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 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. ]
143 stool samples were examined, they were taken from people
living in Alqalamoun region, in Syria.
The aim of this study was to determine the species of enteric
parasites and their prevalence. The percentage of the prevalence of intestinal parasi
te infections in the stool samples was 17.48 %. The species of enteric parasite according to their prevalence were: Entamoeba coli (6.29%), Giardia lamblia (4.89%), Entamoeba histolytica(2.09%), Taenia saginata and Ascaris lumbricoides(1.39%), Enterobius vermicularis and Iodamoeba buetschlii (0.69%), Whereas the percentage of the prevalence of Blastocystis hominis was (6.29%),and Candida sp. Was (7.69%).
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).
