The objective of this study is to analyze the antioxidant activities, total phenolics and flavonoids of the &lt;em&gt;P. americana &lt;/em&gt;seed extract.&lt;em&gt; P. americana&lt;/em&gt; seed extraction was obtained through maceration and reflux using a 70% ethanol solvent. The results obtained were compared in terms of yield productivity, with yields of 43.07 (%) and 39.58 (%) respectively. Phytochemical compounds extracted from &lt;em&gt;P. americana&lt;/em&gt; seeds were tested using the phytochemical screening method, the antioxidant activity assay, the total phenolic analysis, and the total flavonoid analysis. The phytochemical screening showed that &lt;em&gt;P. americana&lt;/em&gt; seeds contain flavonoids, saponins, phenols, tannins, alkaloids, and quinones. The antioxidant activity of the 70% ethanol extract of &lt;em&gt;P. americana &lt;/em&gt;seeds obtained by maceration and reflux method was 77.298 g/mL and 98.626 g/mL, respectively, meanwhile the IC&lt;sub&gt;50&lt;/sub&gt; values of vitamin C were 12.883 g/mL. The 70% ethanol extract of &lt;em&gt;P. americana &lt;/em&gt;seeds obtained by maceration and reflux method had total phenolic content of 276.96 mgGAE/g and 294.96 mgGAE/g, and total flavonoid content of 1.73 mgQE/g and 12.70 mgQE/g respectively. This simply implies that the 70% ethanolic extracts from &lt;em&gt;P. americana&lt;/em&gt; seeds obtained through maceration and reflux have strong antioxidant activity.&lt;/p&gt;
