title: [Structure-mobility relationships in thin-layer chromatography. Applications to some progestogens (author's transl)].
abstract: A study has been made on the quantitative relationship between the chromatographic mobility and the structure of progestogenic steroids. The coefficient K, corresponding to the fundamental skeleton, and the parameters of different substituents were calculated from the RM values. The results obtained with eighteen steroids tested in two solvent systems of low dielectric constant and low polarity have been improved satisfactorily.
