In this paper, the polysaccharides were extracted from wheat bran by ultrasonic-assisted enzymatic technology, and physicochemical properties, total sugar content, free radical -scavenging ability and antioxidant properties were also investigated. Results showed that wheat bran polysaccharides contained some starch and protein, and the total sugar content reached 42.48%. Moreover, wheat bran polysaccharides could scavenge hydroxyl free radical, superoxide anion and nitrite ion, and had good antioxidant properties in lipid peroxidation models of egg yolk and mouse liver.
