Chemical Composition of the Essential Oil of the Subterranean Parts of Valeriana alliariifolia

The subterranean parts of Valeriana alliariifolia Adams were subjected to hydrodistillation and traceamount of essential oil was obtained. The chemical composition of the oil was identified by using capillary GasChromatography (GC) and GC/MS simultaneously. In total 68 constituents were identified, representing 87.6 %of the total oil. The essential oil was dominated by isovaleric acid (28.6%), which is followed by -guaiane(7.2%), -humulene (4.7%), hexadecanoic acid (4.3%), valeric acid (3.7%) and humulene epoxide-II (3.6%) asthe major components.
