After estimating the swelling properties and solvent regain. values of hydroxypropylated Sephadex G-50 (organophilic dertran gel), behavior of fat-soluble vitamins on the column was examined. The available fractionation range for gel filtration utilizing hydroxypropylated Sephadex G-50 as a bed and chloroform as an eluting solvent was found to be between 200 and 10,000 in the molecular weight, but the results on the separation of fat-soluble vitamins were not better than the previous reports (Vitamins, 39,176 (1969), 40,309 (1969)) using Sephadex LH-20. Therefore, the method would be available only for separation of compounds having large differences in their molecular size.
