There is no report about pharmacognosy and phytochemical study with this plant.&lt;strong&gt;Objective:&lt;/strong&gt; The main aim of this research is to establish pharmacognosy, phytochemical study and antioxidant activity of &lt;em&gt;Sterculia rubiginosa&lt;/em&gt; Zoll.ex. Miq. Leaves. The plant used to cure many diseases of Indonesia. &lt;strong&gt;Methods:&lt;/strong&gt; In the present study, pharmacognosy and phytochemical study of plant material were performed as per the Indonesian Herb Pharmacopoeia. &lt;strong&gt;Results:&lt;/strong&gt; Microscopy powder of &lt;em&gt;Sterculia rubiginosa&lt;/em&gt; Zoll.ex. Miq. Leaves shows star shape trichoma as a specific fragment. Physicochemical parameters including total ash (17,152 %), acid-insoluble ash (0,922 %), water-soluble extractive (1,610 % w/w), alcohol-soluble extractive (4,524 % w/w), hexane-soluble extractive (4,005 % w/w), and ethyl acetate-soluble extractive (3,160 % w/w) were evaluated. Phytochemical screening of ethanol extracts showed the presence of tannins, flavonoids, alkaloids, steroids-terpenoids, glycosides, and phenols. And absent of saponins and Anthraquinones. Antioxidant activity with IC&lt;sub&gt;50&lt;/sub&gt; 157, 4665 ppm and flavonoid total was 59,436 mg/g quercetin equivalent. &lt;strong&gt;Conclusion:&lt;/strong&gt; The pharmacognosy, physiochemical, and phytochemical evaluation provides information for the safety, identification, and class of chemical constituent&amp;rsquo;s presents in this crude extract.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">3</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">571</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Rini Prastiwi&lt;sup&gt;1,2*&lt;/sup&gt;, Berna Elya&lt;sup&gt;2&lt;/sup&gt;, Rani Sauriasari&lt;sup&gt;3&lt;/sup&gt;, Muhammad Hanafi&lt;sup&gt;4&lt;/sup&gt;, Ema Dewanti&lt;sup&gt;1&lt;/sup&gt; &lt;/strong&gt;&lt;/p&gt;
