The antioxidant activity of the ethanolic extract was evaluated &lt;em&gt;in vitro&lt;/em&gt; by the DPPH (2,2-diphenyl-1-picrylhydrazyl) test, the FRAP assay and &amp;beta;-carotene bleaching assay. &lt;strong&gt;Results:&lt;/strong&gt; sixty-four compounds are identified by GC/MS analysis, six are predominant: &amp;alpha;-linoleic acid (24.20%), linoleic acid (23.58%), Stigmasterol (8.53%), 2-Metyl-Z-4-tetradecene (6.62%) And &amp;alpha;-Bisabolol (1.70%). The free radical scavenging by DPPH method indicated that the ethanolic extract of &lt;em&gt;C. suffruticosa&lt;/em&gt; showed a very high antioxydant activity with an IC&lt;sub&gt;50&lt;/sub&gt; = 0.017 &amp;plusmn; 1.00 mg / ml. This extract also showed an ability to reduce very high iron with a maximum optical density of 1.157 at a concentration of 0.5 mg / ml and an antioxidant activity compared to the &amp;beta;-carotene / linoleic acid test of order of 75 &amp;plusmn; 1.02%. &lt;strong&gt;Conclusion:&lt;/strong&gt; These results show for the first time the richness of phytochemicals and the strong antioxidant activity of the species &lt;em&gt;Calendula suffruticosa&lt;/em&gt; endemic to north-east of Algeria.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">64</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p&gt;&lt;strong&gt;Sofiane Ismahene&lt;sup&gt;1&lt;/sup&gt;*, Seridi Ratiba&lt;sup&gt;1&lt;/sup&gt;, Cortes Martinez Diego Miguel&lt;sup&gt;2&lt;/sup&gt;, Cabedo Nuria&lt;sup&gt;2&lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
