Type 2 DM is the most common type in diabetic populations. Inhibition of alphaglucosidase can ameliorate postprandial hyperglycemia that occurs in patients with type 2 DM. Adding antioxidants to the therapy of DM is intended to reduce complications caused by oxidative stress. Some species of &lt;em&gt;Garcinia&lt;/em&gt; have been proven to inhibit alpha-glucosidase and have antioxidant activity, but there is no research on &lt;em&gt;Garcinia fruticosa&lt;/em&gt; Lauterb. Therefore, the aims of this research were to determine the activity of &lt;em&gt;Garcinia fruticosa&lt;/em&gt; Lauterb. stem bark in inhibiting alpha-glucosidase and as an antioxidant. &lt;strong&gt;Methods:&lt;/strong&gt; In this research, the &lt;em&gt;Garcinia fruticosa&lt;/em&gt; Lauterb. stem bark was dried, grinded, and extracted by multistage maceration using n-hexane, ethyl acetate, and methanol. Inhibition of alpha-glucosidase test has been done &lt;em&gt;in vitro&lt;/em&gt; on concentrated extracts and measured by microplate reader at 400 nm. The antioxidant test has been done using DPPH scavenging method and was measured by microplate reader at 519 nm.&lt;strong&gt; Results:&lt;/strong&gt; Ethyl acetate extract is the most active extract for both test. IC&lt;sub&gt;50&lt;/sub&gt; values for inhibition of alpha-glucosidase test are 20.18 &amp;mu;g/mL that is more active than standard (acarbose) which has IC&lt;sub&gt;50&lt;/sub&gt; value 141.55 &amp;mu;g/mL. Meanwhile, IC&lt;sub&gt;50&lt;/sub&gt; value from an antioxidant test is 8.93 &amp;mu;g/mL that is not more active than standard (quercetin) which has IC&lt;sub&gt;50&lt;/sub&gt; value 2.51 &amp;mu;g/mL. &lt;strong&gt;Conclusion:&lt;/strong&gt; Phytochemical screening shows that the ethyl acetate extract contains alkaloids, flavonoids, glycosides, saponins, and tannins.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">273</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Nusaibah Zahratunnisa, Berna Elya*, Arikadia Noviani &lt;/strong&gt;&lt;/p&gt;
