Seaweeds are regarded as a prospective source of bioactive compound. In the current study, the algae Halimeda tuna have been extracted using hexane, chloroform and ethanol were tested for phenolic, tannin, flavonoid content. Also, in vitro antioxidant activity interms of DPPH, Hydroxyl, Superoxide, Nitric oxide radical scavenging assay and FRAP assay. The presence of higher point of phenolic, tannin and flavonoid content were identified from ethanolic extract. Also, a result of a greater rate of DPPH and superoxide radical scavenging activity was observed through chloroform extract. The hexane and ethanolic ectracts exhibited a good result for hydroxyl and nitric oxide scavenging activity. The test results implied Halimeda tuna to possess good antioxidant potential.
