SEPARATION AND RETENTION BEHAVIOUR OF BENZIMIDAZOLE DERIVATIVES IN THIN LAYER CHROMATOGRAPHY ON SILICA GEL
The separation ability and retention behaviour of normal phase TLC on silica with eight nonaqueous eluents, has been studied by measuring the retention constants of a series of synthesized benzimidazoles. The separation ability and retention behaviour are discussed in terms of the nature of the solute and eluent....

RETENTION AND LIPOPHILICITY OF ESTRADIOL DERIVATIVES IN NORMAL- AND REVERSED-PHASE HIGH PERFORMANCE LIQUID CHROMATOGRAPHY
The retention behaviour and separation ability of some estradiol derivatives were studied by HPLC on silica and C-18 commercially available columns. The mobile phases used were: benzene-ethyl acetate, benzene-tetrahydrofuran, benzene-acetonitrile, isopropanol-water and tetrahydrofuran-water in various proportions. The results are discussed in terms...
