title: GC/MS Analysis of the Essential Oil of Vernonia cinerea.
abstract: The hydro-distilled essential oil obtained from the roots of V. cinerea Less. (Asteraceae) was investigated by gas chromatography equipped with flame ionization detector (GC-FID) and gas chromatography coupled with mass spectrometry (GC/MS). Twenty-five constituents were identified, which represented 97.4% of the total oil. The major compounds were α-muurolene (30.7%), β-caryophyllene (9.6%), α-selinene (8.7%), cyperene (6.7%) and α-gurjunene (6.5%). The essential oil was dominated by sesquiterpene hydrocarbons (87.8%).
