      Use of water-in-oil microemulsion as mobile phase in complexation TLC of amino acids on silica layers impregnated with metal cations
      A. MOHAMMAD*, V. AGRAWAL, S. KUMAR, (*Dept. of Appl. Chem., Fac. of Eng. and Techn., Aligarh Muslim Univ., Aligarh 202002, India)

      J. Planar Chromatogr. 16, 220-226 (2003). TLC of 24 amino acids (i.a. glycine, L-hydroxyproline, DL-alanine, DL-serine, L-proline, L-tyrosine, DL-valine, L-leucine, DL-iso-leucine, DL-nor-leucine, L-lysine monohydrochloride) on silica gel impregnated with micellar copper sulfate solution as stationary phase and a water-in-oil microemulsion as mobile phase. This system has been proposed for selective separation of DL-phenylalanine from other amino acids.

      Two new methods for early detection of the effects of herbicides in plants using biomarkers
      H.W. RAVN (Aarhus University, National Environmental Research Institute, Department of Terrestrial Ecology, PhytoChemLab, Vejlsoevej 25, P. O. Box 314, 8600 Silkeborg, Denmark, her@dmu.dk)

      J. Planar Chromatogr. 22, 65-71 (2009). Presentation of two simple and rapid HPTLC methods for early detection of the effects of herbicides using two different groups of plant biomarkers, which were developed as field tests (Herbicide Weed Response test - HWR-Test). Phytochemical changes can be detected before any morphological changes are visible on the plants. These changes are defined as biomarkers and can be detected by HPTLC-screening. After overall identification of the phytochemical biomarker pattern, two different biomarker groups, carbohydrates and amino acids, were detected using modified reagents for color reactions. Evaluation under daylight and videodensitometric analysis of digital images by VideoScan software. The screening method was previously described [H. W. Ravn, M. Hjorth, L. Lauridsen, P. Kudsk, S. K. Mathiassen, L. Mondolot, Bull. Environ. Contam. Toxicol. 75, 236-245 (2005)].

      Separation of amino acid 2,4-dinitrophenyl-5-L-valine amide diastereomeric derivatives with high-performance planar chromatography and pressurized planar electrochromatography
      B. POLAK*, K. BALASA, T. DZIDO (*Department of Physical Chemistry, Medical University of Lublin, Chodyki 4A, 20-093 Lublin, Poland, beata.polak@umlub.pl)

      J. Planar Chromatogr. 26, 180-189 (2013). HPTLC of 2,4-dinitrophenyl-5-L-valine amide derivatives of some amino acids (leucine, isoleucine, valine, asparagine, cysteine, tryptophane) L and D-enantiomers on RP-18 with aqueous buffer pH 2.2 (1.47 mM citric acid, 0.06 mM disodium hydrogen phosphate) and acetonitrile 50 %. The statistic evaluation of the migration distance compared with pressurized planar electrochromatography (PPEC) shows similar RSD.

      Anticonvulsant activity and acute neurotoxic profile of Achyranthes aspera Linn
      D. GAWANDE, D. DRUZHILOVSKY, R. GUPTA, V. POROIKOV, R. KUMAR (*Department of Pharmaceutical Sciences and Drug Research, Punjabi University, Patiala 147002, Punjab, India, goelrkpup@gmail.com)

      J. Ethnopharmacol. 202, 97-102 (2017). HPTLC of betaine in the roots of Achyranthes aspera on silica gel with methanol – water 9:1. Detection by spraying with Dragendorff's reagent, followed by 10 % ethanolic sulfuric acid and drying at 110 °C for 5 min. Quantitative determination by densitometry at 520 nm. The hRF value for betaine was 36. Linearity was between 1 and 5 μg/band. The intermediate precision was below 2 % (n=6). LOD and LOQ were 0.13 μg/mL and 0.10 μg/mL, respectively. (Note: The reported LOD and LOQ do not make sense, as LOD is higher than LOQ.)

      J. Chromatogr. 355, 354-357 (1986). Enantiomeric HPTLC separation of racemic mixtures of amino acids on RP-18 plates impregnated with copper(III)complexes of chiral ligands of the type AA-NN-n. In these ligands two L-amino acids are joined via an amide bond by ethylene and trimethylene bridges. As solvents, mixtures of acetonitrile - water at different pH are used. Also two-dimensional HPTLC of Dans-amino acids with 1) water - acetonitrile 7:3 and 2) water -acetonitrile 58:42, pH 7.5, after treatment with the Cu(II)-Phe-NN-2 complex (4 mM).
