مقال فى مجلة

The essential oil obtained from aerial parts of Myrtus communis grown in the central part of Saudi Arabia was
analyzed by gas chromatography-based techniques (GC–FID, GC–MS, Co–GC, LRI determination, database, and
literature search) using polar as well as non-polar columns, which resulted in the identification of a total of sixty-five
components accounting for 98.2% of the total oil composition. The oil composition was found to be dominated by
monoterpene components accounting for 89.3% of oil composition. Sesquiterpenes (4.8%) and their oxygenated
derivatives (3.5%) were present in lesser amounts. The major compounds of the oil were 1,8-cineole (26.5%), linalool
(18.0%), α-pinene (11.6%), α-terpineol (8.9%), and limonene (4.0%). Other constituents which were present in
appreciable amounts in this oil are trans-geraniol (3.9%), trans-geranyl acetate (3.9%), α-terpenyl acetate (3.3%),
linalyl acetate (2.9%), and δ-cadinene (2.7%).
