J. Planar Chromatogr. 17, 454-458 (2004). HPTLC of lipids and phospholipids (tricylglycerols, free sterols, free fatty acids, steryl esters, phosphatidylcholine, phosphatidylethanolamine) on silica gel with petroleum ether - diethyl ether - glacial acetic acid 80:20:1 in a presaturated twin-trough chamber. Detection by spraying with 5 % phosphomolybdic acid in ethanol, followed by heating for 10 min at 115 °C. The neutral lipids are visible as blue spots on a yellow background. For polar lipid analysis, plates were developed with chloroform - methanol - water 65:25:4 and sprayed with 10 % cupric sulfate, followed by heating for 10 min at 140 °C, to detect phospholipids as brown spots on a white background. Quantitative determination by densitometric analysis at 610 nm for neutral lipids and at 370 nm for polar lipids.

Juss) as determined by a combination of chromatographic and spectral techniques. J. Liq. Chromatogr. & Relat. Technol. 30,11-25 (2007). TLC on silica gel with petroleum ether - acetone 25:2; detection by spraying with 50 % ethanolic sulfuric acid and heating at 200°C. Isolation, purification and quantification of lipid classes by preparative TLC; detection by spraying the edges with 2’,7’-dichlorofluorescein for visualization under UV. Preparative separation of acylglycerols, free fatty acids, and polar lipids on silica gel with petroleum ether - acetone - acetic acid 70:30:1. Quantitative Ag-TLC on silica gel impregnated by dipping into a 0.5 % methanolic silver nitrate solution - also preparative Ag-TLC. Quantitative TLC on RP by densitometry at 450 nm. Ag-TLC provided the quantitative data for the TAG classes differing in unsaturation, and RP-TLC for the TAG species differing in chain length within a given class.

J. Agric. Food Chem. 56, 7644-7648 (2008). HPTLC of ferulic acid from agricultural waste (maize bran, rice bran, wheat bran, wheat straw, sugar cane baggasse, pineapple peels, orange peels and pomegranate peels) on silica gel with benzene - dioxane - acetic acid 85:15:1. Detection under UV 254 nm. Purification by adsorption chromatography followed by preparative layer chromatography.

CBS 106, 7-10 (2011). HPTLC of sucralose on silica gel (pre-washed by development with methanol, followed by drying at 100 °C for 15 min) with isopropyl acetate – methanol – water 15:3:1 up to 60 mm (migration time 15 min). Detection by dipping in aniline diphenylamine o-phosphoric acid reagent followed by heating at 120 °C for 20 min, evaluation under white light and UV 366 nm. Quantitative determination by absorbance measurement at 400 nm. Via the TLC-MS Interface the respective zones were eluted and transferred into a single-quadrupole mass spectrometer. Electrospray ionization mass spectra were recorded in full scan mode. The recovery of sucralose in drinking water was 84 ± 7 % (n=3). The limit of detection was 6 ng/band. The calibration curve (10-300 ng/band, r=0.9999, 1.3 %RSD) was suited to analyze sucralose at concentrations of 0.1-5 µg/L.
