Then, the &lt;em&gt;C. trifolia&lt;/em&gt; leaf extracts were assessed for antioxidant activity by the DPPH and ABTS radical scavenging and FRAP assay. Total phenolic and flavonoid contents were determined by the Folin- Ciocalteu and aluminum chloride colorimetric methods, respectively. Antidiabetic activity was evaluated by determination of α-glucosidase inhibitory effect. &lt;strong&gt;Results:&lt;/strong&gt; Preliminary phytochemical analysis of ethanol and 50% ethanol extracts of &lt;em&gt;C. trifolia&lt;/em&gt; leaves showed positive results for alkaloids, coumarin, tannins, saponins, cardiac glycosides, terpenoids, and steroids. The 50% ethanol extract had the best antioxidant activities of the three antioxidant assays (&lt;em&gt;p&lt;/em&gt; &amp;lt; 0.05). The results revealed higher phenolic and flavonoid contents in 50% ethanol extract than in the other extracts (p &amp;lt; 0.05). Moreover, the 50% ethanol extract exhibited the best potential as α-glucosidase inhibitors of all the extracts and acarbose (&lt;em&gt;p &lt;/em&gt;&amp;lt; 0.05). &lt;strong&gt;Conclusions:&lt;/strong&gt; The results conclude that the &lt;em&gt;C. trifolia&lt;/em&gt; leaves with 50% ethanol as the solvent possessed the potential to extract the highest levels of phytochemical content and have potential antioxidant and α-glucosidase inhibitory activities for diabetic therapy.&lt;/p&gt;
