J. Chinese Trad. Patent Med. (Zhongchengyao) 26 (1), 19-23 (2004). TLC on silica gel in a basic developing system containing diethylamine. Detection by iodine vapour. Identification by standard comparison. Quantitative determination by densitometry at 340 nm. Validation of the method by investigation of the procedures, including sample preparation, mobile phase, visualization, scanning wavelength, linearity range (0.28-1.65 µg, r=0.9991), precision (RSD <1.4 % within plate and <2.4 % plate-to-plate), resolution, repeatability, reproducibility, and recovery (87.2 %-99.7 % for different medicine). Comparison of the results with those obtained by HPLC.
CBS 91, 14-15 (2003). HPTLC of hawthorn extract on silica gel with ethyl acetate - methanol - water - formic acid 50:2:3:6, of passion flower extract on silica gel with tetrahydrofuran - toluene - formic acid - water 16:8:2:1, and of chrysine on RP-18 W phase with tetrahydrofuran - methanol - water - formic acid 4:6:14:1. Detection by dipping the warm plate in natural products reagent (0.5 % in ethyl acetate) followed by dipping in PEG 400 solution (5 % in dichloromethane). Visual evaluation at 366 nm.
littorale. J. Planar Chromatogr. 17, 128-131 (2004). HPTLC of the secoiridoid glucoside swertiamarin on silica gel with ethyl acetate - methanol - water 77:15:5 after pre-saturation for 30 min. Quantitative determination at 250 nm. The method was validated for precision, repeatability, and accuracy and found to be precise.
Indian Drugs 41 (3), 160-164 (2004). Combinations of ofloxacin and tinidazole (1:3) are available as tablet dosage forms. Stability indicating HPTLC of ofloxacin and tinidazole on silica gel with dioxan - ethyl acetate - toluene - acetic acid - water 5.5:5:3.2:2:2 . Quantification by absorbance measurement at 307 nm. The Rf value of ofloxacin and tinidazole was found to be 0.12 and 0.85 respectively. Recovery was 99.85 % and 99.45 % for ofloxacin and tinidazole respectively. The proposed method was quantitatively evaluated in terms of calibration of concentration range, stability, and accuracy. It can be adopted for routine analysis of the formulation.
J. Planar Chromatogr. 17, 61-64 (2004). HPTLC of celecoxib and loratadine (as internal standard) on silica gel after prewashing and bandwise application with n-hexane - ethyl acetate 3:2 in a twin-trough chamber and equilibration for 10 min. Quantitative determination at 262 nm. Mean recovery 100.03 %.
J. Planar Chromatogr. 17, 454-458 (2004). HPTLC of lipids and phospholipids (tricylglycerols, free sterols, free fatty acids, steryl esters, phosphatidylcholine, phosphatidylethanolamine) on silica gel with petroleum ether - diethyl ether - glacial acetic acid 80:20:1 in a presaturated twin-trough chamber. Detection by spraying with 5 % phosphomolybdic acid in ethanol, followed by heating for 10 min at 115 °C. The neutral lipids are visible as blue spots on a yellow background. For polar lipid analysis, plates were developed with chloroform - methanol - water 65:25:4 and sprayed with 10 % cupric sulfate, followed by heating for 10 min at 140 °C, to detect phospholipids as brown spots on a white background. Quantitative determination by densitometric analysis at 610 nm for neutral lipids and at 370 nm for polar lipids.
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.
