In this paper, the potential applications of metal–organic framework (MOF) materials as fiber coatings for solid-phase microextraction (SPME) polycyclic aromatic hydrocarbons (PAHs) in water samples were explored. Fibers coated with MIL-53(Al, Cr, Fe) fabricated by an adhesive method SPME. The quantitation was performed gas chromatography–tandem mass spectrometry (GC–MS/MS) using multiple reaction monitoring mode. Among three MIL-53(M) coatings, MIL-53(Al) showed highest extraction...
This study developed a new zirconium metal–organic framework (MOF) luminophore named Zr-DPA@TCPP with dual-emission electrochemiluminescence (ECL) characteristics at resolved potential. First, core–shell structure was effectively synthesized through the self-assembly of 9,10-di(p-carboxyphenyl)anthracene (DPA) and 5,10,15,20-tetra(4-carboxyphenyl)porphyrin (TCPP) as respective organic ligands Zr cluster metal node. The reasonable integration two DPA TCPP ECL properties into single monomer,...
Tripleurospermum limosum (TL) has been used in folk medicine to treat gastritis. Toward the further development and use of TL, we report phytochemical profiling, determination active components, antioxidant enzyme inhibitory activities TL. Nineteen compounds were identified by ultra-performance liquid chromatography-electrospray ionization-orbitrap-mass spectrometry for first time this plant. Phytochemical studies indicated that TL contained 11 types phytochemicals. The components [total...
The conventional use of Heracleum moellendorffii Hance is for wind dispelling and toxin removal. This research aims to enhance the understanding flowering aerial parts this plant by analyzing its volatile oil. Hydrodistillation was employed extract essential oil, which subsequently analyzed using gas chromatography coupled with mass spectrometry. analysis revealed presence 50 compounds, accounted 92.67% oil's composition. major constituents include germacrene D (21.78%), n-octyl acetate...
Owing to the limitations of dual-signal luminescent materials and coreactants, constructing a ratiometric electrochemiluminescence (ECL) biosensor based on single luminophore is huge challenge. This work developed an excellent zirconium metal–organic framework (MOF) Zr-TBAPY as ECL luminophore, which simultaneously exhibited cathodic anodic without any additional coreactants. First, was successfully prepared by solvothermal method with 1,3,6,8-tetra(4-carboxyphenyl)pyrene (TBAPY) organic...
Anemone baicalensis, a plant abundant in Northeast China, has garnered attention for its potential medicinal properties. While aerial parts (ABAP) have demonstrated significant antioxidant activity, the rhizome (ABR) remains less explored, particularly comparison to well-documented Anemones raddeanae Rhizoma, valuable traditional Chinese medicine. This study investigates chemical composition and bioactivity of ABR, comparing it with ABAP evaluating as substitute Rhizoma. Phytochemical...
This research explores the structural composition and antioxidant abilities of pectins extracted from Adenophora tetraphylla (Thunb.) Fisch. Pectins, which are a complex group acidic polysaccharides, exhibit various biological activities due to their unique domains. Following aqueous extraction, underwent sequential purification using ion exchange gel permeation chromatography techniques. FT-IR NMR techniques were used elucidate characteristics. The investigation was enhanced through...
Polystyrene nanoparticles are emerging as contaminants in freshwater environments, posing potential risks to amphibians exposed extended periods of water contamination. Using tadpoles a model, this study aimed evaluate the toxicity PS NPs. Pyrolysis-gas chromatography-tandem mass spectrometry (Py-GCMS) analysis revealed concentration-dependent increase polystyrene (PS NPs) levels with escalating exposure concentrations. Following 100 nm fluorescent microspheres, fluorescence was observed...
A novel modified micro-solid-phase extraction (μ-SPE) device was developed in this study using hollow fiber-protected metal–organic framework (MOF) materials as sorbents. Polychlorinated biphenyls (PCBs) were used model compounds. Gas chromatography with tandem mass spectrometry (GC-MS/MS) for sample quantification and detection. Important factors that affect the investigated optimized detail. The μ-SPE-GC-MS/MS method had low limits of detection (0.15 ng L−1 to 0.63 L−1, S/N = 3),...
Abstract An intermolecular radical cascade reaction between readily prepared o ‐methylthio‐arylamines or ‐methylselanyl‐arylamines and alkynes for the preparation of valuable benzothiophenes benzoselenophenes is reported.
