Similarly the IC&lt;sub&gt;50&lt;/sub&gt; value of the standard ascorbic acid was found to be 81.85 &amp;mu;g/ml as compared to the MCFE which has an IC&lt;sub&gt;50&lt;/sub&gt; value of 148.0 &amp;mu;g/ml for nitric oxide scavenging activity. Acetylcholinesterase inhibition assay was performed by &lt;em&gt;in vitro&lt;/em&gt; method and the IC&lt;sub&gt;50&lt;/sub&gt; value of MCFE and neostigmine was found to be 31.84 &amp;mu;g/ml &amp;amp; 19.71 &amp;mu;g/ml respectively. Conclusions: The present study investigated the neuroprotective activity of MCFE and it was identified by both &lt;em&gt;in vitro&lt;/em&gt; and&lt;em&gt; ex vivo&lt;/em&gt; techniques that the phytoconstituents has the ability to improve the learning and memory function by inhibiting the acetylcholinesterase.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">900</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Srikanth Jeyabalan&lt;sup&gt;1*&lt;/sup&gt;, Kavimani Subramanian&lt;sup&gt;2&lt;/sup&gt;, Uma Maheswara Reddy Cheekala&lt;sup&gt;3&lt;/sup&gt;, Chitra Krishnan&lt;sup&gt;4&lt;/sup&gt; &lt;/strong&gt;&lt;/p&gt;
