This research was carried out to determine the quantity of essential oil extracted
from myrtle Myrtus communis L leaves, by hydro distillation, and to identify the
major and minor components, besides to determine its quantities in the essential oil
by Gas Chromatography-Mass Spectrometry GC-MS. The samples were collected
on November 2013 from eight different climatic locations (Aleppo, Zarzour, Alzenea,
Katra AL-Rayhan, Al- Rayhana, Kasab, Mashta al-Holou and Mosiaf). The
quantity and composition of the essential oil were estimated on the basis of the
leaves dry weight. Oil quantity varied between the studied genotypes from different
locations, which range from 0.46 to 0.55 ml, with non-significant differences.
Eighteen compounds were identified in myrtle essential oil, and there were
significant differences in 13 compounds. 1,8-Cineole performed the highest rate
(18.85%) compared with other components, followed by α-Pinene (16.93%). While
the lowest percentage was (0.31%) of Myrcene. The
