Many of these isolates exhibit diversified biological activities, including cytotoxic activity. &lt;strong&gt;Objective:&lt;/strong&gt; The objective of this study is to determine cytotoxic activity of compound isolated from &lt;em&gt;Phoebe declinata&lt;/em&gt; againts MCF-7 (breast cancer cell line). &lt;strong&gt;Methods:&lt;/strong&gt; Extraction was done by reflux using n-hexane, antioxidant activity measured by DPPH method and reducing power method, cytotoxic activity measured by MTT assay using MCF-7 cell line, struture eucidation was confirmed by NMR. &lt;strong&gt;Results:&lt;/strong&gt; The antioxidant activity measured using DPPH method for 1 and 2 showed IC&lt;sub&gt;50&lt;/sub&gt; value of 6.42 and 11.80 &amp;mu;g/mL respectively and using reducing power method for 1 and 2 showed IC&lt;sub&gt;50&lt;/sub&gt; value of 7.02 and 13.74 &amp;mu;g/mL respectively. Compound (1) and (2) exhibited cytotoxic activity against MCF-7 cells with an IC&lt;sub&gt;50&lt;/sub&gt; value of 82.978 and 93.179 &amp;mu;g/mL. &lt;strong&gt;Conclusion:&lt;/strong&gt; Compound (1) and (2) exhibited antioxidant activity and cytotoxic activity against MCF-7.&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%">713</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Berna Elya&lt;sup&gt;1,2*&lt;/sup&gt;, Basah Katrin&lt;sup&gt;1&lt;/sup&gt;, Roshamur Cahyan Forestrania&lt;sup&gt;1&lt;/sup&gt;, Rosmalena Sofyan&lt;sup&gt;3,&amp;nbsp;&lt;/sup&gt;Ryan Adi Chandra&lt;sup&gt;3&lt;/sup&gt; &lt;/strong&gt;&lt;/p&gt;
