J. Planar Chromatogr. 10, 243-250 (1997). TLC of sebaceous neutral 14C-lipids (squalene, sterol esters, waxes, triglycerides, free fatty acids, and free sterols) on silica with concentration zone; first run to 15.5 cm with hexane - ether - acetic acid 80:20:1, second run to 19 cm with hexane to separate squalene and internal standard. Direct quantification in the range of 20-2000 disintegrations/min (dpm) is performed by radioscanning.

(Trematoda). J. Planar Chromatogr. 12, 306-308 (1999). HPTLC of neutral lipids (cholesteryl oleate, methyl oleate, triolein, oleic acid, cholesterol as standard) on silica gel with petroleum ether - ether - acetic acid 80:20:1. Detection by spraying with 5% ethanolic phosphomolybdic acid and heating at 110°C for 15 min. Densitometry at 700 nm.

Bol. Soc. Chil. Quim. 47, 61-66 (2002). HPTLC of cholesterol, triolein and phosphatidylcholine on silica gel by AMD with a gradient from chloroform - methanol - water 65:35:4 to diethylether - n-hexane 1:1 to n-hexane in 15 steps. Visualization by dipping in manganese(II) chloride reagent and heating at 110°C for 10 min. Quantification by densitometry at 366 nm/>400 nm. Recovery was found to be 99,4 %, repeatability and intermediate repeatability resulted adequate. Limit of detection (quantification) was 6,9 (21,2) ng for phosphatidylcholine, 2,6 (4,0) ng for cholesterol and 3,4 (8,7) ng for triolein.

CBS 85, 9 (2000). HPTLC of pot fragment extracts on RP-18 plates developed twice at 4 °C with first methanol - acetonitrile - THF 8:2:1 over 20 mm and second methanol - acetonitrile - THF 18:2:1 over 80 mm after pre-chromatographic derivatization with 1 % N,N’-dicyclohexylcarbodiimide in dichloromethane followed by dansyl semicadaverine in dichloromethane. After drying the plate was dipped in 4 % Triton X100 in hexane. Evaluation at 366/>400 nm.

J. AOAC Int. 91, 1218-1226 (2008). HPTLC of glycosphingolipids on silica gel with chloroform - methanol - water 60:35:8 or 65:25:4. Detection by spraying with orcinol reagent followed by heating at 110 °C. Detection with HPTLC/MS by direct coupling of HPTLC to matrix-assisted laser desorption/ionization quadrupole ion trap time-of-flight mass spectrometry showed to be a reliable and reproducible method to obtain structural information and fundamental properties of glycosphingolipids.

J. AOAC Int. 101, 1993-2000 (2018). HPTLC of neutral lipids in fatty acid methyl ester (FAME)-derived biodiesel (1) and sphingolipids in human plasma (2) on LiChrospher or silica gel with a 4-step gradient based on t-butyl methyl ether, dichloromethane, and n-heptane for (1) and a 7-step gradient based on methanol and dichloromethane for (2). Detection of neutral lipids by dipping into a methanolic primuline solution (0.02 g/100 mL), followed by fluorescence recording at 366/>400 nm. Detection of sphingolipids by absorbance measurement at 190 nm. Zones of interest were eluted into an electrospray ionization-ion trap MS (ESI-MS) using a TLC-MS interface. _x000D_
