Antioxidant Activity of the Chitosan Extracted from Shrimp Exoskeleton

Abstract

The chitosan were isolated from shrimp exoskeleton. The Extracted chitosan have antioxidant and cytotoxic potentials were investigated byemploying various analysis such as 1,1-diphenyl-2-picrylhydrazyl (DPPH)/superoxide/ hydroxyl radicals scavenging, reducing power, iron ion chelating and total antioxidant activity. The extracted chitosan have potentialantifungal and cytotoxic activity were studiedat various concentrations.
