Abstract The essential oils of the fruits of Angelica sylvestris L. var. sylvestris (Umbelliferae) obtained using hydrodistillation (HD), microdistillation (MD) and micro-steam distillationâsolid-phase microextraction (MSD-SPME) techniques were analyzed by GC and GC/MS. The composition of the oils depended on the isolation method employed. α-Pinene (25.6%, 36.2% and 9.2%, respectively), β-phellandrene (9.1%, 9.9% and 3.2%), bornyl acetate (7.3%, 4.3% and 6.9%), limonene (5.6%, 4.3% and 2.1%), myrcene (4.4%, 4.0% and 1.3%), camphene (3.9%, 4.7% and 1.2%), α-chamigrene (3.4%, 4.4% and 9.1%) and β-sesquiphellandrene (2.5%, 3.8% and 8.7%) were found as the main constituents in the oils. p-Cresol (6.5%), epi-α-bisabolol (5.6%), (Z)-β-farnesene (5.5%), naphthalene (4.4%), daucene (3.1%), amorpha-4,11-diene (3.1%) and γ-muurolene (2.5%) were also among the main constituents of the oil isolated by MSD-SPME.
