Abstract: Chondrus ocellatus collected in spring and autumn on the same seaside, respectively, was extracted by 95% ethanol. Antioxidant activities of extractions were determined by chemical methods to produce superoxide free radicals, hydroxide free radicals and lipid peroxide of rat liver microsome. The results indicated that Chondrus ocellatus collected in different seasons can all scavenge superoxide free radicals and hydroxide free radicals. At the same time, they all show activities to inhibit lipid peroxide of rat liver microsome to certain degree. In addition, they show significant difference between the two extractions from Chondrus ocellatus in different seasons.

Key words: spring, autumn, Chondrus ocellatus, extraction, antioxidant activities
