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;

Some natural substances with antioxidant activity proved capable of inhibiting the activity of the enzyme XO. Pharmacological benefit of polyphenol compounds had been proved. Gambir (&lt;em&gt;Uncaria gambir&lt;/em&gt;) Hunter Roxb, a native plant, had been proved antioxidant activity, so that it had potential to be developed as an inhibitor of the XO. This study aimed to evaluate the activity of Gambir as XO inhibitor. &lt;strong&gt;Methods:&lt;/strong&gt; These extracts of Gambir were preparation from Gambir and Gambir leaf using ethanol 50% and ethanol 96%, respectively. The polyphenol content and Xanthine oxidase inhibitory activity was evaluated by spectrophotometry, meanwhile analysis of (+)catechin was determined by high pressure liquid chromatography (HPLC). &lt;strong&gt;Results:&lt;/strong&gt; Screening XO inhibitory activity &lt;em&gt;in vitro&lt;/em&gt; showed that ethanolic 96% extract of Gambir leaf showed the highest activity, i.e. 50% relative to standard allopurinol at the final concentration of 100 ppm. &lt;strong&gt;Conclusion:&lt;/strong&gt; There was no positive correlation between XO inhibitory activity and polyphenol or (+)catechin content.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">862</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Eriawan Rismana&lt;sup&gt;1*&lt;/sup&gt;, Sri Ningsih&lt;sup&gt;1&lt;/sup&gt;, Fachry Fachrudin&lt;sup&gt;2&lt;/sup&gt; &lt;/strong&gt;&lt;/p&gt;
