摘要
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.
