Composition of the essential oils of Angelica sylvestris L. var. sylvestris isolated from the fruits by different isolation techniques

Abstract

The essential oils of the fruits of Angelica sylvestris L.var.sylvestris (Umbelliferae) obtained using hydrodistillation (HD), nucrodistillation (MD) and micro-steam distillation-solid-phase microextraction (MSD-SPME) techniques were analyzed by GC and GUMS. The composition of the oils depended on the isolation method employed. alpha-Pinene (25.6%,36.2% and 9.2%, respectively), beta-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%), alpha-chamigrene (3.4%,4.4% and 9.1%) and beta-sesquiphellandrene (2.5%,3.8% and 8.7%) were found as the main constituents in the oils. p-Cresol (6.5%), epi-alpha-bisabolol (5.6%), (Z)-beta-farnesene (5.5%), naphthalene (4.4%), daucene (3.1%), amorpha-4,11-diene (3.1%) and gamma-muurolene (2.5%) were also among the main constituents of the oil isolated by MSD-SPME.
