Abstract
α-, β-, γ- and δ-tocopherols have been separated by reversed phase thin layer chromatography using seven different mobile phases. The RM values of the compounds have been correlated with the numerical values of the topological indexes, the sum of the net electron charge ΣNEC) on the tocopherols' –C-O-H groups, the moment dipoles (μmph), and the permitivities (εmph) of the mobile phases. Most accurate prediction of the RM values of the tocopherols in all the mobile phases investigated, were achieved by use of two parametric equations employing the dipole moments of the mobile phases, and one topological index from among the topological indexes 2χν, oB, C, or the sum of the net electron charge ΣNEC).
