J. Planar Chromatogr. 17, 177-180 (2004). HPTLC of bifonazole, econazole nitrate, methyl- and propylparaben on silica gel with ethyl acetate - n-hexane - methanol - ammonia - diethylamine 5:40:8:4:20 in a twin-trough chamber. Quantitation by scanning in reflectance/absorbance mode at 230 nm (econazole nitrate), 250 nm (bifonazole), and 300 nm (parabens).
IPC 56th 2004, Abstract No. GP-11. Stability indicating HPTLC determination of indapamide in tablets on silica gel with toluene - methanol 7:3. Quantitative determination by scanning at 246 nm. Optimization of experimental parameter such as band size, chamber saturation, and slit width. The method was linear in the range of 1.4 - 3.72 g, recovery was 100.01 %. The drug was subjected to stress conditions according to ICH guidelines, degradation products were separated from the pure drug. The method was validated for accuracy, precision, linearity, and specificity.
J. Planar Chromatogr. 17, 305-308 (2004). TLC of manganese(II), chromium(III), nickel(II), cobalt(II), iron(III), and zinc(II) on cellulose with acetonitrile - hydrochloric acid - water 73:15:12 as optimum ternary mobile phase. Detection by spraying with 0.1 g quercetin in 100 mL 2-propanol and 10 g dimethylglyoxime in 100 mL ethanol and exposition to ammonia vapor. Recording of the colored spots under white light by means of a highly sensitive CCD color video camera.
J. Planar Chromatogr. 18, 314-318 (2005). TLC of iridoids (e. g. aucubin, catalpol, harpagide, 8-O-acetylharpagide, ajugoside) from aqueous plant extracts on silica gel with chloroform - methanol - water 25:10:1 and 160:55:8 and ethyl acetate - formic acid 7:4. Detection by spraying with a solution of 1 % 4-dimethylaminebenzaldehyde in conc. HCl containing acetic anhydride (Ehrlich’s reagent) and heating at 105 °C for 5 min. Quantitation by densitometry at 540 nm.
J. Planar Chromatogr. 18, 419-422 (2005). TLC of fenitrothion on silica gel in a horizontal chamber with ethyl acetate - n-heptane 1:4. Quantitative determination by scanning with a diode-array spectrophotometer from 191 to 612 nm.
J. Planar Chromatogr. 18, 234-239 (2005). TLC of Evolvulus alsinoides extracts and the marker EA 1, i.e. 3beta,23,24-trihydroxyolean-12-en-28-oic acid, on silica gel with n-hexane - ethyl acetate 7:3 in a saturated chamber. The marker EA 1 was detected under UV light at 366 nm as a yellow fluorescent band of Rf 0.8. Quantitative determination by absorbance measurement at 232 nm (=UV max of EA 1). Limit of detection 11.6 ng; satisfactory recovery from 93.3 to 96.6 %. The marker was isolated from the aerial parts of Evolvulus alsinoides by preparative TLC.
Abstract GP-18, IPC (2005). HPTLC of nimesulide and chlorzoxazone in tablets on silica gel (prewashed with methanol) with toluene - acetone - ammonia 50:50:4. Paracetamol was used as internal standard. Quantitative determination by absorbance measurement at 265 nm. Nimesulide, chlorzoxazone and paracetamol showed hRf values of 80, 73 and 42, respectively. Linearity was obtained between 0.2-1.0 mg/mL with recovery rates of 99.6-100.3 % for both compounds.The method was validated for accuracy, precision, linearity, LOD, and LOQ.
J. AOAC Int. 87, 1319-1322 (2004). TLC of chlorpheniramine and pheniramine maleate in combination with other drugs in pharmaceutical preparations of tablets, syrups, eye and ear drops etc. on silica gel with cyclohexane - chloroform - methanol - diethylamine 9:8:1:2. Detection under UV light at 254 nm and quantitative determination by scanning at 260 nm. Recoveries of CPM and PM were 100.1 +/- 0.8 % and 100.1 +/- 0.9 %, respectively.
