Antioxidant Activity and Total Phenolic Content in Two Alga Species from the Persian Gulf in Bushehr Province; Iran

Abdolali Movahedinia | Mohsen Heydari


Abstract: The antioxidant properties of methanol extracts in two brown and red algae were studied in the present research. The maximum amounts of phenolic compounds (2.420.35 mg gallic acid/g extract) as well as the best antioxidant activities according to such tests as Di Phenyl Picryl Hydrazyl (DPPH) and Ferric Reducing Ability of Plasma (FRAP) were measured in red alga Gracilaria corticata. Brown alga Sargassum tenerrimum ; had lower phenolic compounds (2.130.19 mg gallic acid/g extract) and antioxidant activities with the same tests. According to the results; both algae had no antioxidant activity with ABTS (mol / g extract) test (in 50mg/ml concentration). There were no significant differences (p>0.05) between the studied algae in phenolic compounds and antioxidant activities according to DPPH and FRAP tests. However; there were significant differences between the algae in phenolic compounds and antioxidant activities according to DPPH and FRAP tests (sig<0.05).
