This research work was carried out in the nursery field of the Faculty of
AGgriculture in Tishreen Univesity during the spring growing season of 2012, it involved
studying some chemical characteristics of potato tubers of Five newly introduced vari
eties
of potato ( Atlas, Bureen, Bomba, Rumba and Orla), in comparision with Spunta variety as
a control.
It was showed that the hieghest large tuber were recorded in Atlas ,Burren and
Bomba. Bomba variety showed hieghest standards tubers (7.8 Kg/ m2). It was showed also
the hieghest dry matter (DM=20.5 %), and Ash content (1.01%) in tubers, were recorded in
Rumba variety. Bureen and Spunta varieties showed hieghest values of starch contents
(14.5 % and 14.4%) respectively. While Vitamin C (VC ( , was encountered ( 19.36, 17.6,
and 17.6 mg / 100g) for Rumba, Spunta and Bureen respectively. Also, the highest values
for protein content (1%) and the soluble solid (5%) in tubers were found in Rumba
variety.
Cornstarch has been added, with percentages of ( 5%, 10%, 15%,20% and 25%), to
flour beans both types paste (peeled and non-peeled) prepared for the manufacture of a
quick vermicelli preparation (noodles), in order to study the effect of the additi
on of some
chemical and organoleptic characteristics of this product and to determine the ideal
proportion of corn starch added.
The study has shown that there is an inverse relationship between the reduction of
protein content and the increase of the fat percentage and the increase of starch proportion
up to (25%) in both kinds of bean noodles: peeled and unpeeled.
Increasing the ratio of starch above 15% has affected negatively the resulted noodles
colour and some organoleptic characteristics such as taste and smell with the emergence of
a gradual improvement of the appearance of noodles that resulted from flour peeled beans.
Finally , it was found that the best ratio of added starch is 15%.
The aim of this research is to study the effect of sex, age and anatomical location on
the chemical composition and amino acids of Syrian fattened camel meat.
Samples from dorsal rectangular muscle (Longissimus dorsi), and Semimembranous
muscle in
three age groups (1.5 - 2 years, 3 - 4 years and 5 - 6 years) were analyzed
in triplicates from every age group and from each sex.
Percentage of moisture and protein in the flesh of males was higher than the flesh of
females. Moisture and protein decreased, while fat and ash increased according of animal's
age. Moisture, protein and ash were higher in Semimembranous muscle, while fat was low.
The amounts of amino acids were higher in the flesh of males than the flesh of
females, but the amount of methionine was opposite. The amounts of valine, iso-leucine,
methionine, alanine, glutamine, and tyrosine decreased, while The amount of leucine,
threonine, tryptophan, phenylalanine and aspartic increased by animal age. The amounts of
valine, leucine, methionine, alanine, arginine, histidine, glutamine and proline increased
while the quantities of iso-leucine, threonine, tryptophan, phenyl-alanine, aspartic, tyrosine
and glutamine decreased in semimembranous muscle compared with dorsal rectangular
muscle.
تهدف هذه الدراسة إلى التعرف على مواصفات الترب الغضارية لعـدد مـن المواقـع فـي
الجنوب السوري و ذلك من حيث التركيب الكيميائي و الخواص الفيزيائية و الميكانيكية. و مـن
نتائج هذه الدراسة قمنا بتطبيق التصنيفات العالمية للترب الغضارية ( جـداول, منحنيـات,
نماذج رياضية) على ترب المنطقة المدروسة, و من مقارنة النماذج الرياضية العالميـة مـع
نتائج دراستنا المخبرية قمنا باقتراح نموذج رياضي يربط بين طاقة الانتفاخ و قرينة اللدونة،
و آخر يربط بين قرينة الانكماش و طاقة الانتفاخ. و من ثم تحديد موقع هذه التـرب بالنسـبة
للتصنيف العالمي للترب الانتفاخية.
This research have been done at a small local shop for producing Molasses from
raisin (dry grape) located at Maraba village/Al -tall/, Damascus country side. We used
raisin from dried local grape (famous at Damascus country side) which has a high t
otal
carbohydrates contents (up to 30%). Tow methods for producing Molasses: First one
(traditional) and second one (suggested). The results showed that the total
carbohydrates juice of raisin (Al -jalap) in suggested method was more (39.4, 41.3,
42.09%) than in traditional one (38.8, 40.2, 41.2 %), respectively during extraction
process. The Molasses obtained from suggested method was higher in vitamin C 0.32
100Mg/g) and total carbohydrates (93.17 %) comparing with the traditional method
0.22 (100Mg/g) and (88.14 %), respectively. Percentage of ash by suggested method was
2.29 % and by traditional method was 2.1 % so that reflect the highest mineral (k, Ca,
P, and Fe) in the suggested method.

This kind of plant is widely spread in Maroq and it used in common
medicine.
Orange is used in the juice industry, yielding important quantities of by products.
Orange peel is analyzed for chemical composition and water holding capacity. Data show
that, it has high amount of crude fiber, phenolic contents and antioxidant ca
pacity, also it
has high level of water holding capacity. Biscuits are prepared from blendes which contain
a different proportion (5, 10, 15, 20 and 25)% of orange peel flour are also evaluate for
physical and sensory characteristics, chemical composition and rheological properties for
this blendes.
The sensory evaluation does not show any significant difference between control and
that adds with 10% of orange peel flour. Physical parameters, namely, diameter, thickness
and spread ratio were tested. The diameter and thickness of orange peel substituted biscuits
were decreased, whereas spread ratio of biscuits increase with increasing levels of it.
The data reveals that incorporation of orange peel powder in biscuits increase crude
fiber, ash, phenolic contents and antioxidant capacity, it decreases the carbohydrate
content. Rheological properties of the blended flour show increase in water absorption and
stability.
Addition of 40ppm xylanase enzyme reduce the hardness value of the sample in
general, it also decrease the spread ratio as compared to control samples with no enzyme
added.
Sensory evaluation results show good overall acceptability scores for the biscuits
contain 10% orange peel with and without xylanase.
In this work Rosmarinus officinalis L. grown in Syria was studied. The
general characteristics of the whole plant, as well as the leaves and the flowers
were determined. It was shown that there are two varieties of Rosmarinus one
having violet flo
wers and the other having white flowers. The two varieties
were compared morphologically and they were in accord with what was
mentioned in the literature.
The two varieties were also compared chemically and it was possible to
explain the differences mentioned in the literature by differences in the
composition of the volatile oil.
The chemical study of the drug shows the quantity as well as the percentage
of its constituents. At last the main substitute of the drug used in Syria was
shown and compared with the main drug. It was shown that the composition of
the volatile oil of the substitute is different from the composition of the volatile
oil of Rosmarinus, thus it can not be used for the same purpose.
Carob pod is the fruit of the carob tree (Ceratonia siliqua L.). The
fruit and its products, sold both in large stores and local markets,
contribute strongly to the diet of people living in the Mediterranean areas
of Europe.
This study reports th

Homs, Hama and Coast Regions
The chemical content of Cactus grandiflorus L was studied from
amino acids and sugars. The duration of these materials in the
branches and plant flowers was determined and the relative
proportions of these compounds were determined by using the thin
layer chromatography methods(TLC) and the highly efficient liquid
chromatography( HPLC).
