شجرة البطم الفلسطيني (pistacia palaestina) من الأنواع المتوطنة في منطقة الحوض البحر الابيض المتوسط و منها سوريا . و هي تنتشر بشكل اساسي في غابات السنديان العادي و الصنوبر البروتي , و تحت ظروف التدهور المتعددة التي تتعرض لها المناطق الحراجية في الطابق البيو مناخي الرطب و شبه رطب تتسارع تحول ما تبقى من تكوينات غابوية الى ماكي .
Pistacia palaestina is one of endemic species woodlands in mediterraneans areas and Syria , Wich is spreading principally in Quercus ssp and pinus ssp comminuties. Those communities of woodlands are suffered by multiple conditions as deforestation , so these woodlands are accelerated to developing toward surbland (maquis).

Chemical composition of the essential oil extracted by hydrodistillation (Clevenger
apparatus) from some aerial parts (ripe and unripe fruit) of Pistacia Atlantica
(Anacardiaceae) which are widely spread throughout the countries of the Mediterranea
n
Sea and have been occupying a good part of the mount of Syria was determined by Gas
Chromatography-Mass Spectrometer GC/MS.
The results of analyzing showed that the oil consist of five compounds in ripe and
unripe fruit, and it was found that the component with the highest ratio in both samples is
the same 2-methylbutanal and its ratio 95.713% in the ripe fruit and 94.138% in the unripe
fruit.
The results of this study also show that the essential oil components of the Syrian
Pistacia fruits are completely different from those in different environments due to the
different types of pistacia species which have been studied and the different environmental
conditions in which this plant grows.
The refered data from geophysical surveys (seismic-logging)
and samples analysis,that the paleozoic Tanf/Al Aba
formation that belong to Paleozoic Era ,represent the most
important rock generating hydrocarbon in Syria. And this
covers big parts o
f Syria and with different thickness, between
zero to 1100 m.
This research was aimed at evaluation of growth and productivity of two
pine species; namely, Maritime Pine Pinus pinaster Sol. and Brutia Pine P.
brutia Ten. at the Cool-Humid Bioclimate Zone in the Mid Altitudes of the
Coastal Mountain Ranges. T
he study revealed that, height growth was not
significant between the two species. Although average diameter at breast
height was significantly superior in Brutia pine to that of Maritime pine, this
was not reflected on productivity of trees, wood volume, or the annual growth
rate due to great differences in growth forms of the two species.
The choloroformic extract of Pistacia Lentiscus L. is separated and
resulted in the isolation of one compound Abietadiene.
The structure of the compound was detrmained by spectroscopic
technique :
[ IR,1H-NMR,13C-NMR, DEPT(90º) , DEPT(135º), HMQC
,
HETCOR, 1H-1H COSY, HMBC, Mass. ]
Al Rutba Formation , bellowing to the upper Cretaceous, is one the
main formation of the stratigraphical coumn of Euphrate Depression.
It is importance becomes from that it can statute the principle
petroleum reservoir in high member of the depres
sion fields.
Producing oil and the natural gas.
The importance of this group is to be the main reservoir of oil in
various fields of low oil producing natural gas. The present study is
based on subsurface geological data, presented by cores, well logs and
chemical results of the analyses laboratory.
