J. Planar Chromatogr. 10, 281-285 (1997). Introduction of novel software for the processing of qualitative data from two parallel TLC analyses simultaneously, based on the comparison of libraries of corrected RF values and in situ UV spectra. The essential part of the program is the combination report which lists the substances found on both systems. TLC of codeine, promazine, clomipramine, cocaine on silica with toluene - acetone - 94% ethanol - 25% NH3 45:45:7:3 and of hydroxyzine, lidocaine, codeine, and morphine on RP-18 silica with methanol - water - 37% hydrochloric acid 50:50:1. Densitometry by absorbance at 220 nm and measurement of spectra at 190-400 nm. Also published in Proc. 9th Internat. Symp. Instr. Chromatogr., Interlaken, April 9.-11., 213-221 (1997).

Anal. Biochem 271, 186-187 (1999). Staining of phospholipids, diacylglycerides, free fatty acids, triacylglycerides, cerebrosides, sulfocerebrosides and cholesterol with 26 water soluble organic colors, after TLC on silica. Most sensitive stain with 0.2% amido black 10B in 1 M NaCl: After pre-soaking in water, the chromatogram was immersed in the staining solution for 5 - 10 min. The sensitivity is about 15 ng of diacylglycerides, triacylglycerides, and phosphatidylserine; 100 ng of free fatty acids, and 500 ng of phorbol esters.

Indian Drugs 38 (10), 542-542 (2001). TLC hydrolyzed extract mixture on silica gel (impregnated with boric acid and activated) with acetic acid - chloroform - water 8:5:1. Detection by spraying with aniline phthalate reagent. TLC of two selectively hydrolyzed fractions on silica gel with acetonitrile - water 17:3. Detection by spraying with sulfuric acid - water 1:3 and heating. Presence of b-galactose and fructose was confirmed.

A review with 22 references on TLC-bioautography, including the screening of natural compounds with antibacterial and/or antifungal activity, cholinesterase inhibitors, free radical eliminators, and antioxidants. Discussion of the advantages of the technique compared to other related techniques.

J. Proteome Res. 14, 567-577 (2015). HPTLC of (1) lipids and (2) cholesterol from urinary exosomes on silica gel predeveloped in chloroform - methanol 1:1. (1) was developed with with two mobile phases: chlorofom - ethanol - triethylamine - water 30:35:35:8, and hexane - ether 200:9; (2) with chloroform - acetone 19:1. Detection by dipping in 10 % copper sulfate followed by heating at 185 °C for 5 min.

J. Planar Chromatogr. 20, 457-461 (2007). HPTLC of rivastigmine ((-)-S-N-ethyl-3-[(1-dimethylamino)ethyl]-N-methylphenylcarbamate) and impurity on silica gel with chloroform - methanol 2:3 in a twin-trough chamber with chamber saturation for 30 min. Densitometric analysis was performed in absorbance mode at 210 nm. Limits of detection were 30 and 100 ng/zone, respectively.
