Sterol intermediates in cholesterol biosynthesis have been resolved by a three-step chromatographic procedure.128 A detailed study of reversed-phase thin-layer chromatography of a wide variety of steroids (on silanized silica gel) includes a correlation of AJ M values of substituents with hydrophobicity parameters.129... 

Chromatographic parameters obtained from reversed-phase thin-layer chromatography are occasionally used as substitutes for partition coefficients [226 — 229]. Silica gel plates, being coated with hydrophobic phases (nowadays being commercially available), are eluated with aqueous/organic solvent systems of increasing water content. Eq. 26 converts the resulting R, values to R, values, which are true measures of lipophilicity.

From the general framework of the Snyder and Soczewinski model of the linear adsorption TLC, two very simple relationships were derived, which proved extremely useful for rapid prediction of solute retention in the thin-layer chromatographic systems employing binary mobile phases. One of them (known as the Soczewinski equation) proved successful in the case of the adsorption and the normal phase TLC modes. Another (known as the Snyder equation) proved similarly successful in the case of the reversed-phase TLC mode.
