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
to investigate the effect of Myrtus communis L ethanolic extract in
streptozotocine-induced diabetic rats.
Single nodes and axillary buds excised from adult trees of Myrtle (Myrtus
communis L.) grown in the field under natural conditions at Damascus
countryside (Ain Elfiegh) were used as primary explants, which were surfacedisinfected
by 70% Ethanol an
d Clorox containing 5.25 % Sodium Hypoclorite
with a drop of Tween 20 for different periods and concentrations before being
placed onto MS basal medium. Established cultures were then transferred onto
MS basal medium containing a combination of growth regulators at different
concentrations (BA at 2.22 and 4.44 μM) each with NAA at 0.54, 1.62, 5.4 μM
or 1.47 μM IBA with GA3 at 0.58 μM for all tratments. Multiplication rate of
12.8-fold was achieved every 4 weeks on MS medium supplemented with 4.44
μM BA with 1.47 μM IBA and GA3 at 0.58 μM.
