Abstract
Abies cephalonica Loudon consists one of the three fir species occurring
in Greece. The aim of this study was to evaluate the chemical
composition of the essential oil (EO) from needles of A. cephalonica
from Mt. Aenos (Kefalonia Island, Greece) and to investigate its
antimicrobial activity. The EO was obtained by hydrodistillation and 68
constituents corresponding to 99.4% of the EO were identified by using
GC-MS analysis. The major chemical category of the volatile compounds
were the monoterpene hydrocarbons (63.9%), followed by oxygenated
monoterpenes (20.2%). In particular, the main components were
beta-pinene (26.9%), bornyl acetate (12.5%), alpha-pinene (10.1%),
camphene (9.2%), limonene (8.1%), gamma-eudesmol (8.1%) and
beta-phellandrene (5.8%). To the best of our knowledge, the present
study is the first research, reporting the phytochemical profile and the
antimicrobial potential of the EO of A. cephalonica from this distinct
geographic area
