The n-hexane, dichloromethane and ethyl acetate fractions were prepared by successive partition process of the methanol extract. Antioxidant activities were evaluated by various antioxidant assays, including DPPH (1,1-diphenyl-2-picrylhydrazyl), FRAP (ferric reducing antioxidant power), CUPRAC (&lt;em&gt;cupric reducing antioxidant capacity&lt;/em&gt;), and ABTS (&lt;em&gt;2,2’-azonobis 3-ethylbenzothiazoline-6-sulfonic acid&lt;/em&gt;) method. Total phenolics were estimated based on the Folin–Ciocalteu method, while, aluminum chloride methods were employed to estimate total flavonoids. Antidiabetic activies was determined by inhibiting the activity of α-glucosidase method. Results: antioxidant activity assay against DPPH radical as well as the total phenolic and flavonoid content of &lt;em&gt;L. bancanus&lt;/em&gt; leaves showed that the methanol extract possessed IC&lt;sub&gt;50&lt;/sub&gt; value of 39.469 ± 0.273 μg/mL with total phenol and flavonoid were 11.426 ± 0.432 mg GAE/g dry weight sample and 15.423 ± 0.213 mg QE/g respectively. The FRAP, CUPRAC and ABTS values of methanol extract were 3494.302 ±0.456, 26665.501 ± 5.940 and 2857.977 ± 0.715 μM TE/g dry weight sample respectively. Antidiabetic activity of methanol extract with IC&lt;sub&gt;50&lt;/sub&gt; value of 30.565 ± 0.331 μg/mL. Conclusion: It could be concluded that leaves of &lt;em&gt;L. bancanus&lt;/em&gt; have antioxidant and antidiabetic properties.&lt;/p&gt;
