Development and application of salting-out assisted liquid/liquid extraction for multi-mycotoxin biomarkers analysis in pig urine with high performance liquid chromatography/tandem mass spectrometry.
Direct determination of urinary mycotoxins is a better approach to assess individual's exposure than the indirect estimation from average dietary intakes. In this study, a new analytical method was developed and validated for simultaneous analysis of aflatoxin B1, deoxynivalenol, fumonisin B1, ochratoxin A, zearalenone and T2 toxin and their metabolites in pig urine. In total 12 analytes were s...
متن کاملDetermination of Organic Sulfur Contaminants Using Hollow Fibre-protected Liquid-phase Micro-extraction Coupled with Gas Chromatography
A simple and solvent-minimized sample preparation technique based on hollow fibre-protected liquid-phase micro-extraction has been developed for extraction of fifteen organic sulphur compounds from aqueous samples. The analysis of the extracted them was performed by gas chromatography equipped with mass spectrometry and/or flame photometric detectors. 3.3 µL of organic solvent located in the lu...
متن کاملPreparative HPLC for large scale isolation, and salting-out assisted liquid–liquid extraction based method for HPLC–DAD determination of khat (Catha edulis Forsk) alkaloids
BACKGROUND Khat (Catha edulis Forsk) is an evergreen shrub of the Celastraceae family. It is widely cultivated in Yemen and East Africa, where its fresh leaves are habitually chewed for their momentary pleasures and stimulation as amphetamine-like effects. The main psychostimulant constituents of khat are the phenylpropylamino alkaloids: cathinone, cathine and norephedrine. RESULTS In this st...
متن کاملApplication and Optimization of Dispersive Liquid-liquid Microextraction Coupled with High-performance Liquid Chromatography for Sensitive Determination of Furfural and Hydroxymethyl Furfural in Jarred and Canned Baby-foods
Background and Objectives: Furfural (F) and hydroxymethyl furfural (HMF) are cyclic aldehydes, which are formed during the heat processing of foods. These chemical contaminants have received much attention due to their suspected health hazards and heat damage indicators. The aim of the present study was extraction and determination of F and HMF in baby-foods using dispersive liquid-liquid micro...
متن کاملSalting out and vortex-assisted dispersive liquid–liquid microextraction based on solidification of floating organic drop microextraction as a new approach for simultaneous determination of phenol and chlorophenols in water samples
In the present research, salting out and vortex assisted dispersive liquid–liquid microextraction based on solidification of floating organic drop microextraction (SO-VADLLME-SFODME) for the extraction and determination of phenol and chlorophenols in water samples followed by HPLC have been studied through a novel, simple, low-cost, selectable and environment friendly (so called green) method....
