Antioxidative effects of Suaeda heteoptera Kitag. extracts were measured using thiobarbituric acid method.The results showed that extracts obtained with water,methanol and hexane gave significant resistance to the lipid peroxidation of linolenic acid and hexane extract showed the highest antioxidative activities.Mechanism of this antioxidative effect was studied using chemiluminescence.The results showed that extracts can effectively scavenge O -? 2 but have no effects on OH ?.This illustrated that the antioxidative effects were achieved by scavenging O -? 2 radical.
