      The use of topological indexes to predict the RM values of higher fatty acids, hydroxy fatty acids and their esters in RPTLC
      A. NIESTROJ, A. PYKA, J. SLIWIOK*, (*Silesian Univ., Inst. of Chem., 9 Szkolna Street, PL-40-006 Katowice, Poland)

      J. Planar Chromatogr. 15, 177-182 (2002). HPTLC of 12 fatty acids, hydroxy fatty acids and methyl esters (oleic acid, elaidic acid, palmitic acid, stearic acid, ricinoleic acid, methyl ricinoleate, a-hydroxypalmitic acid, methyl a-hydroxypalmitate, 12-hydroxystearic acid, methyl 12-hydroxystearate, 9,10-dihydroxystearic acid, methyl 9,10-dihydroxystearate) on RP-18 with methanol and methanol - water 19:1 and 9:1. previously saturated for 30 min. Visualization by exposure to iodine vapor. The most accurate prediction of the RM values of the acids and esters, for all the mobile phases investigated, was achieved by use of four-parameter equations relating the dipole moments of the mobile phases to three other parameters.

      J. Liq. Chromatogr. Relat. Technol. 28, 907-922 (2005). HPTLC of eight pairs of ortho and para substituted phenols and anilines on amino, diol, and cyano phase, with chamber saturation for 15 min, with nonaqueous eluents consisting of n-heptane and polar modifier (tetrahydrofuran, ethyl acetate, or 2-propanol), or on cyano phase in RP systems with aqueous solutions of methanol or acetonitrile. Evaluation under UV 254 nm.

      Application of RP-18 thin-layer chromatography
      and quantitative structure–activity relationship analysis for the prediction of the blood–brain barrier permeation

      University of Lodz, 1, Muszy?skiego Str., 90-151 Lodz, Poland, anna.sobanska@umed.lodz.pl)

      J. Planar Chromatogr. 29, 287-298 (2016). HPTLC of 34 structurally diverse drugs on RP-18 with acetonitrile – pH 7.4 phosphate buffered saline 7:3. Detection under UV 254 nm. Molecular descriptors were investigated to assign the compounds to two clusters: central nervous system active (CNS+) or inactive (CNS-) describing the ability of the compounds to penetrate the brain.

      Computer-aided optimization of liquid-solid systems in TLC - 2) Comparison of selectivity for various silica-diluent + modifier systems
      M. MATYSKA*, E. SOCZEWINSKI, (*Dept. of Inorg. & Anal. Chem., Medical Acad., ul. Staszica 5, 20-081 Lublin, Poland)

      J. Planar Chromatogr. 3, 264-268 (1990). Comparison of various diluent + modifier - silica systems for 57 solutes by graphical methods; i.e. RM vs. eluent spectra plotted on the basis of equieluotropic series of RM1 vs. RM2 correlations. The spread of points was largest when the binary eluents differed in both diluent and modifier. The differentiated selectivity characteristics of the diluent - modifier binaries demonstrate good prospects for computer-aided selection of an optimal system for TLC analysis of a given set of compounds from the data base.

      A study of the solvolytic cleavage of octadecyl ligands from the surface of RP-18 stationary phases in TLC
      T. KOWALSKA*, A. PODGORNY, (Inst. of Chem., Silesian Univ., 9 Szkolna Street, 40 006 Katowice, Poland)

      Part 1. J. Planar Chromatogr. 9, 430-434 (1996). Investigation of the stability of RP-18 TLC stationary phases, specifically their resistance to cleavage of the chemical bonds coupling the octadecyl ligands to the silica matrix using methanol - phosphate buffer (pH 3) solutions, repeatedly passed through the layer. It was demonstrated that cleavage of about fifty percent of octadecyl ligands from the matrix occurs in the course of the initial two runs of the methanol - phosphate buffer solutions through the RP-18 layer, and after this the stationary phase remains stable.
