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_

TLC of lipid extracts on silica with various solvent systems. Detection by spraying with different reagents. Quantification by densitometry at 550 nm and 650 nm. Determination of sialic acid by HPLC.

Anal. Chem. 75, 118-125 (2003). Online TLC separation and electrospray mass spectrometry (TLC/ESI-MS) by direct linking of a commercial overpressure TLC instrument, OPLC 50, and a Q-TOF mass spectrometer. Separation on silica gel with dichlormethane - methanol - water 60:35:8. A sensitivity of 5 pmol of glycosphingolipid was readily demonstrated for TLC/ESI-MS and 20 pmol for TLC/ESI-MS/MS production scanning to derive the saccharide sequence and long chain base/fatty acid composition of the ceramide. Initial preconditioning of TLC plates is necessary to achieve high sensitivity detection by reducing chemical background noise. Plates can be used repeatedly (at least 10 times) for analysis, although this may result in a minor reduction in TLC resolution. Following solvent development, separated components on the TLC plates can be detected in the conventional way by nondestructive staining or UV absorption or fluorescence and can be stored for on-line TLC/ESI-MS analysis at a later stage without reduction in mass spectrometric detection sensitivity and chromatographic resolution. Aspects for further improvement of OPLC instrumentation include use of narrower TLC plate dimensions and refined design of the eluate exit system.
J. Chromatogr. A 1572, 137-144 (2018). Development of a method for the analysis of anthocyanes within the foodstuffs of plant origin by TLC on RP-18 phase (which ensures mixed-mode retention mechanism with the localized adsorption on the non-bonded silanols) with acetic acid as the mobile phase component, using two anthocyanins (cyanin and keracyanin) and two anthocyanidins (pelargonidin and delphinidin) as phytochemical standards. By triple development, distinct and symmetrically shaped chromatographic zones were obtained. Further analysis of the products of hydrolytic degradation of the test anthocyanins by MS. Identification of the hydrolytically split fractions by using the p-aminobenzoic acid reagent. Investigation of the calibration curves for cyanin, keracyanin, pelargonidin and delphinidin, and the respective LOD and LOQ values. Application of the method to identify and quantify cyanin, keracyanin, pelargonidin and delphinidin in selected alimentary products (syrups, juices and herbal infusions).
J. Chromatogr. A 720, 3-25 (1996). A review with 234 references on the current improvement of TLC of gangliosides over the past decade, including basic general techniques and advice for separation of glycosphingolipids, new approaches concerning continuos and multiple development and preparative TLC and related techniques in practical applications.
Anal. Chem. 77, 4098-4107 (2005). Novel method for direct coupling of HPTLC with matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) for the analysis of biomolecules. HPTLC of gangliosides on silica gel with chloroform - methanol - water 24:17:4 containing 2 mM calcium chloride, with chamber saturation for 20 min. Detection by dipping for 10 s in 0.3 % (w/v) orcinol in 3 M sulfuric acid, followed by heating at 110 °C. Use of a glycerol as matrix, which provides a homogeneous wetting of the silica gel and a simple and fast preparation protocol. Use of an Er:YAG infrared laser, which ablates layers of 10 µm thickness of analyte-loaded silica gel and provides a soft desorption/ionization of even very labile analyte molecules. The orthogonal time-of-flight mass spectrometer employed in this study, finally provides a high accuracy of the mass determination, which is independent of any irregularity of the silica gel surface. The method is demonstrated by the compositional mapping of a native GM3 (II3-r- Neu5Ac-LacCer) ganglioside mixture from cultured Chinese hamster ovary cells. The analysis is characterized by a high relative sensitivity, allowing the simultaneous detection of various major and minor GM3 species directly from analyte bands. The lateral resolution of the direct HPTLC-MALDI-MS analysis is defined by the laser focus diameter of currently 200 µm. This allows one to determine mobility profiles of individual species with a higher resolution than by reading off the chromatogram by optical absorption.
