Popis: The Salicornia species have been used for treatment and prevention of a various diseases. To the best of my knowledge, little information is regarding the antioxidant and protective activities of lipid extract from Salicornia Arabica (SALE). The objectives of this present work were designed to determine the in vitro antioxidant activities of SALE against cadmium-induced toxicity in erythrocytes isolated from rats. The distribution of fatty acid reflected the richness in saturated fatty acids that were predominated by palmitic acid. Our analysis showed that the major fatty acid components were palmitic acid (47.78%), linoleic acid (17.75%), followed by nanadecenoic acid (10.96%). Minor fatty acids including lignoseric acid and palmatoleic acid (C16:0). The in vitro antioxidant activity of SALE was evaluated using both test DPPH and ABTS assays. An important antioxidant potential was observed. The protective potential of SALE was evaluated by estimating the levels of stress markers like MDA concentration and SOD, CAT and GPx activities. Our results showed that cadmium significantly decreased the SOD, CAT and GPx activities in erythrocytes homogenates and enhanced lipid peroxidation. The pre-treatment with SALE ameliorated antioxidant status and inhibited MDA level in erythrocytes. In conclusion, the lipid isolated from S. arabica showed protective potential against Cd-induced erythrocytes damage, which could be related to active compounds present in this fraction.
