Microtechniques. J. Planar Chromatogr. 2, 389-391 (1989). HPTLC separation of neutral lipids, cholesteryl esters, and phospholipids on silica with carbon tetrachloride - propanol - ethyl acetate - chloroform - methanol - ethanol - 43 mM potassium chloride 23:23:29:11:12 or chloroform - methyl acetate - ethyl acetate - methanol - hexane 2000:15:30:30:15 as mobile phases; detection by spraying with phosphomolybdic acid or copper(II)sulfate reagent followed by heating at 100-150 °C for 2-5 min. The methods described allows the determination of 21 different components within 15 min.

(Hungarian). Gyógyszerészet 34, 349-358 (1990). TLC of ergometrine, agroclavine, chanoclavine, elymoclavine, penniclavine and D-lysergicacidamine on silica with chloroform – methanol 8:2 and chloroform – diethylamine 9:1. Visualization under UV 254 and 366 nm. Quantification by densitometry.

J. Planar Chromatogr. 3, 269-271 (1990). HPTLC separation of saturated, monoenoic and dienoic fatty acid methyl esters and corresponding fatty acid dimethylacetals on silica, prepared with 10% AgNO3, and chloroform - methanol 99:1, 95:1. Visualization by spraying with 2',7'-dichlorofluorescein and visualization under UV. Reverse phase TLC can be as effective as HPLC for the investigation of fatty acid metabolism but is more rapid and more suitable for analyzing multiple radioactive samples.

J. Chromatogr. 547, 531-537 (1991). TLC of phenylalanine, tryptophan and tyrosine on cellulose with 0.7M sodium sulfate in water. Optimization of the sodium sulfate concentration of the mobile phase. Detection by spraying with 0.3 g ninhydrin in 100 mL acetone and heating at 110°C for 15 min. Quantification by densitometry at 565 nm.

J. Planar Chromatogr. 5, 131-133 (1992). TLC of rhamnose, xylose, arabinose, mannose, glucose, galactose, glucuronic acid, galacturonic acid on silica impregnated with phosphate buffer (0.2M, pH 6.8) with acetonitrile - amyl alcohol - water 6:2:2. Detection by spraying with a solution of N-(1-naphthyl)ethylene diamine dihydrochloride (30 mg in 10 mL of a solution of 5 % sulfuric acid in methanol) followed by drying for 10 min at 100 °C. Quantification in the nanogram range by densitometry at 580 nm.

J. Chromatogr. 614, 315-323 (1993). TLC of diethylstilbestrol and zeranol on silica with dichloromethane - methanol - 2-propanol 97:1:2. Visualization with iodine - starch, or by spraying with 0.05% aqueous solution of diazonium dyes, and exposure to NH3 vapor for 30 sec and heating at 80 °C for 2 min.

Biomed Chromatogr. 8, 69-72 (1994). TLC of a mixture of 18 PTH amino acids on silica with 1) pyridine - benzene 5:40, 2) methanol - carbon tetrachloride 1:20, 3) acetone - dichloromethane 3:80. Detection by exposure to iodine vapor. Using the systems, various combinations of PTH amino acids which had previously posed resolution problems have been resolved and identified.
