تم جني المجموع الخضري الهوائي لنبات الشمرة Fennel في شهر ايلول من عام 2014 في منطقة مصياف. استخلص الزيت العطري بالنقع بالهكسان النظامي و عينة أخرى طازجة بالجرف ببخار الماء , و تبين ان نسبة الزيت العطري يساوي 3% من وزن العينة الاولى , و 3.4 % من وزن العينة الثانية.
In September 2014 the collected air-green samples of Fennel herb were gathered. Then the volatile oil from fresh samples was extracted with N-hexane and other samples with steam distilled water.

In October 2014, the collected air-green samples of Basil herb were gathered from the region of MashtaAlhulu in the ,Then the volatile oil from fresh samples was extracted with N-Hexane and other samples with steam distilled water, and we have found
the percentage of the volatile oil in the first sample (N-Hexane) is 2,7% , and 2,5% in the second sample (steam distilled water). Suitable conditions were chosen to separate the components of the volatile oil by GC-MS and we noticed : - the first sample (extracted with N-hexane) contain 18 compounds, and they are: Six Terpenes compounds and they form 21.22%,Hydrocarbon compounds form 21.8% from the total weight and they are 7 compounds, and one compound from Ketone class dicycle and its percentage is 2.32%,and two Ester compound and they form 18.96%, One phenolic compound and forms 21.60%, one Ether compound and forms 14.08%. -the volatile oil from the second sample (extracted with steam distilled water) contains 11 compounds, and they are: 6 compounds belong to Hydrocarbon class and they are the main components in the volatile oil with a 91.24% of the oil total weight, One compoundfrom Ether class forms 1.62%, one phenolic compound which forms 3.93%, and three Terpenes compounds and they form 3.17%.
Information extraction is the task of finding structured information
from unstructured or semi-structured text. It is an important task in
text mining and has been extensively studied in various research
communities including natural language proc
essing, information
retrieval and Web mining. It has a wide range of applications in
domains such as biomedical literature mining and business
intelligence. Two fundamental tasks of information extraction are
named entity recognition and relation extraction. The former refers to
finding names of entities such as people, organizations and
locations. The latter refers to finding the semantic relations between
entities.
Phenols were studied in the leaves of Syrian olive varieties collected from (Harasta
and Ghouta, Damascus Countryside and Qalamun). Phenolic compounds were extracted
from the olive leaf varieties after disposal of plant pigments and fatty compounds, and
total phenols separated with solvent (methanol - water).
The study suggests a new approach to segment the ultrasound
uterus images to obtain the fetus region. The approach consists of
three stages. The first includes the preprocessing in which the
speckle noise is removed from the ultrasound images depe
nding on
sequential filtering of Gabor filter and median filter. Second, an
improved active shape contour independent of edges is applied to
segment the uterus images. The last stage is the post processing
which depends on the morphological operation to eliminate the
undesired region and obtain the region of interest (fetus).
The designed system has been tested by means of medical database
of ultrasound uterus images downloaded from the ULTRASCAN
CENTRE site in Kaloor (India). The experimental tests show that
the proposed sequential filtering technique improves the active
shape contour algorithm performance significantly, so the system
segment the uterus images correctly even in the presence of speckle
noise.
The main properties(yield of juice, total soluble solid, pH, total acidity, total
sugars), some antioxisant compounds as (vitamin C, carotenoids, total phenol,
anthocyanins), and antioxidant activity measured by DPPH method for some
main Syrian or
ange cultivars (navel, valancia, blood orange, and shamouti)
were investigated. The results showed that valancia was the highest in juice
yield (55.16%), while navel had the highest content of carotenoids(8.68mg/100g)
and the lowest one of vitamin C(31.53mg/100g). Whereas, blood orange was
superior in its content of total phenolic (295.73 mg gallic acid100/g) and
antioxidant activity, (74.833%) among the studied cultivars.
