Asian J. Chem. 20(7), 5409 - 5413 (2008). HPTLC of atomoxetine HCl on silica gel with acetonitrile - acetic acid 9:1. Quantitative determination by absorbance measurement at 269 nm. The method was linear in the range of 100-1000 µg/mL. The recovery was 99.8 %. The method was suitable for routine analysis of atomoxetine HCl in its pharmaceutical preparations.

62nd Indian Pharmaceutical Congress Abstract No. F-253 (2010). TLC of ambroxol hydrochloride and doxophylline on silica gel with n-butanol – toluene – ethyl acetate – 25 % ammonia 50:30:20:1. The hRf values were 36 and 45 for doxophylline and ambroxol, respectively. Quantitative determination by absorbance measurement at 258 nm. The method was linear in the range of 300-1100 ng/band for ambroxol and 100-1100 ng/band for doxophylline.

Food Control. 68, 220-228 (2016). HPTLC of biogenic amines (putrescine, histamine, tyramine and agmatine) in microbial cultures on silica gel with chloroform – benzene – triethylamine 12:9:2. Quantitative determination by absorbance measurement at 254 nm.

J. of Medicinal Chemistry 32, 297-301 (1989). TLC of N- (dipeptidyl)-S-acetylcysteamine and N, N’- (dipeptyl)cystamine on silica. Detection under UV, exposure to iodine vapor or spraying with ninhydrin.

Talanta 38, 1303-1307 (1991). Use of o-phthalaldehyde in sulfuric acid solution as spray reagent in TLC of some tryptophan derived indole alkylamines on silica with ethyl acetate - propan-3-ol - conc. NH3 45:35:20. Detection limits, from 20 to 100 ng per spot. Application examples.

Proc. 9th Internat. Symp. Instr. Chromatogr., Interlaken, April 9.-11., 47-68 (1997). Measurement of retention data (expressed as the logarithm of capacity factors, log k') for twelve test alkanolamines indicating lysosomotropic activity in eighty planar chromatography systems employing eight different silica gel layers with varied chemically bonded phases. Aqueous binary mobile phases containing methanol or acetonitrile as organic modifier in five different proportions were applied in TLC experiments.

J. Planar Chromatogr. 14, 21-23 (2001). TLC of the DIPABTC derivatives of eight monoamines (adrenaline, b-phenylethylamine, histamine, noradrenaline, octopamine, serotonin, and tyramine) on silica gel in a horizontal chamber at 24°C with 15 mobile phases. Higher sensitivity was achieved when the colored derivatives were placed in HCl vapor resulting in deep red-brown spots. Simple and quick TLC method using a newly synthesized derivatization reagent.

J. Liq. Chromatogr. & Relat. Technol. 29, 2425-2436 (2006). HPTLC and TLC of phenyl isothiocyanate derivatives of biogenic amines (2-phenylethylamine, tyramine, octopamine, dopamine, adrenaline, histamine, tryptamine, putrescine, spermidine, spermine, and calamine) on silica gel and RP-18 in a horizontal chamber saturated for 30 min with hexane - dioxane 1:1; 1:2; and 2:3; hexane - ethanol 1:1, methanol - dioxane 2:1, and hexane - dioxane - toluene 1:1:1. Prechromatographic derivatization with PITC directly on the plate. Detection of NP-TLC plates (silica gel) by spraying with a mixture of sodium azide and starch solution. For RP-TLC sodium azide solution with starch was incorporated into the mobile phase, and then the plates were exposed to iodine vapor. The stability of the resulting white zones on a violet-grey background lastet for several minutes. The results of the detection limits proved to be advantageous to other commonly used detection techniques (UV and iodine chamber).
