ABSTRACT:
Disclosed herein is a process for producing i-brassicasterol, comprising charging a mixture of i-sterols derived from a mixture of sterols including brassicasterol into a column packed with a filler obtained by chemically binding alkyl group(s) of 15 to 24 carbon atoms to silica, and subjecting said mixture of i-sterols to reversed-phase partition column-chromatography while using (i) an alcohol of one to three carbon atoms or a mixture therof, or (ii) a mixed solvent comprising more than 50% by volume of said alcohol(s) and a solvent other than said alcohol(s) as an eluent, thereby isolating and purifying i-brassicasterol.
