%X The extraction and isolation of natural antioxidants with potential in reducing the incidences of oxidative stress in the body and their potential inclusion into functional foods is a major topic of research at present. In this study, the aim was to investigate food-friendly Accelerated Solvent Extraction  (ASE ) samples and a Viscozyme  hydrolysate of the brown macroalga Fucus spiralis Linnaeus for total phenolic content and antioxidant activities. Furthermore, the effect of ultra-filtration steps on the total phenolic content and antioxidant activities of the Fucus spiralis hydrolysate were also evaluated.ethanolic-aqueous and methanolic-aqueous ASE  extracts displayed high phenolic contents of 37.03¡À3.01 and 39.04¡À5.72 ¦Ìg phloroglucinol equivalents mg/sample, respectively. Both the Fucus spiralis Viscozyme  hydrolysate and ASE  extracts displayed in vitro antioxidant activities. Our findings suggest that food-friendly extracts of Fucus spiralis show potential as alternative sources of antioxidants.
