However, systematic study on phytochemistry and pharmacology of&lt;em&gt; Berberis&lt;/em&gt; species from Nepal is lacking. &lt;strong&gt;Objectives:&lt;/strong&gt; To evaluate the antioxidant activity, total phenolic and flavonoid contents of &lt;em&gt;Berberis&lt;/em&gt; aristata and &lt;em&gt;Berberis thomsoniana&lt;/em&gt; from Sagarmatha National Park. &lt;strong&gt;Materials and Methods:&lt;/strong&gt; Antioxidant activity was measured through 2, 2-Diphenyl-1-Picrylhydrazyl assay. Total phenolic and flavonoid content were estimated using Folin&amp;ndash;Ciocalteau and aluminum chloride method respectively. &lt;strong&gt;Results:&lt;/strong&gt; Samples showed dose-dependent radical scavenging activity. Radical scavenging activity of the methanolic extracts of different parts of &lt;em&gt;B. aristata&lt;/em&gt; and &lt;em&gt;B. thomsoniana&lt;/em&gt; ranged from 19.38 to 98.47%, with leaf extracts of &lt;em&gt;B. thomsoniana&lt;/em&gt; showing the strongest activity. The total phenolic content of the samples varied from 11.04 to 65.30 mg GAE g&lt;sup&gt;-1&lt;/sup&gt; dry weight whereas total flavonoid content was in between 2.4 to 16.46 mg quercetin/g dry weight. &lt;strong&gt;Conclusion:&lt;/strong&gt; Among the tested samples, leaf extracts of &lt;em&gt;B. thomsoniana&lt;/em&gt; showed the strongest antioxidant activity and contained the highest amount of total phenolic and flavonoid content.&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%">s167</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Lok Ranjan Bhatt*, Bina Wagle, Minu Adhikari, Santoshi Bhusal, Anjana Giri, Shandesh Bhattarai &lt;/strong&gt;&lt;/p&gt;
