The densitometric determination was carried out at 366 nm in reflection/absorption mode. The calibration curves were linear in the range of 100-600 ng per spot for caffeic acid and quercetin. &lt;strong&gt;Results:&lt;/strong&gt; During the analysis methanolic fraction of &lt;em&gt;Bauhinia tomentosa&lt;/em&gt; L. floral buds showed the pres&amp;not;ence of caffeic acid (0.02%) and quercetin (0.018%). &lt;strong&gt;Conclusion:&lt;/strong&gt; The proposed method is simple, precise, specific, accurate, less time consuming and cost effective. The statistical analysis of data obtained proves that the method is reproducible and selective and can be used for routine analysis of reported phenolic compounds in crude drug and extracts. The simultaneous quan&amp;not;tification of these compounds has not yet been reported in floral buds of &lt;em&gt;Bauhinia tomentosa&lt;/em&gt; which may be utilized for the proper standardization of the plant.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">773</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Abhishek Gupta&lt;sup&gt;1,2&lt;/sup&gt;, Harinath Dwivedi&lt;sup&gt;2&lt;/sup&gt;, AKS Rawat&lt;/strong&gt;&lt;sup&gt;&lt;strong&gt;1*&lt;/strong&gt; &lt;/sup&gt;&lt;/p&gt;

Total phenolic and, flavonoid contents were determined and the antioxidant potential was estimated by four assay&amp;rsquo;s viz. DPPH radical scavenging assay, ferric reducing power assay, total antioxidant capacity and 2-deoxy ribose assay. &lt;strong&gt;Results:&lt;/strong&gt; The species is rich in three phenolic acids, among which gallic acid (1708 ug/g) is in maximum concentration followed by caeffic acid (437 ug/g) and protocateuchic acid (337.7 ug/g). Total phenolic content was higher (10.5 mg/g) than flavonoid content (3.78 mg/g) and TAC was found at 0.137 mg/g ASE (ascorbic acid equivalent). IC&lt;sub&gt;50&lt;/sub&gt; of &lt;em&gt;D. palmatus &lt;/em&gt;extract for scavenging of hydroxyl radical by 2-deoxy ribose and DPPH was at concentration of 125.61 &amp;plusmn; 0.834 (&amp;mu;g/ml) and 353.71 &amp;plusmn; 0.663 (&amp;mu;g/ml) respectively. &lt;em&gt;In vitro &lt;/em&gt;antidiabetiv potential, via inhibition of alpha amylase enzyme through starch iodine and 3,5- DNS assay reveals the IC&lt;sub&gt;50&lt;/sub&gt; of extract at 146.31 &amp;plusmn; 0.415 ug/ml and 286.23 &amp;plusmn; 0.671 ug/ ml respectively. &lt;strong&gt;Conclusion:&lt;/strong&gt;&amp;nbsp;The species (aerial part) was rich in phenolic acid with potential bioactivity, identified leads will be useful&amp;nbsp;in further chemical characterization and pharmacological validation.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue><section><style face="normal" font="default" size="100%">483</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Ankita Misra, Pushpendra Kumar Shukla, Bhanu Kumar, Abhishek Niranjan, AKS Rawat and Sharad Srivastava&lt;sup&gt;* &lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
