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_

CBS 114, 5-7 (2015). HPTLC of biodiesel (B100), biodiesel blended with diesel fuel in different proportions (BX, with X_x000D_ being the volume percent of B100 in the mixture) and standard monoacylglyceride on silica gel with the AMD 2 system in a 3-step development starting with 100 % t-butyl methyl ether (up to 40 mm), followed by dichloromethane – n-heptane 4:1 up to_x000D_ 60 mm and then 3:2 up to 90 mm as final migration distance. Detection by dipping in a 0.02 % methanolic solution of primuline. Quantitative determination of monoacylglycerides via the 1-oleyl glycerol standard by fluorescence measurement at 366/>400 nm. Elution of target zones with methanol, flow rate 0.2 mL/_x000D_min, via the TLC-MS Interface (oval elution head 4 x 2 mm) into an ion-trap MS operating in positive ESI mode. The final chromatogram showed a migration distance of 15-20 mm for the monoacylglyceride of BX, other lipids detected were diacylglycerides,_x000D_ triacylglycerides, fatty acids (20–60 mm) and fatty acid methyl esters (60–83 mm), the preponderant chemical class. The sample peak at 86 mm corresponded to the diesel component in the blend.
