✦ Synopsis

The retention indices of 28 C6-C10 and n-C1 1 alkylbenzenes were determined on silicone oil OV-101, UCON LB-550-X, Carbowax 20M and TCEP. Additionally, retention indices of the same compounds on squalane, PEG-4000 and Carbowax 1540 were taken from the literature for quantitative structure-retention investigations. A general mode for deriving adequate precalculation equations was used. Two different kinds of regressors were studied.

The best results, presented as the maximum discrepancy between the experimental and calculated retention indices, are 1.5 for squalane, 2.5 for OV-101, 2.9 for UCON, 2.4 for Carbowax 20M, 5.6 for Carbowax 1540,11.3 for PEG-4000 and 7 for TCEP. A very high correlation between the polarity of the studied phases and some of the regressors has been found.

## Abstract Chromatographic data for five dihydropyridine calcium antagonists (CAs) were obtained on β‐cyclodextrin column in the reversed phase HPLC. Interaction energies of solute‐cyclodextrin complexes formed by docking of different parts of the CAs' molecules into the cyclodextrin cavity were c
