J. Planar Chromatogr. 19, 454-462 (2006). HPTLC of enrofloxazine, norfloxazine, oxytetracycline, trimethoprim, sulfamethazine, sulfadiazine, and penicillin G/procaine on cyano phase with 0.05 M oxalic acid - methanol 81:19. Evaluation under UV light at 254 and 366 nm. Quantitative determination of TMP by absorbance measurement at 254 nm, and fluorescence measurement at 366 nm for the other compounds. The SPE-TLC determination was validated for linearity, precision, quantification, and detection limit.

J. Planar Chromatogr. 19, 355-360 (2006). OPLC of paracetamol, acetylsalicylic acid and caffeine on HPTLC silica gel (prewashed with acetonitrile - water 17:3) with n-hexane - toluene - diethyl ether - glacial acetic acid - methanol 100:50:30:19:1 and toluene - diethyl ether - glacial acetic acid - methanol 50:30:19:1. Quantitative determination by absorbance measurement at 254 nm.

Indian Drugs 44 (2), 111-116 (2007). HPTLC for simultaneous determination of mosapride citrate and pantoprazole from pharmaceutical formulations by using loratadine as an internal standard. HPTLC on silica gel with toluene - acetone - methanol 16:4:1. Quantitative determination by absorbance measurement at 254 nm. Mosapride citrate response was linear over the range 0.075 - 0.225 µg/mL, and that for pantoprazole was 0.2 - 0.6 µg/mL. Recovery was 99.6 - 101.3 % for both compounds. The developed method was validated regarding accuracy, precision, and stability, and can be used for routine quality control of formulations containing mosapride citrate and pantoprazole.

Indian Drug 44 (2), 122-127 (2007). HPTLC of ayurvedic medicated oil on silica gel in a twin-trough chamber with ethyl acetate - toulene 1:9 for fingerprint analysis, and ethyl acetate - methanol - water 200:27:20 for quantitative determination of colchicine.

Chromatographia, 66 (1-2), 95-102 (2007). Description of two sensitive and reproducible methods for the quantitative determination of dasatinib in the presence of its degradation products. HPTLC on silica gel with toluene - chloroform 7:3, followed by densitometric measurement at 280 nm. Validation of both separation methods according to ICH guidelines, no interference from the tablet excipients was found. Discussion of application of the methods as the stability indication because the proposed analytical methods could effectively separate the drug from its degradation products, which was subjected to acid–alkali hydrolysis, oxidation, dry heat, wet heat and photo-degradation.

J. Planar Chromatogr. 20, 141-143 (2007). TLC of methyl, ethyl, propyl p-hydroxybenzoate, p-hydroxybenzoic acid, benzoic acid, sodium benzoate, butylated hydroxyanisol, and butylated hydroxytoluene on the inorganic ion exchanger stannic silicate in a twin-trough chamber with n-hexane - ethyl methyl ketone - acetic acid 80:20:3. Quantitation by scanning densitometry at 260 nm.

J. Planar Chromatogr. 20, 419-421 (2007). HPTLC of tricyclazole, thiram, and folpat on silica gel prewashed with methanol, with hexane - acetone 3:2 in an unsaturated twin-trough chamber. Densitometric evaluation at 235 nm. The limit of detection was 12, 30, and 40 ng/zone, for tricyclazole, thiram, and folpat respectively.

CBS 97, 9-11 (2006). HPTLC of trigonelline in fenugreek (Trigonella foenum-graecum) on silica gel in a saturated twin-trough chamber with n-propanol - methanol - water 4:1:4 over 80 mm. Quantitative determination by absorbance measurement at 269 nm. The hRf value of trigonelline was 46 and selectivity regarding matrix was given. Linearity was between 100 and 1200 ng/zone. The inter- and intraday precision was below 1 %. The limit of detection and quantification was 2.3 and 7.6 ng/zone, respectively. Recovery (by standard addition) was 99 - 101 %.
