The leaves of &lt;em&gt;Moringa oleifera&lt;/em&gt; and petals of &lt;em&gt;Hibiscus sabdariffa&lt;/em&gt; were extracted by cool maceration with distilled water and ethylacetate, independently for 48 hours using soxhlet extractor. The free radical scavenging activities of the extracts were determined spectrophotometrically. DPPH free radical was used to determine the free radical scavenging activities of the extracts. The reducing power efficacy of the extracts was determined by their ability to reduce Fe&lt;sup&gt;3&lt;/sup&gt;+ to Fe&lt;sup&gt;2&lt;/sup&gt;+ ions using FERAP. &lt;strong&gt;Results: &lt;/strong&gt;Ethylacetate extract of &lt;em&gt;Hibiscus sabdariffa&lt;/em&gt; petals had higher free radical scavenging efficacy and more reducing power with an inhibitory concentration (IC&lt;sub&gt;50&lt;/sub&gt;) of 1.57 mg/ml compared to the ethylacetate extract of &lt;em&gt;Moringa oleifera&lt;/em&gt; leaves which had an IC&lt;sub&gt;50&lt;/sub&gt; of 2.60 mg/ml. Phytochemical profile revealed that the predominant compounds in both extracts were flavonoids, phenols, and amino acids. &lt;strong&gt;Conclusion: &lt;/strong&gt;This study has established that ethylacetate extract of the Petals of &lt;em&gt;Hibiscus sabdariffa &lt;/em&gt;has more reducing power and free radical scavenging efficacy compared to ethylacetate extract of &lt;em&gt;Moringa oleifera &lt;/em&gt;leaves. These plant parts could serve as novel sources for clinically efficient antioxidants.&lt;/p&gt;
