J. Planar Chromatogr. 20, 203-207 (2007).. HPTLC of epalrestat (5-[(1Z,2E)-2-methyl-3-phenylpropenylidene]-4-oxo-2-thioxo-3-thiazolidineacetic acid) with nitrofurantoin as internal standard on silica gel with ethyl acetate - toluene - acetic acid 30:20:1. Densitometric scanning in absorbance mode at 290 nm.
J. Planar Chromatogr. 21, 49-54 (2008). Report of a new procedure for separation of complex mixtures by combining different modes of multidimensional planar chromatography on silica gel plates. Initially the complex mixture was separated into five groups of compounds. Mobile phases for separation of these different groups were then optimized by regarding each group as individual separation problem. By use of this new procedure 22 compounds from a complex mixture were separated on 10 x 10 cm TLC and HPTLC plates. TLC and HPTLC of 22 pesticides on silica gel with ethyl acetate - n-heptane 2:3 for TLC and 1:1 for HPTLC in the first direction. After removal of some of the adsorbent layer five further development steps with different eluents followed resulting in the complete separation of the 22 compounds of interest . Detection under UV 254 and 366 nm.
strain S24. Arzneim.-Forsch./Drug Res. 56, 171-179 (2007). TLC of SJA-95 and mycosamine on silica gel with butanol - acetic acid - water - tetrahydrofuran 6:2:2:1 and butanol - acetic acid - water - dioxane 6:2:2:1. Detection under UV 254 nm and under white light after spraying with ninhydrin reagent.
Pharmazie 62, 900-901 (2007). TLC of dihydroartemisinin and the degradation products 2-(3-oxobutyl)-3-methyl-6-(2-propanol)-cyclohexanon and 2-(3-oxobutyl)-3-methyl-6-ethyl-cyclohexanon on silica gel with chloroform - methanol 19:1. Detection by spraying with vanillin reagent (0.5 g vanillin in 80 mL sulfuric acid and 20 mL ethanol).
J. Planar Chromatogr. 21, 103-106 (2008). HPTLC of (-)-epicatechin, (+)-catechin, (-)-epigallocatechin, (-)-gallocatechin, (-)-catechin gallate, and (-)-epicatechin gallate on RP-18 at room temperature and 75 % relative humidity in an automated development chamber with methanol - water - formic acid 30:70:6. Detection by spraying with diazotized sulfanilic acid. Quantitation by densitometry at 440 nm.
Chromatographia 69(3-4), 351-356 (2009). TLC of piroxicam and its degradation products on silica gel with ethyl acetate – toluene - butylamine 2:2:1. Quantification by absorbance measurement at 360 nm. It was found that piroxicam decomposes to produce pyridine-2-amine and 2-methyl-2,3-dihydro-4H-1?6,2-benzotiazin-1,1,4-trione, based on 1H NMR and LC–MS–MS qualification data.
J. Liq. Chromatogr. Relat. Technol. 31, 752-762 (2008). TLC and HPTLC of nine dipeptides (gly-gly, ala-gly, pro-leu, pro-asp, pro-gly, leu-pro, ala-pro, phe-pro, val-pro) on silica gel with ethanol - dichloromethane 2:1 and methanol - dichloromethane 1:1 in a horizontal chamber saturated for 20 min. Detection by spraying with sodium azide and starch solution (25 mL aqueous starch solution, containing 2.5 g starch, was added to 20 mL aqueous sodium azide solution containing 2 g sodium azide, the mixture was adjusted to pH 5.5 with 0.1 mol/L hydrochloric acid and diluted to 50 mL with water to obtain 4 % and 5 % solution for sodium azide and starch, respectively). All solutions were prepared fresh daily. The limit of detection was 2-200 pmol/spot for the iodine azide procedure, 1-100 pmol/spot for iodine, 20-2000 pmol/spot for UV 254 nm, and 40-1000 pmol/spot for spraying with ninhydrine and drying at 110 °C .
Chromatographia 69 (1-2), 157-161 (2009). TLC of amlodipine besylate (AML) and valsartan (VAL) on silica gel with toluene - methanol - acetic acid 70:30:1. Quantification by absorbance measurement at 244 nm. Linearity was between 100 - 600 ng/spot for AML and 1600 - 9600 ng/spot for VAL. For AML the RSD of intra-day precision was 1.5 - 1.8 % and of inter-day precision 1.2 - 2.0 %. For VAL the RSD of intra-day precision was 0.1 - 0.4 % and of inter-day precision 0.2 - 0.5 %. Accuracy was 98.3 % for AML and 98.7 % for VAL.
