HPTLC of steryl esters, methyl esters, triacylglycerols, FFA, and free sterols on silica gel (prewashed by development with dichloromethane -methanol 1:1) with petroleum ether - diethyl ether - glacial acetic acid 80:20:1 in a saturated twin-trough chamber. Detection by spraying with 5 % ethanolic phosphomolybdic acid followed by heating at 150 °C for 110 min. Quantitative determination by absorbance measurement at 610 nm.

J. Liq. Chromatogr. Relat. Technol. 31, 1959-1968 (2008). Quantitative Ag-TLC of eight samples of sunflower oil with different linoleic acid content on silica gel (impregnated by dipping into a 0.5 % methanolic solution of silver nitrate) with petroleum ether - acetone 25:1, and petroleum ether - acetone - ethyl acetate 100:5:2, and 50:3:2. Detection by consecutive treatment with bromine and sulfurylchloride vapors (30 min each) followed by heating at 180-200 °C. Quantitative determination by absorbance measurement at 450 nm. Evaluation of authenticity and possible adulteration of edible oils.

J. Liq. Chromatogr. Relat. Technol. 32, 1289-1298 (2009). HPTLC of phosphatidylcholine (1), phosphatidylethanolamine (2), sphingomyelin (3), sulfatides (4), and cerebrosides (5) in tissue samples of the lizard Uta stansburiana on silica gel with chloroform - methanol - water 65:25:4. Detection by spraying with 10 % cupric sulfate in 8 % phosphoric acid, followed by heating at 140 ºC for 30 min. Quantitative determination by absorbance measurement at 370 nm. The hRf values of (1)-(5) were 40, 56, 39, 51 and 71, respectively.

PLoS ONE 8(11), e80841 (2013). On silicic acid columns, total ceramides, from methanol – chloroform extracts of mouse tissue (brain, heart, liver) and of cell cultures (astrocytes, oligodendroglia) were purified from other lipids (phospholipids, sphingoid bases, glycosphingolipids, retained on the column) and fractioned using chloroform – acetone – acetic acid 24:1:0.01 followed by chloroform – acetone – acetic acid 18:2:0.01. For the monitoring, TLC of fractions (layer not specified) with chloroform – methanol – acetic acid 190:10:1. After derivatization by iodine vaporization or by spraying with copper sulfate reagent (copper(II) sulfate 20 mM - sulfuric acid 5 % - ammonium molybdate 1 %), lipids are detected as orange or brown-black zones, respectively. The aforesaid fractionation allowed the isolation of hydroxyl-fatty-acyl ceramides, phytoceramides, non-hydroxy-fatty-acyl ceramides and cholesterol (identification by comparison to standards and by GC-MS); their hRf values were between 40 and 80. Quantitative determination by densitometric measurement. This is the first report of phytoceramide identified in vertebrate brain, heart and liver.

CBS 117, 11-12 (2006). For the rapid control of the fish species escolar (Lepidocybium flavobrunneum) by determination of the indigestible wax esters, HPTLC on silica gel with n-hexane – toluene 7:3 with chamber saturation for 10 min, migration distance 60 mm. Detection by dipping in aqueous Rhodamine B reagent (0.025 %), evaluation under UV 366 nm. Quantitative determination by fluorescence measurement at 366/>400 nm with the Hg lamp. The hRF value of oleyl oleate was 30 and of stearyl stearate 40. The mean recovery rate (104 %) was determined by analyzing salmon samples spiked to contain 20 % wax esters. The wax ester content of an escolar sample was 18-22 % (n=3). The repeatability was <5 % and the mean laboratory precision 3 %.

Lipids 17, 650-655 (1982). For preparative separation silica plates were used with hexane - ether 6:4. For separation of hydrogenated oils into their various components, multiple development (4 or 5x) TLC was carried out with ether - benzene 1:99 followed by ether - benzene 3:97. Analytical TLC components were visualized by charring with sulfuric acid-dichromate or with iodine vapors. reparative TLC: bands were located by spraying with ethanolic dichlorofluorescein, followed by viewing under UV. The components of the seed oil of trewia nudiflora and mallotus phillipinensis were chromatographed and compared.
