Abstract

Volatile oils from the aerial parts, flowers and roots of an endemic species Ferulago blancheana Post, were obtained by hydrodistillation and analyzed by GC and GC/MS. Main components were found to be bornyl acetate (11.7%) and ß-caryopyllene (10.2%); sabinene (23.2%), myrcene (17.5%); (E)-2-decenal (20.3%), caryopyllene oxide (17.8%) for the aerial parts, flowers and roots, respectively. Antimicrobial activity study with bioautography method was performed against three different microorganisms; Pseudomonas aeruginosa ATCC 13388, Escherichia coli NRRL, Staphylococcus aureus ATCC BAA 1026, and Candida albicans ATCC 24433. The results showed that essential oils obtained from the aerial parts, flowers and roots were active against S. aureus and C. albicans, however essential oils obtained from the aerial parts and roots were found to be less effective against S.aureus. In addition, no antibacterial effects were observed against P. aeruginosa
