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.
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.
J. Planar Chromatogr. 26, 153-159 (2013). TLC lipophilicities of 21 newly synthesized 1,2,4-triazoles on RP-8 and RP-18 with buffered solutions of acetone, 1,4-dioxane, tetrahydrofuran and acetonitrile as well as on cyano phase with solutions of 0.03, 0.04, 0.06, 0.08 and 0.1 M sodium dodecyl sulfate modified with the constant (20 %) addition of organic modifier (acetone, 1,4-dioxane, tetrahydrofuran and acetonitrile). Partitioning lipophilicity indices showed mobile phase composed of sodium dodecyl sulfate and tetrahydrofuran as the system providing the best linear correlations between chromatographic and partitioning lipophilicities of tested 1,2,4-triazoles.

J. AOAC Int. 98, 345-353 (2015). HPTLC of 14 derivatives containing the phenanthrene skeleton on RP, CN and NP phases. Quantitative structure-retention relationship analysis determined that the best conditions to predict log P was RP with acetone–water ranging from 30 to 80 % in 10 % increments of the organic modifier.
J. Planar Chromatogr. 30, 225-230 (2017). HPTLC of chlorpromazine, chlorprothixene, clozapine, quetiapine, perazine, perphenazine, prochlorperazine, promazine and trifluoperazine on silica gel (1) and amino phase (2) with tetrahydrofuran – petroleum ether ranging from 40 % to 100 % and methanol – petroleum ether ranging from 10 % to 50 % for (1) and a mixture of tetrahydrofuran – water ranging from 50 % to 100 % for (2). Detection by spraying with a mixture of concentrated sulfuric acid – methanol 1:4, followed by heating_x000D_
at 120 °C for 10 min. A statistical analysis was used for the development of the quantitative structure‒retention relationship (QSRR) model._x000D_
J. Planar Chromatogr. 31, 497-504 (2018). HPTLC of chloroacetamide derivatives on RP-18 with ethanol and tetrahydrofuran as organic modifiers with water. Lipophilicity was examined by cluster analysis and principal component analysis. The obtained chromatographic parameters of the examined acetamides were correlated with the standard measure of lipophilicity, log P.
