In this paper,rape bee pollen was used as the research object.Four types of rape bee pollen protein,including water-soluble,ethanol-soluble,salt-soluble and alkali-soluble protein were extracted by their different dissolving abilities.The antioxidant activities were investigated.The results showed that the contents of water-soluble protein,ethanol-soluble protein,alkali-soluble protein and salt-soluble protein were 7.35 %,3.65 %,2.50 %,and 2.24 %,respectively.All four protein components from rape bee pollen had antioxidant activity.The relationship between concentration and the total antioxidant power,the scavenging power on DPPH,OHo,and O-2o all showed positive correlation with the concentration.Antioxidant activity from strong to weak was in the following order: water-soluble protein>ethanol-soluble protein>alkali-soluble protein>salt-soluble protein.Therefore,rape bee pollen proteins have the potential as natural antioxidant.
