✦ Synopsis

The retention behaviour of a series of /I-carbolines in normal-phase chromatography was studied. Silica and amino phases in high-performance liquid (HPLC) and thin-layer chromatographic (TLC) systems were analyzed. The Snyder-Soczewinski approach was used to interpret the retention mechanism in relation to different solute, solvent and stationary phase characteristics. Amino and silica stationary phases, TLC and HPLC techniques and various solvent selectivities were compared. The molecular structure-retention relationship was also studied by means of the group contributions to retention and the electronic constant.
