Study of the antioxidant activity of phenolic extracts of A. halimus L and Haloxylon scoparium Pomel northern Sahara

The antioxidants are the subject of many studies, b cause in addition to their use as preservatives in food products by replacing the synthetic antioxidants, they inter vene in the treatment of many diseases. In this stu dy, we evaluated the antioxidant properties of leaves of atriplex ha limus L as well as flowers and stems of haloxylon s coparium pomel. Butanolic Fractions of flowers of the two pl ants have a higher total phenols content; the fract ion of ethyl acetate and butanol, for these two plants, presents a better total antioxidant capacity, and higher ac tivity to trap the DPPH radical, radical OH and the ABTS radical catio n.
