The aim of this study is to examine the antioxidant activity of various solvent Salicornia herbacea extracts. Salicornia was extracted with dichloromethane and methanol then fractioned with solvents of different polarity. The total phenol contents of extracts were carried out by the Folin-Ciocalteu, results varied between different extracts, dichloromethane has higher total phenol content (67.4 mg GAE/g), butanol (53.84 mg GAE/g) and aqueous extract (44.69 mg GAE/g). The highest contents of total flavonoids were observed for dichloromethane extract (21.09 mg QE/g) and butanol (16.07 mg QE/g). Antioxidant activities of Salicornia extracts were evaluated by using DPPH radical scavenging and β-carotene-linoleic acid bleaching. All extracts showed important antioxidant activity dichloromethane extract has the best IC50 (7.89 µg/ml) and the highest antioxidant activity coefficient (CAA 635, at 200 ppm) better than the synthetic antioxidant butylated hydroxytoluene (BHT).
