Abstract:

Objective: To investigate the antioxidant activity of raspberry glycoprotein (RGP) in vitro and in vivo. Methods: The antioxidant activity of raspberry glycoprotein in vitro was evaluated by determining its reducing power and scavenging capacities against hydroxyl, superoxide anion and DPPH free radicals. The activities of CAT, SOD and GSH-PX in serum, liver and brain tissues of mice were determined to evaluate the antioxidant activity of raspberry glycoprotein in vivo. Results: Raspberry glycoprotein significantly increased the activities of CAT, SOD and GSH-PX in serum, liver and brain tissues of mice, revealed strong reducing power, and effectively eliminated hydroxyl, superoxide anion and DPPH free radicals. Conclusion: Raspberry glycoprotein has obvious antioxidant effect.

Key words: raspberry, glycoprotein, free radical, antioxidation
