The location and tentative identification of steroids on paper chromatograms by means of a system of color tests

Chromatography

“…Repeated solvent development sharpens the zones and increases resolution (942). Improved detection methods have been proposed for sterols (44,558,1157), estrogens and ketosteroids (43,44,558), pregnane derivatives (43-5, 100, 472, 558), and digitalis glycosides (471).…”
