Abstract: In this experiment, ability of anti-oxidation of phycocyanin in Nostoc sphaeroids Kutz by anti-oxidation experiment with non-lipid system and anti-oxidation in vitro was studied. The results indicated that relationship between concentration and scavenging effect of phycocyanin on superoxide free radical (O·2), hydroxyl free radical (·OH) and peroxide hydrogen (H2O2) was evident. Contents of MDA and peroxide in blood and liver of mice were reduced in vitro, so phycocyanin could cell protect membrane and erythrocyte. Obviously, phycocyanin in Nostoc sphaeroids Kutz could protect rat liver plastomasme from being damnified and effected evidently on ability of anti-oxygen of blood plasma.

Key words: Nostoc sphaeroids Kutz, phycocyanin, antioxidation activity
