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 ...
Direct separation of the enantiomers of (+/-)-metoprolol tartrate on impregnated TLC plates with D-(-)-tartaric acid as a chiral selector
(Research Inst Medicinal Plants, Budakalasz, 2005)
A method for chromatographic separation of the enantiomers of (+/-)-metoprolol tartrate (+/- MeT) employing a chiral mobile phase additive (CMPA) is described. By using silica gel plates previously impregnated with the ...
Study of the lipophilicity and retention behavior of some beta-adrenoceptor antagonists
(Springer Nature, 2003)
The chromatographic behavior of some beta-adrenoceptor antagonists has been studied by RP HPTLC on C-18 with water-acetonitrile (phi = 0.2-0.7) and water-dioxane (phi = 0.1-0.5) mobile phases. The retention mechanism was ...
Examination of the hydrophobicity of ACE inhibitors and their active metabolites by salting-out thin-layer chromatography
(Research Inst Medicinal Plants, Budakalasz, 2005)
The behavior of five ACE inhibitors and their active degradation products in salting-out thin-layer chromatography (SO TLC) has been examined on silica gel, cellulose, and polyacrylonitrile (PAN) with aqueous ammonium ...
Salting-out thin-layer chromatography of several myorelaxants
(Research Inst Medicinal Plants, Budakalasz, 2003)
The chromatographic behavior of five myorelaxant drugs has been studied under the conditions used for salting-out thin-layer chromatography (SOTLC) on cellulose and alumina. For this purpose, aqueous ammonium sulfate ...
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 ...
Quantitative analysis of cyproterone acetate and ethinylestradiol in tablets by use of planar chromatography
(Research Inst Medicinal Plants, Budakalasz, 2003)
This paper describes a simple, rapid, and reliable HPTLC procedure for the determination of cyproterone acetate and ethinylestradiol in tablets. Identification and determination were performed on 10 cm x 20 cm, LiChrospher ...
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 ...
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 ...
