(HPL), &lt;em&gt;Herba Verbena Officinalis&lt;/em&gt; (HVO), and &lt;em&gt;Valeriana officinalis&lt;/em&gt; L.

In addition, their free radical scavenging abilities were studied by ftheir interactions with the stable radicals of 2, 2&amp;rsquo;-azino-bis-(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) and 2,2-diphenyl-1-picrylhydrazyl (DPPH). &lt;strong&gt;Results:&lt;/strong&gt; The results indicated that the HPL ethanolic extract exhibited greater antioxidant activity (1.2688 &amp;plusmn; 0.01 mmol Trolox/g) than the HVO ethanolic extract (1.1686&amp;plusmn; 0.043 mmol Trolox/g) and the VO ethanolic extract (0.2579 &amp;plusmn; 0.0031 mmol Trolox/g) as compared to Nilestriol (0.0026&amp;plusmn;0.0012), a positive control agent in the experiment. Moreover, the HPL extract showed remarkable free radical scavenging activity against ABTS&lt;strong&gt;&amp;bull;&lt;/strong&gt;+, and the HVO extract was the most potent against DPPH&lt;strong&gt;&amp;bull;&lt;/strong&gt;. &lt;strong&gt;Conclusion:&lt;/strong&gt; These activities may be attributed to the total flavonoid or phenolic acid contents of among these extracts.&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%">198</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Yi-ming Li&lt;sup&gt;1&lt;/sup&gt;, Yan-Ru Liu&lt;sup&gt;2,3&lt;/sup&gt;, Bing-Kun Xiao&lt;sup&gt;2&lt;/sup&gt;, Jian-Yun Yang&lt;sup&gt;2&lt;/sup&gt;, Rong-Qing Huang&lt;sup&gt;2*&lt;/sup&gt; &lt;/strong&gt;&lt;/p&gt;
