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

Abstract

The subterranean parts of Valeriana alliariifolia Adams were subjected to hydrodistillation and trace amount of essential oil was obtained. The chemical composition of the oil was identified by using capillary Gas Chromatography (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 delta-guaiane (7.2%), alpha-humulene (4.7%), hexadecanoic acid (4.3%), valeric acid (3.7%) and humulene epoxide-II (3.6%) as the major components.
