Asian J. Chem. 19(6), 4925 - 4927 (2007). TLC of ezetimibe on silica gel with toluene - acetone 3:2. Quantitative determination by absorbance measurement at 233 nm. The hRf value was 52 for ezetimibe. Linearity was in the range of 300 to 2100 ng/spot. Recovery (by standard addition method) was 99-101 %.

Chinese J. Pharm. (Zhongguo Yaoxue Zazhi) 32, 110-112 (1997). TLC on silica with chloroform - methanol 19:2. Detection under UV 254 nm. Quantification by densitometry at 275 nm. Recovery 97.0 ± 7.8%, n=11).

J. Planar Chromatogr. 21, 343-348 (2008). HPTLC of 12 psychotropic drugs (chloropromazine, perazine, flupentixol, haloperidol, risperidon, alprazolam, midazolam, clomipramine, amitryptyline, doxepin, moclobemide, carbamazepine) on RP-18 in a horizontal chamber. The 10 mobile phases were prepared by mixing different amounts of water and the polar modifiers methanol, dioxane, acetone, acetonitrile, or tetrahydrofuran. Ammonia solution, acetate buffer (pH 4.75), or dodecyl sulfate was added to each of these mixtures. Detection under UV 254 nm.

J. Chromatogr. A 819, 99-111 (1998). 2D-TLC on silica gel with dichloromethane - methanol 49:1 for the 1st direction and dichloromethane - propionic acid 49:1 for the 2nd. Detection by spraying with a mixture of 1) ethanol - propan-2-ol - 25% NH3 25:25:1 and 2) 0.25 g L-cysteine hydrochloride in 4 mL water. Identification by comparison with standards. Confirmation by multiple MS based on the infusion of the remainder of the extract used for TLC via the electrospray interface.

J. Planar Chromatogr. 22, 101-107 (2009). HPTLC of aceclofenac on silica gel (prewashed with methanol) with toluene - ethyl acetate - methanol - glacial acetic acid 70:20:20:1 in a saturated twin trough chamber. Quantitative determination by absorbance measurement at 270 nm. Linearity was between 0.8 and 14 µg/mL. Average relative residual at each calibration point combined with accuracy and precision were compared using the parameter rank approach. The 1/ x 2 weighted regression model provided best estimates with small relative residuals and the best accuracy and precision.

Chromatographia 50 (11/12), 705-709 (2000). TLC on silica gel with acetonitrile - ethyl acetate - propanol - water 17:4:10:10. Detection by dipping into an ethanolic solution of a-naphthol (0.5% m/v) and sulfuric acid 5% and heating at 110°C for 10 min. Quantitation by densitometry.

Abstract No. F-246, 61st IPC (2009). HPTLC of levodopa and carbidopa on silica gel with acetone - chloroform - n-butanol - acetic acid - water 50:45:42:35:25. Quantitative determination by absorbance measurement at 283 nm. The method was linear in the range of 200-700 ng/band for both compounds, with a recovery of 98.7-99.9 %.

Arzneim.-Forsch./Drug Res. 53, 26-33 (2003). 2D- TLC of 14C-SNI-2011(cis-2-methylspiro[1,3-oxathiolane-5,3'-quinuclidine]monohydrochloride hemihydrate, cevimeline) on silica gel with ethyl acetate - methanol - NH3 7:1:1 for the first direction and chloroform - ethanol - water - NH3 22:22:3:2 for the second direction. After development, the plate was covered with a protecting film and contacted on the Imaging Screen. The radioactive image was read by Molecular Imager.
