Quantitative HPTLC of silybin - a comparison to quantitative HPLC. GIT Suppl. Chromatographie 3, 4-11 (1987). With the aid of an optimized HPTLC procedure silybin was quantitatively determined after extraction with methanol in the drug cardui mariae, besides Silydianin, Silydristin and Taxifolin. The extraction procedure was simplified and optimized with a view to systematic errors. The statistical comparison of the results with those established by HPLC, shows the equivalence of both analytical methods. Under the aspect of the expenditures (time, personnel, appliances) as well as total operating costs HPTLC turnes to be a most appropriate method for this routine analysis.
Biomed. Chromatogr. 9, 113-122 (1995). HPTLC of porphyrin methyl esters on silica with ethyl acetate - dichloromethane - carbon tetrachloride 1:1:1. Detection under UV, by fluoro densitometry, or MS. Also HPLC method. Discussion of the porphyrin metabolites in human porphyria cutanea tarda and in rats treated with hexychlorobenzene.
Sz. Nyiredy, A. Kakuk (eds.): Planar Chromatography 2000, Lillafüred, Hungary, 24-26 June 2000, Res. Inst. for Med. Plants, p. 109-119. A new off-line OPLC operation called infusion OPLC dramatically reduces the disturbing effect of front of total wetness. Moreover, pre-wetting the layer with a small amount of weak non eluting eluent prior to separation eliminates it totally. Both variations yield more efficient separation compared with conventional transfusion off-line OPLC.
R.E. KAISER (Ed). Proc. of the 3rd Int. Symp. on Instr. HPTLC, Würzburg, IfC, Bad Duerkheim (1985), 277-280. Optimization of the instrumentation of quantitative HPTLC for the analysis of antibiotics by off-line use of an autosampler, a TLC scanner and a computer.
Basic algorithms of image processing. Sz. Nyiredy, A. Kakuk (eds.): Planar Chromatography 2000, Lillafüred, Hungary, 24-26 June 2000, Res. Inst. for Med. Plants, p. 107. Sz. Nyiredy, A. Kakuk (eds.): Planar Chromatography 2000, Lillafüred, Hungary, 24-26 June 2000, Res. Inst. for Med. Plants, p. 107. Basic principles of image processing in HPTLC (pixels, color-systems and imaging operations), definitions of scanning densitometry and two-dimensional digitized chromatograms are demonstrated.
J. Planar Chromatogr. 30, 164-169 (2017). HPTLC of hexyl nicotinate on silica gel with acetone ‒ n-hexane 3:7. Chemical stability analysis was performed in aqua–ethanolic solutions stored in ordinary and quartz flasks heated at 40 °C and exposed to UV radiation at 254 nm. The main products of chemical changes of hexyl nicotinate are the substances with hRf 37 and 68. Preliminary identification of the decomposition products was achieved by GC–MS analysis.
Chinese J. Pharm. Anal. 8, 183-185 (1988) (Yaowu Fenxi Zazhi). TLC on silica with methyl chloride - acetone 3:1 and 1.5:1 or twice development with cyclohexane - acetone 15:15, or on silica, impregnated with 5% paraffin, with methanol - water 55:45. Detection by spraying with 20% H2SO4 in ethanol for the former, and by spraying with 5% hydrochloric acid in ethanol and heating at 120°C for 5 min. for the latter.
J. Planar Chromatogr. 3, 413-416 (1990). Thermodynamic description of adsorbent - binary solution - solute system in order to characterize a given chromatographic process and investigation of the effect of the chromatographic technique employed, i.e. thin layer or column liquid, on the thermodynamic description of the chromatographic system.
