      Thin-layer chromatography and mass spectrometry coupled using desorption electrospray ionization
      M. J. FORD, M. A. DEIBEL, B. A. TOMKINS, G. J. VAN BERKEL* (*Org. and Biol. Mass Spectrometry Group, Chem. Science Division, Oak Ridge Nat. Lab., Oak Ridge, Tennessee 37831-6131)

      Anal. Chem. 77, 1207-1215 (2005). The use of desorption electrospray ionization for coupling TLC with MS was demonstrated for prewashed wettable unpolar C18, C8, and C2 and for polar silica gel phases. The experimental setup and its optimization are described as plate positioning was a crucial factor of influence on the MS signal. TLC of rhodamine dyes on RP-8 and RP-2 phases with methanol – water containing 200 mM ammonium acetate 4:1, MS analysis in the positive ion mode via SRM. TLC of FD&C dyes on wettable RP-18 phases with water – acetone 7:3 containing 500 mM ammonium acetate, MS analysis in the negative ion full scan mode. TLC of a mixture of aspirin, acetaminophen, and caffeine from a medicinal formulation on silica gel with ethyl acetate – acetic acid 99:1, MS analysis in the positive ion full scan mode. The capability of detection was in the µg-range on silica gel phases and not as good as on unpolar phases.

      Coupling Thin-Layer Chromatography with Vibrational Cooling Matrix-Assisted Laser Desorption/Ionization Fourier Transform Mass Spectrometry for the Analysis of Ganglioside Mixtures
      Vera IVLEVA, Y. ELKIN, B. BUDNIK, Susanne MOYER, P. O’CONNOR, Catherine COSTELLO* (*Mass Spectrometry Resource, Cardiovascular Proteomics Center, and Department of Biochemistry, Boston University, School of Medicine, 715 Albany Street R-806, Boston, Massachusetts 02118-2526, USA, cecmsms@bu.edu)

      Anal. Chem. 76, 6484-6491 (2004). TLC on silica gel with chloroform - methanol - 0.2 % calcium chloride 11:9:2 or chloroform - 2-propanol - 50 mM potassium chloride 10:67:23 for separation of glycolipids, oligosaccharides, lipids, and compounds of environmental and pharmaceutical interest with coupling to an external ion source MALDI-Fourier transform (FT) MS instrument without compromising mass accuracy and resolution of the spectra. Furthermore, when the FTMS, with >70 000 resolving power, has a vibrationally cooled MALDI ion source, fragile glycolipids can be desorbed from TLC plates without fragmentation, even to the point that desorption of intact molecules from “hot” matrixes such as a-cyano-4-hydroxycinnamic acid is possible. TLC of whole brain gangliosides derivatized with orcinol-sulfuric acid reagent. The positions of the fractions on a parallel developed plate were determined; the TLC plates were attached directly to the MALDI target using double-sided adhesive tape or the strip cut from TLC plate. Different matrices were tested.

      A TLC bioautographic method for the detection of alpha- and beta-glucosidase inhibitors in plant extracts
      C. SIMOES-PIRES, B. HMICHA, A. MARSTON, K. HOSTETTMANN* (*Laboratory of Pharmacognosy and Phytochemistry, University of Geneva, 1211 Geneva 4, Switzerland, kurt.hostettmann@unige.ch)

      Phytochem. Anal. 20, 511-515 (2009). Bioautography of alpha-D-glucosidase (1) and beta-D-glucosidase (2) in buffer solution (sodium acetate 4.1 % in water pH=7.5) sprayed onto a silica gel plate. Incubation at room temperature for 60 min for (1) and at 37 °C for 20 min for (2). For detection of the active enzyme, solutions of 2-naphthyl-alpha-D-glucopyranoside or 2-naphthyl-beta-D-glucopyranoside and Fast Blue salt were mixed at a ratio of 1:1 for (1) or 1:4 for (2), and sprayed onto the plate to give a purple background coloration after 2-5 min. Methanol extracts of the aerial parts of Tussilago farfara and Urtica dioica were tested as enzyme inhibitors and visualized as white spots on the TLC plates.

      High-performance thin-layer chromatography plate blotting for liquid microjunction surface sampling probe mass spectrometric analysis of analytes separated on a wettable phase plate
      M. WALWORTH, J. STANKOVICH, G. VAN BERKEL*, M. SCHULZ, S. MINARICK (*Organic and Biological Mass Spectrometry Group, Chemical Sciences Division, Oak Ridge National Laboratory, Oak Ridge, TN 37831-6131, USA, vanberkelgj@ornl.gov)

      Rapid Commun. Mass Spectrom. 26, 37-42 (2012). Blotting method to transfer analytes separated on wettable HPTLC plates to a hydrophobic RP-8 HPTLC plate. The hydrophobic RP-8 HPTLC plate was wetted with 500 mL methanol then left to evaporate until solvent saturation on the surface was no longer visible. Then the wet plate was placed over the hydrophilic HPTLC plate and pressure was applied to the plates for 10 min. The two plates were separated, and the dried RP-8 plate was analyzed using a liquid microjunction surface sampling probe in combination with electrospray ionization mass spectrometry (LMJ-SSP/ESI-MS). This method provides different means of expanding the utility of the LMJ-SSP approach into the analysis of wettable-phase HPTLC surfaces.

      Analysis of triterpenoids and phytosterols in vegetables by thin-layer chromatography coupled to tandem mass spectrometry
      Katerina NAUMOSKA, Irena VOVK* (*National Institute of Chemistry, Laboratory for Food Chemistry, Hajdrihova 19, 1001 Ljubljana, Slovenia, irena.vovk@ki.si)

      J. Chromatogr. A 1381, 229-238 (2015). TLC screening and TLC-MS2 analysis of triterpenoids and phytosterols on (A) RP-18 with ethyl acetate - acetonitrile 3:2; (B) RP-18 with with acetone - acetonitrile 5:1; (C) silica gel with n-hexane - ethyl acetate 5:1. Detection of (A), (B) and (C) by dipping with a methanolic solution of anisaldehyde reagent, followed by heating at 110 °C for 30 s. Qualitative identification under white light and at UV 366 nm. The TLC-MS Interface was used for the elution of compounds from the plates into a LCQ ion trap system equiped with atmospheric pressure chemical ionization in positive mode. Acetonitrile was used as an eluent at a flow rate of 0.3 mL/min. This approach of combination TLC and MS enabled positive assignment of different triterpenoids and phytosterols.
