An aliquot of the extract is chromatographed in the heptane-propylene glycol system, giving discrete zones of androsterone and 8etiocholan-3a-ol-17-one. The materials whose mobilities on paper are more rapid than that of androsterone (botli effluent material and material eluted from the paper strip distal to tlie androsterone zone) are rechromatographed in the hei)tane-.
