ABSTRACTα‐Glucosidase plays important roles in the digestion and absorption of carbohydrates in the small intestine. The inhibition of α‐glucosidase is regarded as a potential way to treat diabetes. We established an approach to screening α‐glucosidase inhibitors from medicinal plants ...... hiện toàn bộ
AbstractThis treatise summarizes the underlying principle and the road map for systematic LC‐MS/MS bioanalytical method development. The three themes that have recently emerged as central to building quality during method development—phospholipids, incurred sample and sound chromatographic considerations—are the main focus of this article. In order to reduce the bi...... hiện toàn bộ
AbstractLiquid chromatography/electrospray ionization tandem mass spectrometry (LC/ESI‐MS/MS) is one of the most prominent analytical techniques owing to its inherent selectivity and sensitivity. In LC/ESI‐MS/MS, chemical derivatization is often used to enhance the detection sensitivity. Derivatization improves the chromatographic separation, and enhances the mass ...... hiện toàn bộ

AbstractAcetonitrile, an organic solvent miscible with aqueous phase, has seen thousands of publications in the literature as an efficient deproteinization reagent. The use of acetonitrile for liquid–liquid extraction (LLE), however, has seen very limited application due to its miscibility with aqueous phase. The interest in LLE with acetonitrile has been pursued a...... hiện toàn bộ
AbstractThe chiral resolution of some clinically used drugs namely metoprolol, teratolol, tolamolol, nebivolol (β‐adrenergic blockers), econazole, miconazole (anti‐fungal agents), cromakalim (anti‐hypertensive agent) and etodolac (anti‐inflammatory agent) was achieved on cellulose tris (3,5‐dichlorophenylcarbamate) chiral stationary phase. The mobile phase used was...... hiện toàn bộ

AbstractFabric phase sorptive extraction (FPSE), a recently introduced novel sample preparation technology, has been evaluated for the extraction of benzodiazepines from human blood serum. FPSE utilizes a flexible fabric surface as the substrate platform for creating sol‐gel hybrid organic‐inorganic sorbent coatings. FPSE media can be introduced directly into the s...... hiện toàn bộ
