THIN-LAYER CHROMATOGRAPHY OF SOME C21, C19 AND C18 STEROIDS

THIN-LAYER CHROMATOGRAPHY OF SOME C21, C19 AND C18 STEROIDS

The resolution of 30 different C21, C19 and C18 steroids by various solvent systems on silica gel chromatoplates was reported. Effective resolution of Δ4-pregnene, 5α, axial-equatorial hydroxyl epimers and positional isomers was successfully achieved. The differentiation between these compounds by u...

Zusammenfassung:The resolution of 30 different C21, C19 and C18 steroids by various solvent systems on silica gel chromatoplates was reported. Effective resolution of Δ4-pregnene, 5α, axial-equatorial hydroxyl epimers and positional isomers was successfully achieved. The differentiation between these compounds by using four different colour reagents has been also reported.
