J. Pharm. Biomed. Anal. 43 (3), 839-844 (2007). HPTLC of artemether both as a bulk drug and in pharmaceutical formulations on silica gel aluminum plates with toluene - ethyl acetate - formic acid 80:20:3. Quantification of artemether by densitometry at 565 nm. Linearity was between 200 and 1000 ng/spot. The limit of detection and quantification was 65 and 197 ng/spot, respectively. The method was successfully applied in the analysis of lipid based parenteral formulations and marketed oral solid dosage formulation.
J. Liq. Chromatogr. Relat. Technol. 31, 1959-1968 (2008). Quantitative Ag-TLC of eight samples of sunflower oil with different linoleic acid content on silica gel (impregnated by dipping into a 0.5 % methanolic solution of silver nitrate) with petroleum ether - acetone 25:1, and petroleum ether - acetone - ethyl acetate 100:5:2, and 50:3:2. Detection by consecutive treatment with bromine and sulfurylchloride vapors (30 min each) followed by heating at 180-200 °C. Quantitative determination by absorbance measurement at 450 nm. Evaluation of authenticity and possible adulteration of edible oils.
J. Liq. Chromatogr. Relat. Technol. 30, 2617-2628 (2007). TLC and HPTLC of monoterpenes, e. g. menthol and menthone from peppermint, on silica gel with toluene - ethyl acetate 3:7, 4:6, ... , 9:1, and 10:0 in a horizontal chamber. Detection with methanolic vanillin - sulfuric acid reagent and under UV 254 nm. Flavonoids from hawthorn, Passiflora incarnata, hop, cacao, as well as tea were also determined by TLC and OP TLC.
Biochem. Biophys. Res. Commun. 372, 480-485 (2008). 2D-TLC of alpha-32P ATP or alpha-32P UTP labeled nucleotides after RNase T2 treatment of tRNA transcripts synthesized by T7 RNA polymerase, on silica gel with isobutyric acid – ammonia – water – 66:1:33 for the first dimension and isopropyl alcohol – hydrocloric acid – water 14:3:3 for the second dimension. Quantitative determination by radioactivity measurement of the labeled nucleotides.
Asian J. Chem. 19(5), 3375-3381 (2007). The TLC method described in USP 28 does not separate all the related substances of alprazolam. An alternative HPTLC method is described for separation and estimation of starting material and synthesis related intermediates in alprazolam: 2-chloro acetamide-5-chloro benzophenone (impurity 1) i.e. starting material, nordiazepam (impurity 2), thionordiazepam (impurity 3), 2-(2-aceto hydrazinyl)-7-chloro-5-phenyl-3H-1, 4-benzodiazapine (impurity 4). The hRf values of alprazolam, impurity 4, impurity 3, impurity 2, and impurity 1 were 25, 16, 77, 45, and 83 respectively. The HPTLC method developed is capable of detecting impurities at a level of 0.05%.
Asian J. Chem. 19(5), 3918-3922 (2007). TLC of paracetamol and aceclofenac on silica gel with toluene - isopropyl alcohol - ammonia 20:20:3. Quantitative determination by absorbance measurement at 254 nm. Linearity was between 60 and 140 µg/mL for aceclofenac and 460 and 540 µg/mL for paracetamol. Recovery (by standard addition method) of paracetamol and aceclofenac was between 98.6 and 99.3 %. The proposed method was found to be accurate, precise, simple and rapid could be used for routine analysis.
J. Liq. Chromatogr. Relat. Technol. 30, 2755-2767 (2007). HPTLC of satranidazole (3-(1-methyl-5-nitroimidazol-2-yl)-1-(methylsulfonyl)imidazolidin-2-one) on silica gel (prewashed with methanol) with toluene - acetonitrile 3:2 in a twin-trough chamber saturated for 30 min at 25 °C. Quantitative determination by absorbance measurement at 314 nm. The method can effectively separate the drug from its degradation products and is therefore suitable for stability studies.
Asian J. Chem. 1, 509-513 (2008). HPTLC of andrographolide in Andrographis paniculata homoeopathic mother tincture on silica gel with chloroform - methanol 7:1. Quantitative determination by absorbance measurement at 225 nm. The standard mother tincture was found to contain 21.9 mg/100 mL andrographolide, where as 6 commercial samples contained varying amounts of andrographolide ranging from 4.89-54.62 mg/100 mL.
