      J. Liq. Chromatogr. Relat. Technol. 42, 563-569 (2019). TLC of 17 new anti-proliferative and antiinflammatory tetracyclic 6-substituted 9-fluoroquinobenzothiazines on RP-18 with acetone - aqueous TRIS (tris(hydroxymethyl)-aminomethane) buffer pH 7.4 (ionic strength 0.2 M), where the concentration of acetone was from 50 to 85 % in 5 % increments. Lipophilicity parameters were determined (RM0 and logPTLC) and compared with computationally calculated lipophilic parameters. Relation of lipophilicity with predicted and experimental biological activities was discussed.

      Differences in the efficiency of separation of analgesic drugs by high-performance thin-layer chromatography with similar octadecyl silica-based adsorbents
      M. TRZEBIATOWSKI*, R. GWARDA, T. DZIDO (*Department of Physical Chemistry, Medical University of Lublin, Chodźki Str. 4A, 20-093 Lublin, Poland, michal-trzebiatowski@wp.pl)

      J. Planar Chromatogr. 32, 517-520 (2019). HPTLC of tramadol (1), caffeine (2), paracetamol (3), ibuprofen (4), naproxen (5), and diclofenac (6) on RP-18 WF, LiChrospher RP-18 WF, and RP-18 WF with concentration zone, developed with various ratios of methanol in water with 0.1 M potassium chloride. Qualitative identification under UV light at 254 nm. Potassium chloride may be used to suppress ion–ion interactions between the solutes and the silica gel surface.  HPTLC RP-18WF plates with concentration zone and developed with methanol - water 13:7 with addition of 0.15 mol/L KCl were suitable for the qualitative and quantitative analyses of tramadol, paracetamol, caffeine, naproxen, and ibuprofen or diclofenac. The method allowed to study subtle differences in the efficiency of the separation of analgesic drugs by HPTLC with similar octadecyl silica-based adsorbents.

      J. Planar Chromatogr. 32, 265-271 (2019). HPTLC of 24 anions on tri-n-butyl amine (TBA) impregnated silica gel with 13 mobile phases (methanol, dimethylformamide, diisopropyl ether, tetrahydrofuran, 2-propanol, dimethylformamide - methanol 1:1, dimethylformamide - diisopropyl ether 1:1, dimethylformamide - tetrahydrofuran, 1:1, dimethylformamide - 2-propanol 1:1, 0.1 M oxalic acid, 0.1 M tartaric acid, 0.1 M citric acid and 0.1 M succinic acid). The retention behavior was analyzed in aqueous and non-aqueous mobile phases. The hRF values were also correlated with their lyotropic numbers. 20 % TBA-impregnated silica gel was found very effective for binary and ternary separations of anions.

      J. Planar Chromatogr. 20, 251-257 (2007). TLC with aqueous ammonia-organic modifier (acetonitrile, dioxane, acetone) mobile phases has been used to study the effect on retention of the chromatographic system and the physicochemical properties of twelve 2,4-dioxotetrahydro-1,3-thiazoles. Principal-component analysis and partial least-squares regression were used to determine the molecular properties with the greatest effect on retention for each modifier. Good correlation was obtained between experimental and calculated retention data. HPTLC on RP-18 without chamber saturation. Detection under UV 254 nm.
