Quantitative Structure-Retention Relationship Modeling of the Retention Behavior of Guanidine and Imidazoline Derivatives in Reversed-Phase Thin-Layer Chromatography
(Akademiai Kiado Zrt, Budapest, 2015)
The quantitative structure-retention relationship (QSRR) study has been performed in order to investigate the retention behavior of 16 guanidine and imidazoline derivatives in the reversed-phase thin-layer chromatography ...
Simultaneous HPTLC determination of imidazole antimycotics and parabens in creams
(Springer Nature, 2004)
A simple and reliable HPTLC method has been developed for simultaneous determination of antimycotics (bifonazole and econazole nitrate) and preservatives (methyl- and propylparaben) in medicinal creams. Chromatography was ...
Hydrophilic retention mechanism of imidazoline and serotonin receptor ligands in thin-layer and high-performance liquid chromatography systems
(Springer, 2022)
We investigated and compared hydrophilic retention mechanism (HILIC) of ten compounds (imidazoline and serotonin receptor ligands) in the thin-layer chromatographic (TLC) system and the high-performance liquid chromatographic ...
TLC Retention Behavior of Brodifacoum, Bromadiolone, and Coumatetralyl and their Impurities on Different Adsorbents
(Akademiai Kiado Zrt, Budapest, 2009)
The chromatographic behavior of three biocidal technical materials, rodenticide active ingredients brodifacoum, bromadiolone, and coumatetralyl, and impurities present in the technical material was investigated by both ...
Optimization of the Thin-Layer Chromatography Method for the Separation of Ziprasidone and Its Impurities
(Akademiai Kiado Rt, Budapest, 2016)
The experimental design and the quantitative structure-retention relationship (QSRR) study were applied in order to investigate the retention behavior and to select optimal experimental conditions for the separation of ...
Development of a Reversed-Phased Thin-Layer Chromatography Method for the Lipophilicity Prediction of 17β-Carboxamide Glucocorticoid Derivatives
(Akademiai Kiado Zrt, Budapest, 2018)
Octanol-water partition coefficients (log Po/w) of fifteen previously synthesized 17 beta-carboxamide glucocorticoid derivatives and prednisolone were determined using shake-flask method. The retention behavior of selected ...
Quantitative analysis of nimesulide in plasma by thin-layer chromatography: Application to pharmacokinetic studies in man
(Research Inst Medicinal Plants, Budakalasz, 2003)
A thin-layer chromatographic (TLC) method for quantitative analysis of nimesulide in human plasma has been developed, validated, and applied to a pharmacokinetic study of healthy volunteers. A previously published method ...
Densitometric determination of omeprazole, pantoprazole, and their impurities in pharmaceuticals
(Research Inst Medicinal Plants, Budakalasz, 2004)
A method has been developed for separation of omeprazole and pantoprazole, and their impurities omeprazole sulfone and N-methylpantoprazole, by HPTLC. The mobile phase chloroform-2-propanol-25% ammonia-acetonitrile, 10.8 ...
Comparison of HPTLC and HPLC for determination of econazole nitrate in topical dosage forms
(Research Inst Medicinal Plants, Budakalasz, 2004)
HPTLC and HPLC methods have been established for separation and quantitative determination of econazole nitrate. HPTLC was performed on silica gel plates with n-butyl acetate-carbon tetrachloride-methanol-diethylamine, 3 ...
Analysis of the Retention Behavior of Selected Antipsychotics and Their Impurities by Thin-Layer Chromatography
(Akademiai Kiado Rt, Budapest, 2017)
The retention behavior and lipophilicity of aripiprazole and its nine impurities as well as ziprasidone and its five impurities have been examined by thin-layer chromatography using RP-18 stationary phase and different ...
