An ameliorant for the chemical treatment of cancer which contains a chromanol glycoside represented by the following general formula (1): (1) wherein R1, R2, R3, and R4 are the same or different and each represents hydrogen or lower alkyl; R5 represents hydrogen, lower alkly, or lower acyl; X represents a monosaccharide or oligosaccharide residue in which the hydrogen atom of a hydroxyl group may be replaced with lower alkyl or lower acyl; n is an integer of 0 to 6; and m is an integer of 1 to 6. The ameliorant is novel and safe. Even when used in a small amount in the chemical treatment of cancer, it effectively functions to enhance the carcinostatic activity of a carcinostatic substance and inhibits side effects of the treatment. |
