Abstract
The invention relates to a method of isolating sterols in commercial quantities from sterol-containing material by subjecting a solution of this material to a column-chromatographic separation; for isolating cholesterol from cholesterol-containing material, silica gel is preferably used as a column packing and a mixture of, for example, heptane and acetone is preferably used as an eluent.
