Chin. J. Chem. 18, 872-876 (2000). HPTLC of 19 N-(benzothiazol-2-yl)-a-amino alkyl phosphonic diesters on RP-18 with methanol-water mixtures, the concentration of methanol ranging from 75% to 90% in steps of 5%. Detection under UV. The correlation of the chromatographic parameters k' and Rf with the lipophilicity parameter (Clog P) was established. Rapid and simple method; alternative for lipophilicity measurement.

Part II. TLC of some phenols. J. Planar Chromatogr. 17, 9-13 (2004). TLC separation of some phenolic compounds (phloroglucinol, 2-aminophenol, 4-hydroxybenzaldehyde, 4-methoxyphenol, salicylic acid, phenol, 4-tert-butylphenol, 2,4-dichlorophenol, 2,6-dimethylphenol) on CN-phases, silica gel and polyacrylonitrile with 14 different mobile phases at ambient temperature in a HPTLC horizontal developing chamber. Detection by spraying with 0.05 % fluorescein solution in ethanol and subsequent exposure to UV light at 366 nm.

J. Planar Chromatogr. 18, 240-243 (2005). TLC of twenty-one N-benzyl-2-azaspiro[4.4]nonane- and [4.5]decane-1,3-dione derivatives on RP-18 with a mixture of n-propanol and TRIS buffer (pH 7.0) in a chamber saturated for 30 min. Detection under UV light at 254 nm. Examination of chromatographic behavior revealed a linear correlation between RM values and the concentraton of n-propanol in the mobile phase.

J. Liq. Chromatogr. Relat. Technol. 35, 1314-1324 (2012). HPTLC of 16 alkoxy-phenylbenzamide derivatives on silica gel pre-coated overnight with n-hexane - paraffin oil 19:1, with a mixture of organic solvent - water. The ratio of the organic solvent component (n-hexane, acetone, ethyl alcohol, methyl alcohol, and dioxane) changed in steps of 5 vol %. Quantitative determination by absorbance measurement under UV light (no wavelength given). Lipophilicity parameters (lipophilicity, extrapolated to zero concentration of organic modifier; specific hydrophobic surface area) were calculated from the retention data.

The effect of support and the organic phase in the eluent. Chromatographia 25, 908-914 (1988). Determination of the lipophilicity of some photosynthetic pigments by reversed-phase TLC on silica, alumina, cellulose, polyamide and diatomaceous earth with water - acetone and water - ethanol. Investigation of the effect of support and the organic phase in the eluent.

J. Planar Chromatogr. 3, 430-431 (1990). TLC of 4 dithia[3.3]-phanes on RP-18 silica with methanol - water 9:1. Visualization under UV. Numerical values of the Rf coefficient were established for each solute-phase combination, regressionally fitted into a physically based equation resulting in good correlation.

The effect of pH. J. Liquid Chromatogr. 16, 1805-1817 (1993). Determination of the lipophilicity of 17 monoamine oxidase inhibitory drugs by reverse-phase TLC on paraffin-impregnated silica with water - methanol systems containing acetic acid, sodium acetate and sodium chloride. Study of the effect of various eluent additives on the retention.

J. Planar Chromatogr. 9, 25-30 (1996). Investigation of the mechanism of solute retention in adsorption TLC on alumina with three different mobile phases, isopropanol - hexane, n-butanol - hexane, and t-butanol - hexane as well as interpretation in terms of the types of active site available on the alumina surface and the possible intermolecular interactions between the solute molecules and the sites. Also comparison of the results obtained on alumina with analogous results previously reported for silica as stationary phase.
