J. Planar Chromatogr. 20, 101-106 (2007). TLC of 10 derivatives of N-benzylamides and N-phenylethylamides of alpha-(1,2,3,4-tetrahydroisoquinolin-2-yl)-gamma-hydroxybutyric acid on RP-18 with mixtures of methanol and water after chamber saturation. Visualization under UV light at 254 nm. Retention data obtained by use of this method were linearly dependent on methanol concentration and enabled estimation of relative lipophilicity corresponding to pure water as mobile phase.

J. Planar Chromatogr. 21, 143-149 (2008). RPTLC method for parallel estimation of the lipophilicity of chemically diverse neutral compounds or weak acids and bases. TLC of 28 drugs on RP-18 prewashed with methanol and heated at 160 °C for 1 h, with mixtures of water with methanol, ethanol, 1-propanol, acetone, acetonitrile, and 1,4-dioxane in a saturated chamber. Acetone - water 9:11 and 3:2 were best suited. Densitometric evaluation at 200 and 254 nm.

60th Indian Pharmaceutical Congress PA-194, (2008). HPTLC of bumetanide on silica gel with toluene - ethyl acetate - formic acid 14:7:1. Quantitative determination by absorbance measurement at 335 nm. In the stability test (stress conditions: acid, alkali, oxidation, dry heat, wet heat, photodegradation) the compound was well separated from degradation products. Linearity was in the range of 100 - 800 ng/spot.

60th Indian Pharmaceutical Congress PA-203, (2008). HPTLC of paracetamol and nabumetone in combined tablet dosage form on silica gel with toluene - isopropyl alcohol - acetic acid 80:20:1. Quantitative determination by absorbance measurement at 236 nm. The method was linear in the range of 50-250 ng/spot for both compounds. The method was suitable for routine quality control of tablet dosage form.

J. Liq. Chromatogr. Relat. Technol. 31, 1892-1902 (2008). HPTLC of hydrochlorothiazide, walsartan, kandesartan, and enalapril on silica gel after chamber saturation using ethyl acetate - tetrahydrofuran - acetic acid 16:4:1 (for kandesartan and walsartan present together with hydrochlorothiazide) and 1-butanol - acetic acid - water 12:3:5 (for enalapril and hydrochlorothiazide). Quantitative determination by absorbance measurement at 252 nm for walsartan and kandesartan, at 274 nm for hydrochlorothiazide and at 208 nm for enalapril. The method was of high sensitivity and specific to analyte constituents.

J. Planar Chromatogr. 22, 187-189 (2009). HPTLC of tamoxifen citrate ((Z)-2-[4-(1,2-diphenylbut-1-enyl)phenoxy]ethyldimethylamine citrate) on silica gel (prewashed with methanol - chloroform 1:1) by automated multiple development (AMD 2) using single-step isocratic development with toluene - methanol - glacial acetic acid 57:38:5. Detection under UV 254 nm. Quantitative determination by absorbance measurement at 256 nm. The limit of detection and quantitation was 25 and 52 ng/band, respectively.

J. Planar Chromatogr. 21, 271-275 (2008). HPTLC of capsaicin and its degradation products (after acidic and alkaline hydrolysis, oxidation and thermal degradation) on silica gel with toluene - ethyl acetate 3:2. Quantitative determination by absorbance measurement at 280 nm. The limit of detection and quantification was 10 and 60 ng/band, respectively.

60th Indian Pharmaceutical Congress PA-220 (2008). HPTLC of domperidone and esomeprazole on silica gel with chloroform - methanol 9:1 with chamber saturation for 30 min. The hRf value was 25 for domperidone and 46 for esomeprazole. Quantitative determination by absorbance measurement at 295 nm. The method was linear in the range of 60-300 ng/spot for domperidone and 80-400 ng/spot for esomeprazole.
