Some of the traditional herbal formulations contain &lt;em&gt;Plumbago zeylanica &lt;/em&gt;L, (commonly known as Chitraka or Chitramoolam) to treat various disorders for centuries in Africa and Asia. &lt;strong&gt;Methods:&lt;/strong&gt; The quantity of Plumbagin was detected in different tissues of &lt;em&gt;P. zeylanica&lt;/em&gt; through HPTLC analysis. We evaluated and compared the alcoholic tissue extracts of leaf, stem and root of &lt;em&gt;P. zeylanica&lt;/em&gt; with standard pure Plumbagin for its &lt;em&gt;in vitro&lt;/em&gt; cytotoxic effects (metabolic viability; MTT assay) in A549 Lung cancer cells and antioxidant potential (DPPH free radical scavenging and total phenol content). RNA sequencing and transcriptome analysis was performed in the most potent tissues of &lt;em&gt;P. zeylanica&lt;/em&gt; demonstrating efficient pharmacological activity. &lt;strong&gt;Results:&lt;/strong&gt; The root extract containing 1.3% of plumbagin exhibited strongest scavenging potential with 50% radical scavenging (IC&lt;sub&gt;50&amp;nbsp;&lt;/sub&gt;value of 3.99 &lt;em&gt;&amp;mu;&lt;/em&gt;g) in comparison with 35.85 &lt;em&gt;&amp;mu;&lt;/em&gt;g in stem (0.2% Plumbagin) and 18.06 &lt;em&gt;&amp;mu;&lt;/em&gt;g in leaf with 0.00007% Plumbagin. The &lt;em&gt;in vitro&lt;/em&gt; cytotoxicity in A549 cells also showed that the root extract was most potent with an IC&lt;sub&gt;50&amp;nbsp;&lt;/sub&gt;value of 164.5&amp;nbsp;&lt;em&gt;&amp;mu;&lt;/em&gt;g as compared to extracts from stem (IC&lt;sub&gt;50&lt;/sub&gt;= 379.5&amp;mu;g) and leaf (IC50= 274.9 &lt;em&gt;&amp;mu;&lt;/em&gt;g). &lt;strong&gt;Conclusion:&lt;/strong&gt; The strong antioxidant potential shown by the &lt;em&gt;P. zeylanica &lt;/em&gt;extract demonstrates its ability to protect the non-target (normal) cells against oxidative stress, while the cytotoxic effects suggest that it could inhibit the growth of cancerous cells. Further, transcriptome analysis predicted the expression of potent gene transcripts coding for quinone biosynthesis in the root tissues of &lt;em&gt;P. zeylanica.&lt;/em&gt;&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">706</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Balachandran Karpaga Raja Sundari&lt;sup&gt;1*&lt;/sup&gt;, Srivani Telapolu&lt;sup&gt;2&lt;/sup&gt;, Bilikere S.
