Angelica sylvestris L. (Apiaceae) of the Isle of Skye (Scotland): chemical composition of essential oil from the aerial flowering parts

Abstract

Angelica is a large genus of plants belonging to the Apiaceae family that includes about 100 species of biennial or perennial herbs. Several species of this genus are extensively used in various traditional medicines and, despite their content in toxic furanocoumarins, also as food. In this study, the chemical composition of the essential oil (EO) from aerial flowering parts of Angelica sylvestris L., a plant distributed in Europe, North and Central Asia, collected in the Isle of Skey (Scotland), was analyzed by GC and GC-MS. No one report has been previously published on this accession. The result showed the presence of a large quantity of monoterpene hydrocarbons with limonene (51.89%), by far, as the most abundant component. Other metabolites present in lesser quantity were β-pinene (4.61%), α-pinene (3.54%), and thymol (3.33%). Considerations with respect to all the other EOs of A. sylvestris taxa, studied so far, were carried out.
