The inhibition of violacein production in &lt;em&gt;Chromobacterium violaceum&lt;/em&gt; (ATCC 07) was assayed as anti-quorum sensing activity using micro-dilution method. The molecular docking of the GC-MS ligands and penicillin‑binding protein 2x (PDP2) and CviR was executed using AutoDock Vina. &lt;strong&gt;Results: &lt;/strong&gt;The two volatile compounds namely phytol (93.58%) and 3-tetradecyn-1-ol (6.42%) were shown by GC-MS. The extract exhibited antibacterial activity against the selected bacterial strains with minimum inhibitory concentration (MIC) values ranging from 1.56 to 3.125 mg/mL. The maximum inhibition of violacein production of 53.93% was observed at 1.56 mg/mL. Both compounds had docking scores of more than -6.0 kcal/mol against the target proteins. &lt;strong&gt;Conclusion: &lt;/strong&gt;The results revealed that the extract is a potential source of antibacterial and anti-quorum sensing compounds and thus can have pharmacological applicability.&lt;/p&gt;
