Abstract
Sodium alginate is a cheap and available biopolymer due to its biodegradability and hydrophilic properties, PH sensitivity and natural nature received more attentions. Therefore, the present study investigates and compares the antioxidant properties of alginate in different concentrations of brown algae of Sargassum vulgare and Padina pavonica. According to the results, both algae had high antioxidant activity and the total amount of phenol antioxidant activity in three concentrations (100, 150 and 200 mg/ml), and chelating ability in three concentrations (0.1, 0.5 and 1 mg/ml) in Sargassum alginate were high. Ehereas the Padina alginate had a higher percentage of free radical scavenging DPPH, hydroxyl free radical at concentrations (0.11 and 1.83 mg/ml), regenerative power at the concentrations 160 and 320 µg/ml. There was no significant difference in the inhibition of free superoxide radicals between both algae at any concentration intervals) p < /em>>0.05).
