We assessed the antioxidant activity of crude extracts from 24 rhodophyte species from Brittany coasts using three complementary methods (2,2-diphenyl-1-picryhydrazyl, reducing activity, and b-carotene-linoleic acid system). We also examined phenolic contents. Cytotoxic activities were determined with three different cancer cell lines. Four species (Aglaothamnion pseudobyssoides, Furcellaria fastigiata, Polysiphonia lanosa, and Heterosiphonia plumosa) had high antioxidant activity and high…
