Abstract Advanced glycation end products (AGEs) and protein cross-links have been extensively investigated in both food and biomedical fields over the past years. Although there are a few chromatographic and immunological methods for the analysis of selected AGEs, there is no method available for comprehensive simultaneous analysis of major AGEs found in processed foods and biological samples. In the present study, we have reported a validated UHPLC-MS/MS method for simultaneous identification a...

Abstract High-performance liquid chromatographic (HPLC) and subcritical fluid chromatographic (SFC) separations of the enantiomers of structurally diverse, basic s-carboline, tetrahydroisoquinoline and benzazepine analogues of pharmacological interest were performed applying chiral stationary phases (CSPs) based on (i) neutral polysaccharides- and (ii) zwitterionic sulfonic acid derivatives of Cinchona alkaloids. The aim of this work was to reveal the influence of structural peculiarities on the...

Abstract A novel magnetic metal organic framework composite (Fe3O4@MOF-808) was synthesized by a facile solvothermal method and applied as an adsorbent for the magnetic solid phase extraction (MSPE) of benzoylurea insecticides (BUs) from tea beverages and juice samples. The prepared materials were characterized using scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR), X-ray diffractometry (XRD), vibrating sample magnetometry measurements and N2 adsorption-desorpt...

Abstract A simple, effective, convenient and environmentally friendly methodology using high throughput bar adsorptive microextraction (HT-BAμE) with microliquid desorption in combination with large volume injection-gas chromatography-mass spectrometry operating in the selected-ion monitoring acquisition mode (LVI-GC-MS(SIM)) was applied for the determination of nicotine and cotinine in urine samples. Under optimized experimental conditions, the developed methodology allowed for linear dynamic r...

Abstract The performance of the Centrifugal Partition Chromatography (CPC) as a liquid-liquid chromatographic technique depends strongly on the two-phase solvent system used. Thereby the individual influence of the retention of the stationary phase, the coalescence, and the dispersion of the mobile phase in the chambers must be understood to select appropriate solvent systems and reach high separation efficiencies. In this study, an optical measurement system was used to investigate the influenc...

Abstract In this study, a novel magnetic molecularly imprinted polymer (MMIP) was prepared by surface imprinting technology using 2-oxin and 6-HNA as dual virtual templates and 4-vinyl pyridine (4-VP) as the functional monomer for extraction of patulin (PAT) from the surface of magnetic nanoparticles. MMIPs were characterized by fourier transformed infrared (FT-IR) spectroscopy, X-ray diffraction, and vibrating sample magnetometry. The results showed that the molecularly imprinted polymer (MIP) ...

Abstract Recently, in separation science, ionic liquids (ILs) have been commonly used as modifiers for buffer solutions, dynamic coating solutions, or coating solutions on carriers in capillary electrophoresis. However, only several papers have reported the use of chiral ILs as the sole chiral selector. In this paper, a chiral ionic liquid, cholinium-clindamycin phosphate (Ch-CP), was synthesized and employed as a sole chiral selector in capillary electrophoresis (CE). A series of parameters aff...

Abstract In general, the simultaneous separation and isolation of compounds with a broad polarity range from natural products is a challenge by ordinary high-speed counter-current chromatography (HSCCC). Indeed, the complex solvent system screening methods limit the broader application of HSCCC. We describe herein a rapid and efficient linear gradient CCC (LGCCC) method that enables the separation of flavonoid glycosides with a broad range of KD values from custard apple leaves. Inner-recycling ...

Abstract A novel approach for stir membrane liquid phase microextraction of tetracyclines from biological fluids was developed. The microextraction procedure assumed in situ formation of microdroplets of a hydrophobic medium-chain fatty acid (extraction solvent) from homogeneous sample solution containing water-soluble medium-chain fatty acid salt by acidification and simultaneous analytes extraction and organic phase separation into pores of stir membrane disk. Obtained large surface area betwe...

Abstract The preparation of a highly efficient chiral liquid chromatography (LC) column is explored by dynamically coating a reversed-phase porous silicon pillar array column with hydroxypropyl-β-cyclodextrin (Hp-β-CD) as the chiral selector. Analyte mixtures composed of non-steroidal anti-inflammatory drugs were tested to reveal the enantioseparation potential of the column. The mechanism of chiral discrimination was investigated. The adsorbed Hp-β-CDs on the column surface experience different...
