Substrate for liquid chromatography and process for isolating and purifying fat-soluble substance by the liquid chromatography on the substrate
 A substrate for liquid chromatography comprising a spherical particle of highly cross-linked polymer which is produced from (a) 100 parts by weight of a monomer of vinyl ester, acrylate or methacrylate, these esters having a long alkyl chain, if desired, together with a comonomer copolymerizable with the monomer and (b) 10 to 80 parts by weight of a cross-linking agent copolymerizable with the monomer and having at least two functional groups, and a process for isolating and purifying a fat-soluble substance, for instance, a lower alkyl ester of eicosapentaenoic acid or docosahexaenoic acid by means of the liquid chromatography on the substrate.
