Abstract The essential oils obtained by hydrodistillation of the stem and root of Ferula galbaniflua were investigated by GC and GC/MS. Forty-one components were identified in the stem oil, and 34 components in the root oil, representing 87.4% and 86.1% of their total oils, respectively. Î²-Pinene was the major component in both oils: stem (46.4%) and root (58.8%). The other main constituents in the stem oil were cis-chrysanthenyl acetate (6.1%) and (E)-nerolidol (5.2%).
