Abstract

In this study, pharmacological properties of three native macro algae which collected from the shores of the Chabahar Gulf (the Omean Sea) including: Ulva lactuca, Sargassum ilicifolium and Nizimuddinia zanardini were evaluated. The methanol extracts of three species of green, brown and red algae were. The concentration of β-carotenoid, phenolic Compound and antioxidant activities (AOA) was analyzed by routine methods. Based on the results, different antioxidant properties were observed among algae. These results probably was associated with antioxidant compounds of algae. In the species of U. lactuca, S. ilicifoliumand N. zanardini the amount of β-carotenoid was measured 0.56, 0.048 and 0.041 mg/100DW, total phenol was 0.206, 0.396 and 0.133 mg GA/g DW and inhibitory activity of free radicals (DPPH) was in the range of 45.7-60.4%, 51.6-61.8% and 9.6-28%, respectively (p < 0.05). Based on obtaining results, the highest level of β- carotenoid was observed in the U. lactuca extract and the highest level of total phenol and inhibitory activity of free radicals (DPPH) was observed in S. ilicifolium extract. Overall, the results of this study indicated that all three species of algae have usability as a primary substance in food and drug industry.
