      The characterization of dyes in textiles from archaeological excavations
      P. WALTON, G.W. TAYLOR

      Chromatography and Analysis 5-7 (1991). TLC of dye-stuffs from textile fragments found at UK archaeological sites. Comparison with HPLC. HPLC is regarded as useful for further investigations, TLC is better as a rapid screening procedure at low cost.

      Application of a mixed adsorbent for flow TLC
      A.M. WORONTSOV, A.B. MARKOV, V.G. BEREZKIN*, (*A.V. Topchiev Inst. of Petrochemical Synthesis, Russian Acad. of Sci., 29 Lenin av., Moscow 117912, Russia)

      J. Planar Chromatogr. 14, 208-210 (2001). Separation of dyes, polycyclic hydrocarbons (phenanthrene, benzopyrene, anthracene, fluoranthene, pyrene, triphenylene, azulene, naphthacene, chrysene, perylene) and a vegetable chlorophyll extract on plates prepared from Piresorb A, silica gel, luminophore and liquid glass as binder with benzene, hexane, benzene - hexane 14 and ethyl acetate - acetonitrile 37. For flow TLC it is necessary to use TLC plates with sorbents different from those used in classical TLC.

      Validation of NP-HPTLC and RP-HPTLC methods with videodensitometric detection for analysis of ziprasidone in pharmaceutical formulations
      R. SKIBINSKI*, L. KOMSTA (*Department of Medicinal Chemistry, Medical University of Lublin, Jaczewskiego 4, 20-090 Lublin, Poland, robert.skibinski@am.lublin.pl)

      J. Planar Chromatogr. 23, 23-27 (2010). HPTLC of ziprasidone (5-[2-[4-(1,2-benzothiazol-3-yl)piperazin-1-yl]ethyl]-6-chloro-1,3-dihydroindol-2-one) on silica gel with hexane - dioxane - propylamine 5452 up to 9 cm (under saturated conditions) and on RP8 with tetrahydrofuran - phosphate buffer (pH 9.0) 11 up to 4.5 cm (under unsaturated conditions), both in horizontal chambers. Quantitative determination by videodensitometry at 254 nm. Calibration was linear in the range 0.2-1.2 and 0.1-1.1 µg/spot ziprasidone for NP-HPTLC and RP-HPTLC, respectively. The intra-day precisions for 0.4-1.2 µg/spot on NP-HPTLC was 2.0 to 5.2 % and on RP-HPTLC 4.0 to 6.1 %; the respective inter-day precision for NP-HPTLC was 2.0 to 6.7 % and for RP-HPTLC 4.1 to 7.1 %. LOD/LOQ on NP-HPTLC was 0.03/0.09 µg/spot; using RP-HPTLC, LOD/LOQ was 0.02/0.06 µg/spot. The specificity of the methods was confirmed by comparison of hRf values (74 +/- 2 in NP-HPTLC and 36 +/- 1 in RP-HPTLC, n=12).

      J. Braz. Chem. Soc. 27, 1067-1077 (2016). HPTLC for the kinetic study involving the conversion of 2,3-dichloro-6,7-dinitroquinoxaline (1) into 2-chloro-6,7-dinitro-3-pyrrolidinoquinoxaline (2) and then into 6,7-dinitro-2,3-dipyrrolidinoquinoxaline (3) on silica gel through monosubstitution of a chlorine group with one equivalent of pyrrolidine. First, for obtaining calibration sets, 1 ?L of solutions containing compounds (2) and (3) in chloroform with concentrations ranging from 1.0 to 8.0 mM were applied separately on chromatographic plates. In the kinetic study, 100 ?L of a solution of compound (1) in chloroform (0.32 M) was added to 100 ?L of pyrrolidine in chloroform (1 M eq). 10 ?L of the reaction media taken at different times (30, 60, 90, 120, 180, 240, 300, 600, 1200 and 1800 s) was applied onto the TLC layer and separated with chloroform. All the final chromatograms were directly scanned to generate their digital image. Detection by absorbance measurement at 411 nm for (2) and 331 nm for (3). Kinetics profile was constructed for reagent (2) consumption and product (3) formation.
