Abstract

The aim of the present study was to analyzed chemical constituents of the essential oil, obtained by hydro distillation of the roots of Crassocephalum crepidi -oides (Benth.) S. Moore. The oil was analyzed using gas chromatography equipped with flame ionization detector (GC-FID) and gas chromatography coupled with mass spectrometry (GC/MS). Forty-seven compounds were identified, representing 93.2 % of the total oil. The main constituents were ( E )-β-farnesene (30.6%), α-humulene (10.3%), β-caryophyllene (7.2%), cis -β-guaiene (6.1%) and α-bulnesene (5.3%). The oil was constituted mainly of sesquiterpene hydrocarbons (77.6%), followed by oxygenated sesquiterpenes (8.7%), oxygenated monoterpene s (3.5%), monoterpene hydrocarbons (2.8%) and phenyl derivatives (0.6%). This is the first report on the essential oil composition of the roots of C. crepidioides . Keywords: Crassocephalum crepidioides (Benth.) S. Moore, Essential oil composition, ( E )-β-Farnesene, GC/MS. INTRODUCTION
