Kaempferol was reported for the first time from &lt;em&gt;Gomphrena serrata&lt;/em&gt;. Quercetin was separated and identified from the hydro alcoholic extracts &lt;em&gt;Alternanthera sessilis&lt;/em&gt; stems (RT 6.503, concentration 0.01mg/ml). The hydroalcoholic extract of &lt;em&gt;Euphorbia heterophylla&lt;/em&gt; stems (RT 6.588, concentration 0.01mg/ml) was also evaluated for the presence of quercetin. &lt;strong&gt;Conclusion:&lt;/strong&gt; The method developed is very useful tool for qualifying and quantifying the plant specimens as well as their 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%">439</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Mamillapalli Vani&lt;sup&gt;1*&lt;/sup&gt;, Shaik Abdul Rahaman&lt;sup&gt;2&lt;/sup&gt;, Avula Prameela Rani&lt;sup&gt;3 &lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
