Radical scavenging activity of glycoprotein from oral-arms of jellyfish Rhopilema esculentum
This study was carried out to evaluate the radical scavenging activityof giycoprotein isolated from jellyfish Rhopilema esculentum,and the effect on which of temperature.The results showed glycoprotein had dose-dependent scavenging activities for superoxide anion radical and hydroxyl radical.The value IC50 of glycoprotein was 450μg·ml-1 while value IC5o of carnosine was 80μg·ml-1 for scavenging activities of superoxide anion radical,and the value IC50 of glycoprotein was 750μg·ml-1 while value IC5o of carnosine was 100μg.ml-1 for scavenging activities of hydroxyl radical.That suggest that the glycoprotein has strong radical scavenging activity but lower than camosine.Moreover,radical scavenging activity was stable at high temperature.
