Miers ex Hook F and Thomas commonly called as gudduchi or amrita is a widely used plant in traditional medicinal system of Ayurveda. A UPLC MS/MS Q-tof method for the identification and characterization of berberine in &lt;em&gt;Tinospora cordifolia&lt;/em&gt; (Willd.) Miers. ex HooK.F. and Thomas. and to evaluate the anti inflammatory potential of bioactive fraction. &lt;strong&gt;Materials and Methods:&lt;/strong&gt; The presence of berberine in &lt;em&gt;Tinospora cordifolia&lt;/em&gt; was determined by HPLC and was subsequently isolated by HPTLC. The anti inflammatory property of the fraction containing berberine was demonstrated to have an inhibitory activity on 5 lipoxygenase, an enzyme involved in inflammatory pathway and its IC&lt;sub&gt;50&lt;/sub&gt; value was obtained. The binding interactions between berberine and 5-LOX were demonstrated by docking studies. &lt;strong&gt;Result:&lt;/strong&gt; The presence of berberine in &lt;em&gt;Tinospora cordifolia&lt;/em&gt; methanolic extract was identified by HPLC and HPTLC analysis and confirmed by UPLC MS/ MS Q-tof. The fraction containing berberine inhibited 5-LOX with an IC&lt;sub&gt;50&lt;/sub&gt; of 0.041&amp;plusmn; 0.0003&amp;mu;g/mL as compared to that of NDGA (positive control) which showed an IC&lt;sub&gt;50&lt;/sub&gt; of 2.75 &amp;plusmn; 0.05 &amp;mu;g/mL. Molecular docking of berberine with 5-LOX showed a binding energy of -8.942 &amp;plusmn; 0.039665 kcal/mol and Ki of 273.16 &amp;plusmn; 3.026 nM as compared to the NDGA which has a binding energy of -7.186 &amp;plusmn; 0.170503 kcal/mol and Ki 5.604&amp;plusmn; 1.618 &amp;mu;M. &lt;strong&gt;Conclusion:&lt;/strong&gt; &lt;em&gt;Tinospora cordifolia&lt;/em&gt; can be used as a source of berberine and possible anti inflammatory activity of &lt;em&gt;Tinospora cordifolia&lt;/em&gt; may be attributed to the presence of berberine.&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%">350</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Mohind C.
