Anal. Biochem. 269, 304-311 (1999). HPTLC of total urinary lipids on silica gel with chloroform - methanol - water 65:25:4. The chromatogram was first sprayed with primuline, and sphingomyelin was determined fluorometrically at 365 nm/>400 nm. Subsequently, sulfatides were stained with azure A or orcinol. Densitometry in reflection mode at 610 or 546 nm, respectively.

J. Chinese Trad. Patent Med., (Zhongchengyao) 25(5), 428-429 (2003). TLC on silica gel with 1) toluene - ethyl acetate - formic acid 15:2:1; 2) petroleum ether (60-90°C) - ethyl acetate 4:1; 3) petroleum ether (60-90°C) - ethyl acetate 7:3; 4) benzene - ethyl acetate - acetic acid 18:1:1. Detection 1) by exposure to ammonia vapor; 2) under UV. Identification of by finger print technique. Discussion of use of the procedure for the rapid quality control of the medicine.

J. Chromatogr. B 857 (2), 337-340 (2007). OPLC of basic drugs in autopsy liver samples prepared by enzymatic digestion with trypsin and liquid - liquid extraction with butyl chloride. Separation by dual-plate analysis with trichloroethylene - methyl ethyl ketone - n-butanol - acetic acid - water 17:8:25:6:4 for OPLC 1 and butyl acetate - ethanol (96.1 %) - tripropylamine - water 340:37:20:3 for OPLC 2. Identification by automated comparison of corrected hRf values and in situ UV spectra with library values by dedicated software. Determination of the identification limit for 25 basic drugs in liver ranging from 0.5 to 10 mg/kg. The method is suitable for routine screening of basic drugs in post-mortem samples of varying quality, combining the benefit from moderately high separation power with the ease of disposable plates.

59th Indian Pharmaceutical Congress F-94, 413, (2007). HPTLC of escitalopram oxalate and clonazepam in combined tablet dosage form on silica gel aluminium plate with toluene - ethyl acetate - triethylamine 7:3.5%:3. Quantitative determination by densitometric scanning at 258 nm. The calibration curve was linear over a range of 250 and 2500 ng/zone for escitalopram oxalate, and 50 and 500 ng/zone for clonazepam.

Lipids 17, 469-475 (1982). The total methyl esters of the fatty acids of tissue glycerides were converted into methoxy-acetoxy-mercury adducts. The adducts were fractionated into groups of equal numbers of ethylenic bands on silica with hexane - dioxane 6:4. Separation of the monoethylenic acids of equal chain length into the respective cis-and trans isomers by TLC on AgNO3-silica, acc. to known procedure.

59th Indian Pharmaceutical congress F-173, 431, (2007). HPTLC of famotidine and domperidone on silica gel with ethyl acetate - methanol - toluene - ammonia 40:15:20:2. Densitometry at 285 nm. Linearity was between 100 and 600 ng/µL for both compounds. Limit of detection and quantification was 33 and 100 ng/zone, respectively. Recovery was 99.5 %.

(Screening of halazepam, a new antianxiety agent.) Fresenius Z. Anal. Chem. 321, 359-362 (1985). Use of TLC as a sensitive screening method for 1,4-benzodiazepine derivative (halazepam). After hydrolysis TLC of 2 (2,2,2-trifluoroethyl) amino-5-chloro-benzophenone on silica with toluene. After photolytic desalkylation and diazotation spraying with Bratton-Marshall reagent.

59th Indian Pharmaceutical congress F-8, 397, (2007). HPTLC of atomoxetine on silica gel with acetonitrile - methanol - toluene 2:4:1. Quantification by densitometry at 215 nm. The method was linear in the range of 100 and 310 ng/mol. Mean recovery was 101.3 %.
