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.

Thin Layer Chromatographic and densitometric analysis. J. Planar Chromatogr. 20, 209-215 (2007). TLC of phospholipids (with cardiolipin, phosphatidyl ethanolamine plasmologen and phosphatidyl cholin plasmologen as standards) on silica gel, prewashed with chloroform - methanol 2:1 and acetone, using one-dimensional TLC with 1-propanol - chloroform - ethyl acetate - methanol - water 50:50:50:21:18 and two-dimensional TLC with 1-propanol - chloroform - ethyl acetate - methanol - water 50:50:50:21:18 in the first direction and hexane - diethyl ether 1:1 in the second direction after hydrolysis with 1 % hydrochloric acid to reveal alkenylphospholipids. Detection by staining with thionine reagent resp. with leucofuchsin reagent. Densitometric scanning at 600 nm (for thionine) and at 560 nm (for leucofuchsin).

J. Planar Chromatogr. 20, 341-345 (2007). HPTLC of octachlorodipropyl ether on silica gel prewashed with chloroform - methanol 1:1 in an unsaturated twin-trough chamber with toluene - acetic acid - water 20:20:1. Detection by spraying with silver nitrate - 2 M ethanolic potassium hydroxide, followed by heating for 30 min at 120 °C, overspraying with 1 % silver nitrate in 30 % nitric acid, and exposure to UV light for approximately 15 min. Densitometric evaluation of absorbance at 399 nm.

59th Indian Pharmaceutical congress C-305, 297, (2007). Phytoconstituents of mature and immature tubers of Ipomoea mauritiana (methanolic and aqueous extracts) have been studied. HPTLC on silica gel with chloroform - methanol - formic acid 6:3:1. Detection by spraying with vanilin - sulphuric acid reagent. Densitometric evaluation at 365 nm. Mature tubers were found to contain higher concentration of phytoconstiuents than immature tubers.

59th Indian Pharmaceutical congress F-54, 402, (2007). HPTLC of amlodipine besylate and bisoprolol on silica gel with methanol - ethyl acatete - ammonia 1:12:1. Densitometric evaluation at 229 nm. The method was linear in the range of 500-1000 ng/zone. Recovery was 99.9 -101.5 %.

J. Planar Chromatogr. 20, 331-334 (2007). HPTLC of tizoxanide (with nitazoxanide as internal standard) on silica gel prewashed with methanol in a twin-trough chamber with toluene - ethyl acetate - acetic acid 62:134:4. UV detection and quantitation at 313 nm for the internal standard and at 410 nm for tizoxanide.
