J. Planar Chromatogr. 11, 47-50 (1998). HPTLC of lipids (cholesterol, oleic acid, triolein, methyl oleate, cholesteryl oleate as standard) on silica gel with hexane - ether - acetic acid 40:10:1. After drying at 115°C for approx. 15 min the lipids were detected as blue spots on a yellow background by spraying with 5% ethanolic phosphomolybdic acid and heating for 15 min at 115°C. Quantitation by densitometry at 700 nm.

Detection with anisaldehyde. Blotting of the separated compounds to a polyvinylidene difluoride membrane, and analyzing them by 1) direct desorption from the membrane fast atom bombardment mass spectroscopy (FAB MS), by 2) membrane-binding assay using NeuAca3- and NeuAca6-specific lectins, and by 3) TLC binding assay with radiolabeled bacteria.

J. Chromatogr. Sci. 39 (7), 293-296 (2001). Presentation of a procedure combining TLC with microliquid extraction as a psychotropic drug testing method for hair, involving some widely distributed antidepressants, neuroleptics, and sedative drugs. Optimization of the experimental conditions for all of the consequent steps for the screening detection of the model samples. Use of the procedure for a fast and cost-effective analysis of abuse.

J. Planar Chromatogr. 30, 299-306 (2017). HPTLC of itopride (1), pantoprazole (2), and mosapride (3) in human plasma on silica gel with methylene chloride ‒ ethyl acetate ‒ methanol ‒ 25 % ammonia 60:10:4:1. Quantitative determination by absorbance measurement at 289 nm. The hRF values for (1), (2) and (3) were 22, 41 and 62, respectively. Linearity was between 100 and 1500 ng/zone for (1) and (3), and between 70 and 1500 ng/zone for (2). The intermediate precision (n=3) was <2 % for (1) to (3). LOD and LOQ were 33 and 98 ng/mL for (1), 17 and 51 ng/mL for (2) and 30 and 91 ng/mL for (3). Average recovery rate was 99.2 % for (1), 99.1 % for (2) and 99.6 % for (3).

J. Chromatogr. 345, 111-118 (1985). TLC of salbutamol on silica with a) chloroform - ethyl acetate 6:4, b) ethyl acetate - chloroform - methanol 60:40:1 after derivatization by reaction with dimethyl-p-phenylene-diamine. Detection and quantification by densitometry at 650 nm. Detection limit 20 ng/ml urine or 1 ng/ml plasma. Results were in good agreement with those obtained by GC/MS.
