Woods and leaves by FRAP method. &lt;strong&gt;Materials and methods:&lt;/strong&gt; Extraction done using n-hexane, ethyl acetate, and methanol. The methanol extract was determined antioxidant activity using the FRAP method and also determined the total phenols content, total flavonoids, and phytochemical screening. &lt;strong&gt;Results:&lt;/strong&gt; The antioxidant activity of wood extract was 4.74 ± 1.03 FeEAC (mol/g) while leaves extract 41.17 ± 1.99 FeEAC (mol/g). Total phenols content for wood extract 16.46 ± 3.51 mg GAE/g, for leaves extract 141.62 ± 10.54 mg GAE/g. The total flavonoids content for woods extract was 27.99 ± 0.62 mg QE/g for leaf extract 41.45 ± 5.83 mg QE/g. The compounds of woods and leaves are the same; it is consist of terpenoids, alkaloids, phenols, flavonoids, saponins, terpenoids, and negatives for anthraquinone. &lt;strong&gt;Conclusion: &lt;/strong&gt;The antioxidant activity of the leaves of &lt;em&gt;Sterculia stipulata&lt;/em&gt; Korth. is greater than its wood activities.&lt;/p&gt;
