J. Planar Chromatogr. 15, 59-66 (2002). RPTLC of methyl laureate, methyl myristate, methyl palmitate, methyl isostearate, methyl stearate, and methyl arachidate on kieselguhr impregnated with different amounts of paraffin oil, using two different mobile phases. The RM values of these compounds for all the stationary phases and mobile phases investigated could be correlated with the dipole moments of the mobile phases, with the percentage impregnation of the stationary phase, and with numerical values of one topological index from among those based on the distance matrix or on the adjacency matrix. TLC of methyl laureate, myristate, palmitate, isostearate, stearate, and arachidate on kieselguhr impregnated with 10% or 15% of paraffin oil in hexane with methanol - water 9:1 and ethanol - water 9:1. Visualization with bromothymol blue or with an aqueous 0.005% solution of new fuchsin.

J. Planar Chromatogr. 16, 369-373 (2003). TLC of rosmarinic acid and valerenic acid on amino-modified silica gel with 8 binary phases (methanol - water, ethanol - water, propanol - water, acetonitrile - water, THF - water, acetonitrile - buffer, and methanol - buffer), in which the concentration of organic modifier varied from 0 to 100%, with chamber saturation at 20°C. Visualization by spraying with sulfuric acid conc. - methanol 1:10 and heating for 10 min at 120°C. Visualization under UV.

J. Planar Chromatogr. 17, 143-146 (2004). TLC of oleic, elaidic, palmitic, stearic, ricinoleic acid, methyl ricinoleate, alpha-hydroxypalmitic acid, methyl alpha-hydroxypalmitate, 12-hydroxystearic acid, methyl 12-hydroxystearate, 9,10-dihydroxystearic acid, methyl 9,10-dihydroxystearate on RP-18 with methanol - water 19:1 and 9:1. Detection with iodine vapor.
