Abstract
The antioxidant activity of the lipid extracts of eight marine algae belong ing to the Cystoseira genus has been evaluated in a micellar model system. The activity has been ascribed to the presence in the extracts of tetrapren yltoluquinols, which are tocopherol-like compounds characteristic of these algae. Results have been expressed as relative antioxidant efficiency (RAE) , defined as the ratio of the antioxidant efficiency (AE) of the tested ext ract to that of alpha -tocopherol. From the results a composition-activity relationship has been deduced.
