Abstract:
Object To evaluate the antioxidative activity of the high molecular weight polyphenols from Sargassum thunbeergii Kuntze and Sargassum kjellmanianum Yendo. Methods Three kinds of evaluation systems for antioxidative activity were adopted to test their efficiency to scavenge radicals (including hydroxyl free radical ?OH, superoxide redical O? 2 and DPPH? free radical). Results The high molecular weight polyphenols from the two kinds of brown algae had strong activity to scavenge the radicals above. Furthermore, they acted almost as the same level. Conclusion The high molecular weight polyphenols from the two kinds of brown algae had strong antioxidative activity, thus they are the potential, natural and marine antioxidants.
