Pharmazie 61, 747-750 (2006). TLC of phenazopyridine and 4 major metabolites (i. a. p-methoxyaniline) on silica gel with chloroform - methanol mixtures. Also irradiation of phenazopyridine adsorbed on silica gel. The drug was dissolved in methanol and mixed with aqueous slurry of silica gel. TLC plates were prepared and wet plate photolyzed as such with a mercury lamp. The plate appeared as yellow chromatogram, which turned dark yellow within 15 min. The progress of reaction was monitored by Co-TLC of a withdrawn scratch with the starting drug.
The case of Bifidobacterium adolescentis MB 239. J. Planar Chromatogr. 22, 321-325 (2009). HPTLC of glucose, fructose, galactose, lactose, raffinose, 1-kestose, nystose, and fructosyl-nystose on diol phase by automated multiple development with acetonitrile - acetone - water and acetonitrile - water. Preliminary isocratic developments were performed at 22-25 °C at 65-75 % relative humidity in a twin trough chamber. Detection by vaporization with 37 % hydochloric acid vapor for 30 min followed by dipping in 4-aminobenzoic acid. Quantitative determination by fluorescence measurement at 313 nm.
Abstracts of 1985 Beijing Conference and Exhibition on Instrumental Analysis, 527 (1985). Report of state-of-the-art on instrumental TLC with special emphasis on a new automated multiple development technique employing reproducible elution gradients demonstrated by several application samples. Discussion of the combination of a densitometer with a desktop computer for controlling, data processing and quantitative evaluation.
J. Planar Chromatogr. 4, 345-359 (1991). Description of the evolution of automated multiple development from manual multiple development through programmed multiple development and discussion of the general role of solvent strength gradients and solvent selectivity emphasizing their application to AMD. The large number of experimental parameters encountered in method development is recognized as one of the main current weaknesses of AMD. The method has, however, a number of attractive features which will ensure continuing interest in the technique.
Anal. Chem. 67, 620-630 (1995). HPTLC of 265 pesticides on silica using AMD with an universal gradient based on dichloromethane. Compilation of the data for migration distances, the UV spectra, and the instrumental detection limits. Confirmation of suspect positive ones by a second analysis applying special gradients optimized for the classes. The pesticides were concentrated by solid phase extraction of 1 L drinking water.
GIT Fachz. Lab. Spez. Chrom. 2/96, 126-129 (1996). Combination of conventional TLC, with subsequent color detection and HPTLC, using AMD and densitometry. - HPTLC screening of amines after reductive cleavage of azoic dyes on silica with dichloromethane - acetonitrile 25:3; detection by coupling with (1-naphthyl)-ethylene diammonium dichloride. Confirmation of positive samples by AMD using a 15-step gradient. Quantification by densitometry at 200, 230, and 300 nm. As alternative TLC with diisopropylether - pentane - diethylamine 12:8:1.
CBS 93, 10-12 (2004). HPTLC of progesterone on silica gel prewashed by development in AMD2 first with chloroform - methanol 1:1 and then with the mobile phase, followed by drying at 80 °C for 15 min. Development in AMD2 with toluene - 2-propanol 10:1 without preconditioning over 60 mm. Quantitative determination by absorbance measurement at 252 nm followed by spectra recording from 200 to 360 nm. The linear working range is 25.7-154.5 ng/zone. Repeatability (standard deviation calculated from the amounts of seven simulated progesterone samples determined on the same plate at three concentration levels in the lower, middle and upper range) is 0.26-1.29 %. Recovery is 99.88-100.97 %. Reproducibility was performed with recycled HPTLC plates.
Pharm. Res. 23, 2024-2029 (2006). HPTLC of the chloroform extract of a lipophilic model drug (tempol benzoate) into a long-chain triacylglyceride (olive oil) after 0, 5, 20 and 45 min of digestion with pancreatin on silica gel, by AMD using an 11 step gradient based on hexane and ethyl acetate. Detection by spraying with an aqueous copper sulfate solution (10 % copper sulfate, 8 % phosphoric acid, 5 % methanol), followed by heating at 150 °C. Quantitative determination by absorbance measurement at 675 nm. Lipid recovery was between 104 and 119 %.
