Study on Antioxidant Activity of Grateloupia filicina Polysaccharide

Abstract

Abstract: Objective: To investigate the antioxidationc apability of the water-soluble polysaccharide in vitro isolated from Grateloupia filicina. Methods: The antioxidation ability and reducing power of water-soluble polysaccharide (WGZ-b) were evaluated. Results: The results showed that the high polysaccharide concentrations of Grateloupia filicina has higher reduction energy than BHT and PG. It also found that the polysaccharides antioxidative activity, shows scavenging effects are in the order: O2-·>DPPH>·OH. The half inhibit concentration (IC50) to DPPH; O2-· is 116, 84.0μg/ml. Conclusion: The water-soluble polysaccharides of Grateloupia filicina possess a strong antioxidation capability.

Key words: Grateloupia filicina, polysaccharides, antioxidant activity
