	abstract = {<p>The present work studies the antioxidant activities and antimicrobial properties of the aerial part of Retama sphaerocarpa. The secondary metabolites (polyphenols) were extracted using different solvents: chloroform, ethyl acetate and n-butanol. In each fraction, total polyphenols and flavonoids were respectively quantified using Folin-Ciocalteu test and aluminium chloride colorimetric method. The concentration of polyphenols was higher in the chloroform extract (121.4 +/- 0.3 mg GAE/g), than in n-butanol extract (111.7 +/- 0.1 mg GAE/g) and ethyl acetate extract (73.0 +/- 0.4 mgGAE/g). The evaluation of flavonoids content also showed a high value of flavonoid in chloroform extract (20.9 +/- 0.2 mg QE /g DM), whereas the ethyl acetate and the n-butanol extracts of Retama sphaerocarpa leaves contained similar quantity of flavonoids with 16.5+/- 0.8 mg QE /g DM and 15.3+/- 0.7 mg QE/g DM, respectively. The obtained extracts of R. sphaerocarpa were also evaluated for their antioxidant activities using DPPH radical-scavenging method. The three extracts (i. e. chloroform, ethyl acetate and n-butanol extracts) showed very high free radical scavenging activity: 73 +/- 0.8, 75.6 +/- 1.9 and 81.5 +/- 0.3 (\%), respectively. We also investigated the antimicrobial activities of the three extracts using the disc diffusion method. Each of the three extracts were active against Bacillus sp.</p>},
