Chromatographia 41, 167-174 (1995). Study of the possible relation existing between Rf values obtained for a group of anilines with connectivity indices. Investigation of the corresponding connectivity functions, selected deviations, Snedocor's F and Student's t by using multivariable regression. Discussion of the prediction of the experimental elution sequence for this group of substances on silica layers with various mobile phases of different polarity.

Anal. Chim. Acta 316, 105-110 (1995). Study of the interaction of 23 antisense nucleosides with amino acids by charge-transfer reversed-phase TLC, and evaluation of the retention matrix by principal component analysis. Discussion of the effect of amino acids on the retention of nucleosides, and stacking interactions between the ring structures of nucleosides and Trp and Phe.

J. Planar Chromatogr. 10, 457-457 (1997). TLC of six pairs of facial-meridional isomers of Co(III) complexes of the type uns-cis[Co(eddp)Am] on silica with 18 different mobile phases (six monocomponent and twelve polycomponent). When monocomponent mobile phases were used, the meridional isomers always had higher RF values than the corresponding facial isomers.

J. Planar Chromatogr. 12, 175-179 (1999). Description of a retention model describing quantitatively the contribution of two complementary processes occurring in parallel during the course of solute migration through the stationary phase bed; the intermolecular interactions of a solute with the chemically bonded organic ligands and the intermolecular interactions of a solute with the free silanols on the surface of the silica matrix. The overall mechanism of solute retention was ultimately given as a sum of the two contributions.

Chinese J. Chromatogr. (Sepu) 18 (3), 206-211 (2000). Determination of the TLC retention on silica with chloroform - ethyl acetate - methanol - water 15:40:22:10. Calculation of 17 structure parameters of the 10 ginsenosides, including topologic indices and physicochemical properties. A novel parameter "E" was presented based on the differences of the parent substances of which the ginsenosides are composed. Three parameters (Aw, oB and E) were selected by optimization and used in the derived multi-parameter regression equation. Discussion of the relationship between the retention and the molecular structures (QSRR).

J. Planar Chromatogr. 15, 263-267 (2002). HPTLC of 24 Co(III), Cr(III), and Ru(III) complexes of the types [M(acac)3-n(phacphac)n]and [M(acac)3-n(phacphSac)n] with 18 different one- or two-component non-aqueous mobile phases. After development the colored spots were readily visible. The dependence of retention data on the length of ionic radius is discussed.

J. Planar Chromatogr. 18, 358-363 (2005). TLC of ten 1-arylpiperazines and five so-called ,standards’ (e.g. thiourea, anthracene, o-phenylenediamine) on RP-18 W in a horizontal chamber with 80-100 % methanol in water in steps of 5 % and 60-80 % dioxane in water in steps of 5 %. Detection under UV light at 254 nm.

J. Liq. Chromatogr. Relat. Technol. 35, 1289-1297 (2012). TLC of fourteen geometrically isomeric Co(III) complexes: three pairs of neutral fac-mer isomers, one pair of cis-trans isomeric complexes of neutral type and three pairs of cationic cis-trans isomers, on silica gel with mobile phases consisting of different ratios of water, methanol and sodium chloride. The retention behavior of the Co(III) complexes was investigated, revealing that the most selective systems were chromatographic systems with low content of water. A significant effect of sodium chloride on the retention was observed.
