Purified glycoproteins (GLP) from Codium decorticatum were studied for their antioxidant activity. In order to assess the antioxidant potential of GLP, antiradical activities were characterized by different biochemical methods, namely by evaluating their 2,2-diphenyl-1-picrylhydrazyl radical (DPPH), Hydroxyl (OH) radical, superoxide radical ( O2) and nitric oxide (NO) scavenging abilities. The presence of antioxidant activity could elevate the value of the seaweeds especially C. decorticatum as a food additive with improved nutritional properties.
Key words: Glycoprotein; Antioxidant activity; Green algae; DPPH; Reducing power; Codium decorticatum
