Özet
In this study, the antioxidant activities and biochemical characteristics of Ulva rigida (Ulvophyceae)and Arthrospira platensis (Cyanophyceae) were determined. The extracts from two seaweed specieswere evaluated for their free radical scavenging activity, using the 1,1-diphenyl-2-picrylhydrazylhydrate (DPPH) method, their total phenolic, flavonoid, and condensed tannin contents, throughFolin–Ciocalteu, Quettier-Deleu, and Price methods, respectively. The extracts of two seaweedsshowed a low free radical scavenging capacity in comparison with commercial antioxidant BHT(butylated hydroxytoluene), and vitamin C. The extract of U. rigida demonstrated greater antioxidantpotential with a low IC50 (3.76±0.02 mg/g Ext.). The total phenolic contents were ranged from2.21±0.08 (U. rigida) to 8.59±0.62 (A. platensis) mg GAE/g of extract. The highest flavonoidcontent was found in A. platensis as 22.70±0.65 mg rutin/g of extract. The contents of condensedtannin were measured 3.01±0.11 mg CE/g of extract for A. platensis and 3.76±0.06 mg CE/g ofextract for U. rigida. According to results obtained, U. rigida and A. maxima possess antioxidantactivity and could be used in for future applications in medicine, functional foods, and agriculture.
