Type 2 diabetes play role for the majority of cases of diabetes worldwide which is characterized by the increase of postprandial blood glucose level. Maintaining postprandial glucose level through inhibition of &amp;alpha;-glucosidase is one of the essential strategies in the treatment of diabetes. Inhibitory effect of &amp;alpha;-glucosidase was commonly used to identify active compounds potentially to treat diabetes. Natural resources have potency as antidiabetic that can be used in diabetes treatment. &lt;strong&gt;Objective:&lt;/strong&gt; The objective of the study is to separate active fraction in the crude extract of &lt;em&gt;Garcinia hombroniana&lt;/em&gt; leaves to facilitate obtaining a pure biologically active compound as the &amp;alpha;-glucosidase inhibitor. &lt;strong&gt;Methods:&lt;/strong&gt; Fractionation to separate active fraction was performed using column and thin layer chromatography methods while &amp;alpha;-glucosidase inhibitory activity assay was performed i&lt;em&gt;n vitro&lt;/em&gt; using spectrophotometric methods at &amp;lambda; 400 nm. &lt;strong&gt;Results:&lt;/strong&gt; Ethyl acetate and methanol extract of &lt;em&gt;G. hombroniana&lt;/em&gt; yielded 14 and 12 fractions, respectively. Two fractions with the higher percent inhibition compared to other factions are fraction 8 from ethyl acetate extract (FEA8) and fraction 3 from methanol extract (FM3). The IC&lt;sub&gt;50&lt;/sub&gt; values of FEA8, FM3 and acarbose are 16.370 &amp;mu;g/mL, 59.042 &amp;mu;g/mL, and 39.534 &amp;mu;g/mL respectively. &lt;strong&gt;Conclusion:&lt;/strong&gt; Fraction 8 from ethyl acetate extract of &lt;em&gt;G. hombroniana&lt;/em&gt; leaves (FEA8) was separated and known in this study as the most bioactive &amp;alpha;-glucosidase inhibitor agent compared with another extract, fractions, and acarbose.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">488</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Nita Triadisti&lt;sup&gt;*&lt;/sup&gt;, Rani Sauriasari, Berna Elya&lt;sup&gt;* &lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
