Phenolic contents and antioxidant activities were determined in the water and ethanol extracts from six species ofedible seaweeds, Phaeophyceae ( Laminaria japonica, Hizikia fusiformis and Undaria pinnatifida ), Rhodophyceae ( Porphyra tenera and Gracilaria verrucosa ) and Chlorophyceae ( Ulva lactuca ). The highest extraction yield was observed in water extract (pH 8.0) of G. verrucosa (44.23 %) and phenolic content was the highest in ethanolic (75%) extract of H. fusiformis (52.82 μg/mg). 25 % ethanolic extract from U. lactuca was found to have the highest DPPH radicals scavenging activity(19.29 %) and superoxide anion scavenging activitiy was higher in water extract (pH 8.0) from H. fusiformis (81.20 %) than that other seaweeds. Phenolic contents were strongly correlated with antioxidant activity in the six edible seaweeds extracts (R 2 =0.852). Taken together, these results indicate that H fusiformis may be a excellentsource for development of natural antioxidants. Key Words |
