Medium polar steroids, separation

Medicinal agents, analysis of aromatic carboxylic acids used as, 913-915 Medium polar steroids, separation of, 974 Metal complex dyes, 1015,1017 Metal complexes, detection and identification of, 520-521... 

Sex hormones, corticosteroids, and sapogenins are the most important medium polar steroids and numerous solvent systems have been used to separate them. Based on the work of Hara and Mebe (18), the following conclusions can be drawn. Medium polar steroids can be separated using a medium polar system most of the applicable solvent systems contain one or two nonpolar solvents such as hexane, benzene or toluene and one medium polar solvent, e.g., chloroform, acetone, etc.
