Total polyphenols contents were determined using Folin- Ciocalteu reagent whereas flavonoids were evaluated by AlCl&lt;sub&gt;3&lt;/sub&gt; method. LC-MS/MS method was carried out to reveal the phytochemical composition of extracts. Some tests were used to evaluate the &lt;em&gt;in vitro&lt;/em&gt; antioxidant activity of extracts such as DPPH free radical scavenging assay, ABTS&lt;sup&gt;+&lt;/sup&gt; radical cation decolorization assay, OH&lt;sup&gt;•&lt;/sup&gt; radical scavenging assay, ferrous ion chelating, reducing power and β-caroten/linoleic acid bleaching assay. &lt;strong&gt;Results:&lt;/strong&gt; The results showed that the aqueous extract was richer on polyphenols and flavonoids comparing to the acetonic extract. The analysis by LC-MS/MS allowed to identify many phenolic compounds in extracts, predominated by rosmarinic acid. In addition, the extracts were found to possess a significant antioxidant activity. &lt;strong&gt;Conclusion:&lt;/strong&gt; Accordingly, it can be concluded that &lt;em&gt;M. rotundifolia&lt;/em&gt; is quite rich in phenolic compounds and has a good antioxidant activity.&lt;/p&gt;
