The determination of total phenolic and total flavonoid were performed by spectroscopic method, while the quercetin concentration were determined by high performance liquid chromatography (HPLC). The antioxidant activity was evaluated by 2,2-diphenyl-1-picrylhydrazyl (DPPH) method. &lt;strong&gt;Results:&lt;/strong&gt; Ethanolic extracts of &lt;em&gt;Moringa oleifera&lt;/em&gt; leaf from region with medium altitude (Sigi regency) showed higher total phenolic, total flavonoid, quercetin concentration and antioxidant activity than regions with low and high altitude (Parigi and Palu cities). &lt;strong&gt;Conclusion:&lt;/strong&gt; This study reveals the potency of standardized extracts of &lt;em&gt;Moringa oleifera&lt;/em&gt; growing in medium altitude (Sigi regency) to be developed as antioxidant herbal medicine.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">6s</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">s104</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Evi Sulastri&lt;sup&gt;1&lt;/sup&gt;, Muhammad Sulaiman Zubair&lt;sup&gt;1,*&lt;/sup&gt;, Nurafni Israyanti Anas&lt;sup&gt;1&lt;/sup&gt;, Syakila Abidin&lt;sup&gt;1&lt;/sup&gt;, Ririen Hardani&lt;sup&gt;1&lt;/sup&gt;, Risfah Yulianti&lt;sup&gt;2&lt;/sup&gt;, Aliyah&lt;sup&gt;2 &lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
