PURPOSE:To optically resolve a sulfoxide useful as an intermediate for organic synthesis by a simple method, by carrying out the optical resolution of an enantiomer mixture of a sulfoxide derivative using a readily available and inexpensive polysaccharide derivative as a separating agent. CONSTITUTION:An enantiomer mixture of a solfoxide derivative having a partial skeleton expressed by the formula is optically resolved using a separating agent, e.g. cellulose tribenzoate, containing a polysaccharide derivative as an active ingredient by chromatography. The separating agent for the chromatography is preferably granular and the size thereof is preferably 1mum-10mm in a porous form.
