The plant material was extracted with methanol and the methanolic extract was screened (&lt;em&gt;in-vitro&lt;/em&gt;) for its antioxidant activity using ABTS and DPPH assays. The potential antidiabetic activity of the plant extract was evaluated against some carbohydrates (α- amylase and α-glucosidase) and lipid (pancreatic lipase) digestive enzymes. The inverted intestinal sac model was also used to investigate the effect of the extract on intestinal glucose absorption. The anti-protein glycation activity of the extract was determined using haemoglobin. &lt;strong&gt;Results:&lt;/strong&gt; The phytochemical screening revealed the presence of most of the phytochemicals (Tannins, Flavonoids, Terpenoids, Alkaloids etc) that were screened for. The crude extract exhibited the antidiabetic potential as it significantly (&lt;em&gt;P&lt;/em&gt;&amp;lt; 0.05) inhibited α-glucosidase and pancreatic lipase in a dose dependent fashion. The extract also effectively reduced intestinal glucose absorption. The extract further showed antioxidant activity by efficiently scavenging ABTS and DPPH radicals with IC&lt;sub&gt;50&lt;/sub&gt; values of 68.3 μg/ml and 308 μg/ml, respectively. The extract also inhibited haemoglobin glycation, thus displaying the anti-protein glycation potential. &lt;strong&gt;Conclusion:&lt;/strong&gt; It is apparent that &lt;em&gt;E. ferox&lt;/em&gt; extract could serve as scaffold for diabetic therapy. For future study, cytotoxicity profile and &lt;em&gt;in vivo&lt;/em&gt; investigation of the antidiabetic activity of the crude extract are essential.&lt;/p&gt;

Crude extracts were prepared using various solvents (hexane, acetone, ethylacetate, methanol, dichloromethane respectively), and percentage yields calculated. The antioxidant activities of crude extracts were monitored with DPPH, ABTS and nitric oxide (NO) radicals using spectra techniques. &lt;strong&gt;Results: &lt;/strong&gt;The phytochemical presents in &lt;em&gt;Lippia javanica&lt;/em&gt; were tannin, flavonoids, terpenoids, alkaloids and phenols. Percentage yield increased in order; Acetone &amp;gt; Methanol, &amp;gt; Dichloromethane &amp;gt; Ethyl-acetate &amp;gt; Hexane. All the crude extracts showed differ degrees of antioxidant potential as evidence by significantly (&lt;em&gt;P&lt;/em&gt; &amp;lt; 0.05) scavenging DPPH, ABTS and NO radicals, Acetone crude extract showed the lowest IC&lt;sub&gt;50&lt;/sub&gt; (2.22 × 10&lt;sup&gt;-3&lt;/sup&gt; and 2.42 × 10&lt;sup&gt;-3 &lt;/sup&gt;mg/ml) toward DPPH and ABTS radical respectively in comparison to other crude extracts, and the positive controls (Ascorbic acid and Butylated hydroxyl anisole), Hexane crude extract showed the lowest IC&lt;sub&gt;50&lt;/sub&gt; (3.95 × 10&lt;sup&gt;-1 &lt;/sup&gt;mg/ml) toward NO radical compared with other treatments.&lt;strong&gt; Conclusion:&lt;/strong&gt; Therefore, this study proves that &lt;em&gt;Lippia javanica &lt;/em&gt;crude extracts are good source of natural antioxidants in alleviating oxidative stress diseases. Isolation of bioactive compounds from crude extracts are desirable for future studies.&lt;/p&gt;
