      Characterization of Pterocarpus erinaceus kino extract and its gamma-secretase inhibitory properties
      S. HAGE, Serena STANGA, Claudia MARINANGELI, J.-N. OCTAVE, Ilse DEWACHTER, Joëlle QUETIN-LECLERCQ, P. KIENLEN-CAMPARD* (*Institute of Neuroscience, Université catholique de Louvain, 1200 Brussels, Belgium; pascal.kienlen-campard@uclouvain.be)

      Journal of Ethnopharmacology 163, 192-202 (2015). TLC of the aqueous extract (crude vs. after tannin removal on a polyamide column) of the kino (red hydrosoluble exudate) of Pterocarpus erinaceus on silica gel with s-butanol – water – acetic acid 14:5:5. Detection with vanillin-hydrochloric acid reagent revealed catechic tannins and related polyphenols as dark pink zones. These compounds showed hRfs between 0 and 40, and above 60 in the case of the crude extract, whereas they almost did not appear in the tannin-free fraction. The extracts were also submitted to HPLC-HRMS, allowing the identification of epicatechin monomer in both extracts and of oligomers in the crude extract only.

      Fractionation of coal tar pitch by planar chromatography for the characterization of large molecular mass materials
      A.A. HEROD*, R. KANDIYOTI, (Dept. of Chem. Eng. and Chem. Technol., Imperial Coll., Univ. of London, London SW7 2BY, UK)

      J. Planar Chromatogr. 9, 16-24 (1996). TLC of a coal tar pitch on silica with pyridine followed by N,N-dimethylformamide (I) and THF followed by toluene as solvent system after chamber saturation for 30 min; first development 2 - 3 cm, after removal and drying development in the second solvent for a further 2 - 3 cm beyond the first solvent front. Separated sample fractions were examined by size exclusion chromatography, UV-absorbance, and UV-fluorescence spectroscopy.

      Separation of pigment formulations by high-performance thin-layer chromatography with automated multiple development
      Constanze STIEFEL, Sylvia DIETZEL, M. ENDRESS, Gertrud E. MORLOCK* (*Justus Liebig Univ. Giessen, Chair of Food Sci., Inst. of Nutritional Sci., and Interdisciplinary Res. Center (IFZ), Heinrich-Buff-Ring 26-32, 35392 Giessen, Germany)

      J. Chromatogr. A 1462, 134-145 (2016). Development of simple method for the separation of different colored pigment formulations used in the printing materials on food packaging to control the quality and safety of the package. HPTLC on silica gel by automated multiple development with a 9-step gradient based on ethyl acetate, methanol and water, and ending with toluene. Good resolution of differently soluble constituents of the pigment formulation like additives and coating materials. The results obtained by multi-detection allowed a first assignment of the differently detectable bands to particular chemical substance classes, enabled the comparison of different commercially available pigment batches and revealed substantial variations in the composition of the batches. Characterization of single unknown pigment constituents by HPTLC-MS and HPTLC combined with ATR-FTIR. The new HPTLC method for routine quality control for incoming pigment batches and monitoring of internal pigment production processes secures a consistent pigment composition, resulting in consistent ink quality. Hyphenation of HPTLC with the Aliivibrio fischeri bioassay revealed information on the toxicological potential of different pigment compounds which helps guarantee consumer safety, especially in regard to readily permeable pigment components.

      Planar chromatography as a method of fractionation of a coal liquefaction extract for Mössbauer spectroscopy

      J. Planar Chromatogr. 9, 363-367 (1996). Semipreparative TLC of coal liquefaction extracts on silica with pyridine (for 42 mm) and acetonitrile (for 77 mm) as mobile phases. Separation into (1) material immobile in both solvents; (2) material mobile in the first solvent but not in the second; and (3) material mobile in both solvents.

      Preliminary results for interval feeding the orthogonal pressurized planar electrochromatography system with sample solution for its preparative separation
      R. GAJOS, A. CHOMICKI, B. POLAK, T. H. DZIDO* (*Dep. of Phys. Chem., Chair of Chem., Med. Univ., Lublin, Poland, rafal.gajos@umlub.pl)

      J. Chromatogr. A 1499, 183-189 (2017). Description of the 2-D separation technique orthogonal pressurized planar electrochromatography (OPPEC), in which two simultaneous and orthogonal processes of electrophoresis and chromatography are involved in the separation mechanism. In the case of preparative separation of substances characterized by different electrophoretic mobility, such a separation system can be constantly fed with the sample solution and the separated components can be constantly collected at its outlet. Discussion of the capabilities of OPPEC for preparative separation of substances characterized by the same electrophoretic mobility. In the proposed solution, the separation system is periodically fed with the sample solution and separated components are collected alternately at its outlet. The new approach might be advantageous to column chromatography with regard to the separation of complex mixtures.
