      Analysis of glycosaminoglycan oligosaccharides by combined HPTLC/MALDI-TOF MS - reduced silica gel thickness leads to improved spectral qualities and reduced side reactions
      Katharina LEMNITZER, H. GRIESINGER, Rosmarie SUESS, Katerina MATHEIS, M. SCHULZ, J. SCHILLER* (*Institute of Medicinal Physics and Biophysics, Medical Faculty, University of Leipzig, Härtelstr. 16-18, 04107 Leipzig, Germany, juergen.schiller@medizin.uni-leipzig.de)

      Chromatographia 78, 1409-1413 (2015). HPTLC of oligosaccharides (derived from native chondroitin sulfate and hyaluronan) on silica gel aluminum foils of either "standard" or MS grade with 1-butanol - formic acid - water 3:4:1. Detection by staining with orcinol/sulfuric acid reagent or by MALDI-TOF MS. The hRf values of the unsaturated disaccharides of chondroitin sulfate (C4S, one sulfate residue per disaccharide unit) and chondroitin (C0S, no sulfate) were 43 and 55, respectively. The thickness of the silica gel layer (200 or 100 µm) influenced the quality of the mass spectra: a thinner layer improved the achievable signal-to-noise ratio and minimized unwanted formylation of the GAG oligosaccharides.

Detection under UV 254 nm and 366 nm. Densitometric evaluation by absorbance measurement at 254 nm. Elution of zones with TLC-MS Interface into a single mass spectrometer. Together with the already established sinensetin, scutellarein tetramethylether, eupatorin, and eupatorin-5-methylether were determined as specific markers suitable for the identification of Orthosiphon aristatus (Blume) Miq. by HPTLC. The presence of these four markers in the flavonoid profile is specific for Java tea.
