Total phenol content was determined by Folin-Ciocalteu&amp;rsquo;s reagent method and flavonoid was determined by aluminium chloride colorimetric method. The antioxidant assays evaluated were 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity, 2, 2&amp;rsquo;-Azino-bis-(3-ethyl) benzothiazoline-6-sulfonic acid (ABTS) radical cation scavenging activity and Ferric reducing antioxidant power. &lt;strong&gt;Results:&lt;/strong&gt; L. &lt;em&gt;siceraria&lt;/em&gt; peel possessed maximum phenol and flavonoid content in acetone and toluene extracts respectively. FRAP was maximum in acetone extract of peel. The peel extract demonstrated stronger DPPH activity with IC&lt;sub&gt;50&lt;/sub&gt; value of 111 &amp;mu;g/ml followed by pulp extract. The same extract was effective in scavenging ABTS radical with an IC&lt;sub&gt;50 &lt;/sub&gt;value of 39 &amp;mu;g/ml while other parts were ineffective. &lt;strong&gt;Conclusion:&lt;/strong&gt; This work demonstrated good antioxidant activity of L. &lt;em&gt;siceraria&lt;/em&gt; vegetable cultivated in India and recommends that the peel of this vegetable may be of interest from a functional point of view as a major source of natural antioxidant.&lt;/p&gt;&lt;p style=&quot;text-align:justify&quot;&gt;&lt;strong&gt;Key words:&lt;/strong&gt;&lt;em&gt;Lagenaria siceraria&lt;/em&gt;, antioxidant activity, DPPH, ABTS, FRAP, total phenol.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><custom1><style face="normal" font="default" size="100%">Sumitra Chanda, Pooja Moteriya, Hemali Padalia, Tejas Rathod and Yogesh Baravalia</style></custom1><section><style face="normal" font="default" size="100%">64</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Sumitra Chanda&lt;sup&gt;*&lt;/sup&gt;, Pooja Moteriya, Hemali Padaliya, Tejas Rathod and Yogesh Baravalia &lt;/strong&gt;&lt;/p&gt;&lt;p style=&quot;text-align: justify;&quot;&gt;Phytochemical, Pharmacological and Microbiological Laboratory Department of Biosciences, Saurashtra University - Rajkot, 360 005, Gujarat, India.&lt;/p&gt;</style></auth-address></record></records></xml>
