A grafted chromatographic filler comprising an inorganic carrier having hydroxy groups on its surface to which a-arylalkylamine derivative is grafted, said a-arylalkylamine derivative comprising asymmetric carbon- containing, optically active a-arlylalkylamine and aminoalkylsilane being connected to each other via a dibasic carboxylic acid, and a method for separating an enantiomer mixture using the filler as a stationary phase of liquid phase chromatography. The filler can be easily prepared by usual chemical reactions, is chemically stable, and shows excellent effect of separating enantiomer mixtures of compounds containing -NH-, -CONH- or -OCO-group into each other.
