      J. Liq. Chromatogr. Relat. Technol. 30, 2891-2902 (2007). HPTLC of L-glutamate and L-aspartate on silica gel by double elution with n-butanol - acetic acid - water 13:3:5 in a chamber saturated for 3 h. Detection by spraying with 0.2 % ninhydrin solution in acetone. Quantitative determination by absorbance measurement at 486 nm.

      Two-dimensional separation of some amino acids by HPTLC and pressurized planar electrochromatography
      A. CHOMICKI, K. KLOC, T. H. DZIDO* (*Department of Physical Chemistry, Medical University of Lublin, Chozki 4a, 20-093 Lublin, Poland; tadeusz.dzido@umlub.pl)

      J. Planar Chromatogr. 24, 6-9 (2011). Two-dimensional separation of eight amino acids (arginine, phenylalanine, histidine, glutamic acid, leucine, lysine, threonin, and tryptophan) by HPTLC in the first dimension and pressurized planar electrochromatography in the second, orthogonal direction. HPTLC on RP-18, prewashed by dipping into methanol for 1 min, with acetonitrile - buffer solution. Buffer solutions of pH 3.2-7.0 were prepared by mixing 0.1 M citric acid with 0.2 M disodium hydrogen phosphate. Chromatogram development was performed with 10 % acetonitrile in buffer (pH 3.2) in a horizontal chamber after saturation for 15 min. Then the HPTLC plate was prewetted with mobile phase, inserted into the PPEC chamber and separation was performed for 21 min at a polarization voltage of 2.5 kV. Detection by spraying with ninhydrin reagent followed by heating under a hot air stream. Combination of HPTLC and PPEC in a two-dimensional process leads to substantial enhancement of amino acid separation.

      Thin-layer chromatographic investigation of L-cysteine in solution
      Agnieszka GODZIEK, Anna MACIEJOWSKA, Ewa TALIK, M. SAJEWICZ, Teresa KOWALSKA* (*Institute of Chemistry, University of Silesia, 9 Szklona Street, 40-006 Katowice, Poland, teresa.kowalska@us.edu.pl)

      J. Planar Chromatogr. 28, 144-151 (2015). TLC of L-cysteine on cellulose phase with 2-butanol - pyridine - glacial acetic acid - water 5:10:3:12. Just before development an equimolar amount of (1) manganese(II) acetate or (2) zinc(II) nitrate was added to the sample solutions. Detection in reflectance mode at 485 nm, concentration of L-cysteine and DL-cysteine in 70 % aqueous acetonitrile was 0.7 mg/mL. Developing distance was 7 cm, development time ca. 3 h. Derivatization by spraying with 0.5 % ninhydrin solution in 2-propanol, followed by heating for 5 min at 110 °C. The experiments demonstrate the spontaneous chiral conversion and spontaneous peptidization of L-cysteine, and the enantioseparation of L-cys and D-cys enantiomers is facilitated by chelating the transition metal cation (e.g. Mn(II)) with the cys ligands.
