The samples antioxidative and radical scavenging capabilities of 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical cation and ferric reducing power were determined. Total phenolic, tannin and flavonoid contents of EaE extract were evaluated. &lt;strong&gt;Results:&lt;/strong&gt; Six compounds were isolated. Three were the methoxyisoflavones5- 7-dihydroxy-4′-methoxyisoflavone &lt;strong&gt;(1),&lt;/strong&gt; 7-hydroxy-4′methoxyisoflavone&lt;strong&gt; (2),&lt;/strong&gt; 5,4'-dihydroxy-7- methoxy-isoflavone&lt;strong&gt; (3),&lt;/strong&gt; along with isorhamnetin &lt;strong&gt;(4)&lt;/strong&gt; and two quercetin derivatives quercetin 3-glucoside &lt;strong&gt;(5) &lt;/strong&gt;and quercetin 3-rutinoside &lt;strong&gt;(6) &lt;/strong&gt;were isolated. The hydroalcoholic extract, fractions and 4'-methoxyisoflavones showed radical scavenging effect in the order of EaE &amp;gt; TeE &amp;gt; BuE &amp;gt;compound&lt;strong&gt; 1&amp;gt;&lt;/strong&gt;compound&lt;strong&gt; 2&amp;gt;&lt;/strong&gt; HeE. Stimulation of both sero-responses was observed, especially this of EaE. The results showed an increase of macrophage cells, lymphocyte and antibody titers in blood. &lt;strong&gt;Conclusion:&lt;/strong&gt; The presence of 5-hydroxyl group at A-ring may be important to show the immunostimulant and antioxidant activity of compound &lt;strong&gt;1&lt;/strong&gt;vs compound &lt;strong&gt;2&lt;/strong&gt;. The present results showed the potential abilities of EaE as antioxidant and immunomodulator agent and these would impart healthy economic benefits in vaccinated birds.&lt;/p&gt;
