Harvesting of the leaves was carried out at the age of 2, 4, and 6 months after plantation (2m, 4m, and 6m). Each leaves dry powder was refluxed with methanol 70% and followed by liquid-liquid partition using n-hexane, ethyl acetate (EtOAc), and water. All samples were evaluated toward inhibition of the alpha-glucosidase enzyme &lt;em&gt;in vitro&lt;/em&gt;. Total phenol levels were determined using Folin-Ciocalteu reagent. &lt;strong&gt;Results: &lt;/strong&gt;The results showed that EtOAc fractions of both plantation techniques exhibited the highest inhibition of alpha-glucosidase. The highest activity was demonstrated by the 4m-OA-EtOAc fraction (IC&lt;sub&gt;50&lt;/sub&gt;, 93.50 ppm) and followed by the 6m-OA-EtOAc fraction (IC&lt;sub&gt;50&lt;/sub&gt;, 98.13 ppm). Based on the kinetic study, the inhibition type of the two most active samples were categorized as a non-competitive type. Total phenolic contents were decreased in the following order: 6m-SH-EtOAc &amp;gt; 4m-OA-EtOAc &amp;gt; 6m-OAEtOAc &amp;gt; 4m-SH-EtOAc fraction. It was shown that there was no positive correlation between the strength of inhibition with total phenolic content. &lt;strong&gt;Conclusions:&lt;/strong&gt; This study concluded that Lampeni at open-air plantation harvested on fourth months demonstrated the highest alpha-glucosidase inhibitory activity, although there was no positive correlation between the inhibition activity and phenolic content.&lt;/p&gt;
