Abstract
A method is disclosed for extracting human chorionic somatomammotropin (HCS) which comprises the steps of separating from placental extract a proteinic fraction which contains such hormone, enriching the fraction so as to increase its HCS percentage contents, ultrafiltering and chromatographically analyzing until the liquor volume is gradually reduced and the components of the extract other than the expected hormone are removed.
