chromatography coupled with Q-Exactive Orbitrap mass spectrometry (UHPLC-Q-Exactive-Orbitrap/MS) was employed to identification of FSL components. Publicly available GEO datasets were mined to identify HAdV-associated differentially expressed genes (DEGs).

Non-steroidal anti-inflammatory drugs (NSAIDs) residues pose a potential threat to aquatic ecosystems and food safety. In this work, novel imine bond/pyridine nitrogen-rich magnetic microporous organic networks (MMONs-Br and MMONs-I) were synthesized via a facile one-pot strategy using brominated and iodinated precursors for the detection of NSAIDs in fish. Brunauer-Emmett-Teller analysis revealed a striking 11-fold difference in specific surface areas between the two materials (MMONs-Br: 293.

Food contamination by per- and polyfluoroalkyl substances (PFAS), especially ultra-short-chain (USC) compounds, poses a growing concern due to their environmental persistence and potential health risks. Despite the developing regulatory framework, analytical challenges persist in quantifying polar USC-PFAS in complex content food matrices. This study presents the development and validation of a novel high-performance liquid chromatography coupled to a tandem mass spectrometer (HPLC-MS/MS) method for the accurate determination of USC-PFAS (carbon chain length from one to four, C1-C4) in tomato-based products (i.

The quantification of sucrose and other carbohydrates in sugar beet roots is essential prior to their processing to assess sugar production yield. In this study, a rapid, highly sensitive and selective ultra-fast liquid chromatography coupled with time of flight mass spectrometry (UFLC-ToFMS) method was developed and validated for the simultaneous analysis of monosaccharides (fructose, glucose-galactose), a disaccharide (sucrose), and a trisaccharide (raffinose). The method showed 1000-fold higher sensitivity, with LOD and LOQ ranging between 0.
