C.&lt;em&gt; Rhizomes&lt;/em&gt; and evaluation of antimicrobial activity.&lt;strong&gt; Method:&lt;/strong&gt; The essential oil was collected by hydro distillation and analyzed by Gas Chromatography (GC) and Gas Chromatography-Mass Spectroscopy (GC- MS). Volatile oil constituents, antimicrobial potential of&lt;em&gt; Nardostachys jatamansi&lt;/em&gt; D. C. &lt;em&gt;Rhizomes&lt;/em&gt; have been studied using different concentrations of the volatile oil against some micro-organisms. &lt;strong&gt;Results:&lt;/strong&gt; A total of 10 compounds were identified from their fragmentation pattern. The Identified compounds were Calarene (20.4%), Vardiflorene (12.3%), &amp;alpha;- Panasinsen (9.7%), &amp;alpha;- Santalene (4.6%), &amp;gamma;-Himachelene (17.1%), Jatamansone (7%), Ionol 4 (9.9%), 2,2,7,7- Tetramethyl tricyclo[6,2,1,0 (1,6)] undec-4-ene 3-one (1.7%), Epiglobulol (1.9%) and Resibufogenin (8.4%). Among them major constituents characterized was Calarene (20.4 %) and followed by &amp;gamma;-Himachelene (17.1%) and Vardiflorene (12.3 %). The volatile oil showed significant activity against all tested microorganisms. The maximum antibacterial activity was shown with 1%v/v of volatile oil on &lt;em&gt;Staphylococcus&lt;/em&gt; aureus (12.8 mm) followed by &lt;em&gt;Escherichia coli&lt;/em&gt; (12.4 mm), whereas maximum anti-fungal activity was shown by 1% v/v of volatile oil on &lt;em&gt;Candida albicans&lt;/em&gt; (12.3 mm) followed by &lt;em&gt;Aspergillus niger&lt;/em&gt; (11.9 mm). &lt;strong&gt;Conclusion:&lt;/strong&gt; All identified constituents showed antibacterial activity and antifungal activity. Thus, the constituents should be further identified and analyzed by other spectrosopical techniques.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">2</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">230</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Vijender Singh&lt;sup&gt;1&lt;/sup&gt;, Neha Rana*&lt;sup&gt;2&lt;/sup&gt; , Mohd Ali &lt;sup&gt;1 &lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
