J. Chil. Chem. Soc. 59, 2405-2408 (2014). HPTLC of trazodone in human serum on silica gel with toluene - acetone - ethanol - ammonium 18:14:4:1. Quantitative determination by absorbance measurement at 290 nm. The hRF values of trazodone and its metabolite were 82 and 39, respectively. Linearity was between 0.2 and 2 ng/zone. The intermediate intra-day and inter-day precisions were below 3.5 % (n=3). The LOD and LOQ were 16 and 48 pg/zone, respectively. Recoveries for trazodone were in the range of 94.7-99.0 %.

59th Indian Pharmaceutical congress F-152, 426, (2007). HPTLC of rosiglitazone on silica gel aluminum layer with chloroform - ethyl acetate - ammonia 70:30:1. The hRf value of rosiglitazone was 40. Densitometric analysis in absorbance mode at 230 nm. Linearity was between 100 and 1000 ng/zone. Recovery (by standard addition method) was 99.6 %. Limit of detection and quantification was 10 ng and 50 ng/zone, respectively.

Pharm. (Yaoxue Tongbao) 19, 343-345 (1984). (Chinese) (Compatibility of gentamycin and An Tong Dang injection.) TLC of the mixture of gentamycin and An Tong Dang injection showing that no chemical reaction occurs between them. (An Tong Dang contains aminopyrine and antipyrine).

J. Planar Chromatogr. 20, 373-380(2007). Investigation of the chromatographic behavior of the phenolic drugs niclosamide, hexachlorophene, ibuprofen, pentazocine, ethamivan, bithionol, salicylanilide, caffeic acid, p-coumaric acid, 4-aminosalicylic acid, ferrulic acid, and methyldopa on RP-8 and RP-18 phase prewashed with methanol, with methanol - water mixtures in different volume proportions, with chamber saturation for 20 min.The results calculated using seven different software products indicate, that chromatographic lipophilicity can be used as a measure of the lipophilicity of the compounds investigated. Spectra were acquired with the densitometer in absorbance mode. Densitometric scanning was performed at the respective absorption maxima.

Biochem. J. 249, 351-356 (1988). TLC of fatty acid methyl esters on silica impregnated with 10% silver nitrate with hexane - ether 17:3 for the separation of dienes from trienes.
