J. AOAC Int. 79, 1263-1268 (1996). TLC separation of erythromycin, tylosin and 11 other drugs (oxytetracycline, chlortetracycline-HCl, furazolidone, nitrofurazone, nitrofurantoin, sulfathiazole, sulfadiazine, sulfamerazine, amprolium, olaquindox, ronidazole) on silica with chloroform - methanol 10:1 with traces of NH3. Detection under UV 254 and 366 nm; also spraying with 10 % sulfuric acid in ethanol and heating at 120°C for 3 min.

J. Liq. Chrom. Rel. Technol. 27, 2113-2119 (2004). TLC of corrinoid compounds, authentic B12 and cyanocobamides (benzimidazolyl-, 5-hydroxy-benzimidazolyl- and 7-adenylcyanocobamides) on silica gel with 2-propanol - 28% ammonia - water 7:1:2 in the dark at 25 °C. Detection under daylight as pink-colored spots.

J. AOAC Int. 87, 707-717 (2004). TLC of oligosaccharides (produced on hydrolysis of high molecular weight fructan with endo-inulinase) with fructose, glucose, kestose, and kestotetraose with n-propanol - ethanol - water 7:1:2. The plates were developed once, and spots were visualized by spraying the plates with 5 % sulfuric acid in methanol, followed by heating at 120 °C for 5 min.

J. Planar Chromatogr. 19, 58-61 (2006). HPTLC of xanthohumol and isoxanthohumol on silica gel with toluene - dioxane - acetic cacid 77:20:3 in an unsaturated flat-bottomed chamber. Quantification by scanning at 368 nm. The detection limit was 2 ng per spot. The method was validated for precision, accuracy, and repeatability. The method is specific; a linear relationship was obtained between response (peak area) and amount of xanthohumol in the range of 7.7-77 ng per spot; the correlation coefficient was 0.997. Recovery at the three levels was found to be 119.1 %, 95.7 %, and 96.7 %, respectively. Instrumental presision and repeatability were 0.38 and 1.5 %, respectively. Intra-day and Inter-day precision were 1.7 and 2.3 %, respectively.

J. Chromatogr. A 1145 (1-2), 222-228 (2007). Pre-fractionation of cis and trans-fatty acids by silver-ion TLC (Ag-TLC) and other methods (silver-ion SPE (Ag-SPE) or HPLC) allows accurate determination of the isomeric profile but is not essential to achieve quantification of total trans-18:1 isomers nor to determine the level of vaccenic (trans-11 18:1) acid in dairy fat. Comparison of different GLC methods suitable to measure the total of trans-18:1 isomers, vaccenic acid and trans-18:1 acid isomeric distribution in milk fat. Pre-separation of cis- and trans-18:1 isomers by Ag-TLC followed by GLC analysis under optimal conditions was selected as the reference method.
