J. Planar Chromatogr. 19, 73-80 (2006). TLC of six atypical antipsychotic drugs (amisulpride, clozapine, olanzapine, quetiapine, risperidone, ziprasidone) on silica gel, amino, cyano, DIOL, and polyamide phases with mixtures of n-hexane and six polar modifiers (acetone, dioxane, diethylamine, ethanol, isopropanol, and tetrahydrofuran) in a horizontal DS chamber. After development the plates were inspected under UV light at 254 nm. Quantification by densitometry.

J. Sep. Sci. 26, 1698-1700 (2003). HPTLC of levofloxacin and lamotrigine (internal standard) on silica gel with water – methanol – n-butanol 1:1:1 and 1 drop of ammonia. Quantitative determination by absorbance measurement at 298 nm. Linearity of determination of levofloxacin is between 0.8 and 3.0 µg and its average percentage recovery is 99.9 %.

J. AOAC Int. 90, 405-413 (2007). TLC of acediasulfone, cinchocaine and cefuroxime on silica gel with butanol - methanol - tetrahydrofurane - concentrated ammonium hydroxide 10:10:10:1 with chamber saturation. Detection under UV at 254 nm. Quantitative determination by absorbance measurement at 262 nm.

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 The progress of reaction was monitored by Co-TLC of a withdrawn scratch with the starting drug.

Indian Drugs 43 (12), 989-982 (2006). HPTLC of lupeol in a methanolic extract of powdered Vernonia cinerea L. on silica gel with dichloromethane - toluene - acetone - methanol 30:50:5:3. Detection by spraying with anisaldehyde reagent. Quantitative determination by absorbance measurement at 581 nm. The concentration of lupeol in Vernonia cinerea L. was found to be 2.01 µg. The method was validated and can be used for routine quality control of Vernonia cinerea L. including quantitation of lupeol.

Abstract No. F-286, 61st IPC (2009). HPTLC of ambroxol (extracted from plasma with diethylether, after centrifugation the organic layer was evaporated and the residue was taken up in 1 mL of methanol) on silica gel with acetonitrile - methanol - triethylamine 41:5:4. Quantitative determination by absorbance measurement at 254 nm.

J.A.O.A.C. 68, 1232-1234 (1985). TLC of sulfa drugs and their N-methyl derivatives and phototdegradation products on silica with a) chloroform - ethyl acetate - methanol 5:5:1, b) chloroform - methanol 1:1, or upper layer of butanol - acetic acid - water 4:1:5. Detection by spraying with Bratton-Marshall reagent.

Polish J. of Pharmacology and Pharmacy 40, 413-422 (1988). TLC of five carboline derivatives on silica with chloroform - methanol 9:1 or ethyl acetate - methanol 3:1. Detection under UV 254 nm.
