Preconcentration and Determination of Mefenamic Acid in Pharmaceutical and Biological Fluid Samples by Polymer-grafted Silica Gel Solid-phase Extraction Following High Performance Liquid Chromatography
Abstract Mefenamic acid is a nonsteroidal anti-inflammatory drug (NSAID) that has analgesic,anti-infammatory and antipyretic actions. It is used to relieve mild to moderate pains. Solid-phase extraction of mefenamic acid by a polymer grafted to silica gel is reported . Poly allyl glycidyl ether/iminodiacetic acid-co-N, N-dimethylacrylamide was synthesized and grafted to silica gel and was used ...

متن کاملdetermination of gamma - aminobutyric acid by high-performance liquid chromatography
gamma-aminobutyric acid is the main inhibitory amino acid neurotransmitter in several areas of the brain. measurement of gamma-aminobutyric acid in the brain will help elucidate its metabolic rote and diagnostic value. the liquid chromatography (lc) system consisted of a delivery pump. male rats (150-250g) were used in this study. the brain was rapidly removed from decapitated animals. trie chr...
متن کاملVortex-Assisted Inverted Dispersive Liquid-Liquid Microextraction of Naproxen from Human Plasma and Its Determination by High-Performance Liquid Chromatography
Extraction and determination of naproxen from human plasma were performed using Vortex-Assisted Inverted Dispersive Liquid-Liquid MicroExtraction (VA−IDLLME) and High-Performance Liquid Chromatography (HPLC). The parameters affecting extraction recovery such as type and volume of extraction and disperser solvents, pH of sample solution, stirring rate, extraction time and salt addition were ...
متن کاملDetermination of chemical and radiochemical purity of [14C] clozapine by high performance liquid chromatography and liquid scintillation [Persian]
Introduction: The mechanism of action and metabolism of clozapine, a complex drug used in psychopharmacology, is not completely understood. The effects of this compound in human body are related to some interactions with serotonin and dopamine neurotransmitter receptors. To further elucidate the mechanism of action and to support ongoing drug metabolism studies, [14C] clozapine with suita...
متن کاملDetermination of trans-resveratrol in grapes by pressurised liquid extraction and fast high-performance liquid chromatography.
A study has been made of the extraction of trans-resveratrol from grapes using pressurised liquids (PLE); for this, the first stage was to determine the stability of this compound during extractions at different temperatures (50, 100, 150 degrees C), with quantitative recoveries being obtained up to 150 degrees C. By employing solid-phase extraction (SPE) it was possible to retain this compound...
