      TLC separation of rare earths using di(2-ethylhexyl)dithiophosphoric acid as complexing agent
      Maria-Loredana Soran*, T. Hodisan, M. Curtui, D. Casoni (*National Institute of Research and Development for Isotopic and Moleculer Technology, 72-103 Donath Street, 400293 Cluj-Napoca, Romania)

      J. Planar Chromatogr. 18, 160-163 (2005). TLC of rare earths (La(III), Ce(III), Pr(III), Sm(III), Gd(III), Er(III)) on silica gel and silica gel impregnated with 2.5 M ammonium nitrate with different mixed mobile phases containing di(2-ethylhexyl)dithiophosphoric acid as a complexing agent. The best results were obtained by use of ethyl methyl ketone - tetrahydrofuran - 1 M di(2-ethylhexyl)dithiophosphoric acid 17:8:1. Double development was used to obtain better separation of consecutive rare earths.

      Comparison of on-line injection and off-line sample application as well as on-line and off-line detection using continuous development HPTLC
      K. DEAK, SZ. NYIREDY*, (*Res. Inst. for Med. Plants, Lupaszigeti ·t 4, 2011 Budakalasz, Hungary)

      Proc. Intern. Symp. on Planar Separations Plan. Chrom. 211-221 (2003). Description of the applications of continuous development HPTLC techniques combining on-line and off-line chromatographic principle steps (sample application, separation and detection). Fully on-line combination of off-line sample application and on-line detection as well as fully off-line methods are compared by separating Test Dye Mixture III and furocoumarin isomers. HPTLC of Test Dye Mixture III on silica gel with toluene and different compositions of toluene and chloroform mixtures 9:1, 15:3, 4:1 and HPTLC of furocoumarin isomers on silica gel with ether - dichloromethane - tetrahydrofuran - hexane 10.71:9.68:7.5:72.11, diluted with 50%, 75%, and 100% hexane. All experiments were performed in a further developed prototype apparatus. Detection by densitometry in a range of 200 -1000 nm.

      Post TLC developing technique for tyrosinase inhibitor detection
      S. WANGTHONG*, I. TONSIRIPAKDEE, T. MONHAPHOL, R. NONTHABENJAWAN, S. PATTANAARGSON WANICHWECHARUNGRUANG (*Department of Chemistry, Faculty of Science, Chulalongkorn University, Payatai, Bangkok 10330, Thailand)

      Bio. Chromatogr. 21(1), 94-100 (2008). The method for detection of tyrosinase inhibiting substances involves spraying of the TLC layer with tyrosinase and l-tyrosine solutions successively. Positive results are detected as white spots against a brownish-purple background. The method is suitable either as a quick screening method for tyrosinase inhibitor detection or as a guiding procedure for an isolation of tyrosinase inhibitors from mixtures or natural product extracts. The technique is sensitive enough for results in the presence of 6 ng/zone glabridin.

      J. Planar Chromatogr. 27, 340-345 (2014). TLC and HPTLC studies on the influence of application of external magnetic field during chromatogram development for the separation of multicomponent mixtures of flavonoids and phenolic compounds in plant extracts of Hypericum perforatum L., Salvia officinalis L., Matricaria chamomilla L., Thymus vulgaris L. and Achillea millefolium L. The inductivity of the field used in the experiment was about 0.44 T. The method had the potential to modify peak number, retention and width of the peaks.

      natural polymers and planar chromatographic stationary phases

      J. Planar Chromatogr. 30, 440-452 (2017). For electroseparation experiments in a commercially available, open-air electrophoresis box, thirteen types of separation layers (filtrating paper, office paper, chromatography paper, Japanese paper for aircraft paper models, potato starch on cellulose support, common HPTLC glass plates coated with cellulose, silica gel, RP-18W, and aluminum oxide as well as glass-based nutrient agar layers) were investigated. The best separation was observed for the cellulose pre-coated TLC layer and the starch layer on filtrating paper support. The study revealed substantial differences between the electrophoretic migration of target dyes within cellulose type layers and also in comparison to the remaining stationary phases studied. Combined planar electrophoresis–electrochromatography of methyl red and ponceau R colorants on active thin-layers composed of starch powder on cellulose strips and agar layer on glass-based support connected with electrolyte containers. The resulting dye pattern on active layers was acquired using an office scanner.
