J. Planar Chromatogr. 18, 319-322 (2005). HPTLC of emodin and phenolic acids (protocatechuic, homoprotocatechuic, caffeic, syringic, vanillic, ferulic, p-hydroxyphenylacetic, alpha-resorcylic, p-coumaric, gallic and ellagic acid) on silica gel in horizontal chambers with toluene - dichloromethane - ethyl acetate 4:4:1. Also two-dimensional TLC of phenolic acids on cellulose with benzene - methanol - acetic acid - acetonitrile 16:2:1:1 in the first direction and sodium formate - formic acid - water 10:1:200 in the second direction. After drying the chromatograms were observed under UV light at 254 nm before and after treatment with ammonia vapor. Derivatization was performed by spraying with either diazotized sulfanilic acid in 20 % sodium carbonate solution or with 2 % aqueous iron(III) chloride. Detection limits between 10 and 64 ng. Videodocumentation and quantitation by densitometry.

J. Planar Chromatogr. 21, 39-42 (2008). HPTLC of neutral lipids and ubiquinone on silica gel with petroleum ether - diethyl ether - acetic acid 80:20:1. Detection with phosphomolybdic acid reagent. Quantitative determination by densitometry at 610 nm. Specific detection reagents were used to confirm the identity of particular lipid classes. The studies confirmed the presence of free sterols, free fatty acids, methyl esters, hydrocarbons and ubiquinone, and triacylglycerols.

J. Liq. Chromatogr. Relat. Technol. 33, 1013-1027 (2010). Preparative TLC of triacylglyerol (TAG) fractions on silica gel with hexane - acetone 25:4. Analytical TLC of TAG classes from sunflower, corn, soybean, cotton, and olive oil (differing in saturation) on silica gel, impregnated by dipping into a 5 % methanolic solution of silver nitrate, with petroleum ether - acetone - ethyl acetate 100:3:2 and 50:3:2. Detection by exposure to bromine and sulfuryl chloride vapor and heating at 180-200 °C . Quantitative determination by absorbance measurement at 450 nm.

In. Arch. Otorhinolaryngol. 19, 141-150 (2015). HPTLC of the lipids lactosylceramide (1), triacylglycerol (2), phosphatidylcholine (3), cholesterol (4) and sphingomyelin (5) in mastoid tissue on silica gel with chloroform - methanol - water 65:25:4. Detection of lipids by spraying with orcinol reagent (0.02 % in 50 % sulfuric acid) followed by heating at 120 °C for 2-3 minutes. Additional detection with Coomassie Brilliant Blue (0.03 % in 30 % methanol/100 mM sodium chloride) followed by methanol 30 % in 100 mM sodium chloride for destaining. The hRF value was 24-47 for (1) and (5), 71-100 for (2) and (4), and 0-24 for (3). Combination with gas chromatography/electron impact-mass spectrometry revealed the presence of cholesterol and several fatty acids. Combination with flow-injection/electrospray ionization-tandem mass spectrometry revealed a host of phosphatidylcholines, phosphatidylethanolamines, and cholesteryl esters.
