جمعت عينات رسوبية من الطبقة السطحية من الحوض المائي لنهر سانت جونز فلوريدا و جرى استخلاصها و دراستها كميًا و نوعيًا عن طريق تقانة الكروماتوغرافيا الغازية GC-MS و GC-FID بهدف التعرف على الفحوم الهيدروجينية الأليفاتية (AH) و أقرانها، و مركبات الدلائل الحيوية المتواجدة فيها. تتميز هذه الرسوبيات بمحتوى مرتفع من المواد العضوية (TOM) إذ تشكل الفحوم الهيدروجينية فيها ما نسبته ٢,٧-٣,٥ % من إجمالي المواد العضوية المتوفرة فيها.
Samples of surface sediment of St. Johns River Basin were collected, extracted and their aliphatic hydrocarbons (AH) were determinated quantitatively and qualitatively by GC-FID and GC-MS Techniques, were used to characterize the (AH) hydrocarbons homologous and biomarker compounds.The sediments contained high organic matter content, while the hydrocarbons AH represented ٠,٣٥-٢,٧٢٪ of the total organic matter (TOM) found in sediments.

Neem (Azadirachta indica A. Juss.) is an important tree species that is known to posses anthelmintic, contraceptive, antimicrobial, antidiabetic and sedative properties. Therefore, the present study aimed to identify various compounds present in the
leaf extract of neem and to enlist various biological activities of these compounds through literature survey. Methodology: Extract of neem was obtained by soaking 100 g dry powdered leaves in 1000 mL methanol followed by filtration. This was successively fractioned using n-hexane and chloroform. Results: GC-MS analysis of the chloroform fraction was performed and 7 compounds namely 2-pentanol, acetate (9.72%); decane (8.96%); 11-oxa-dispiro[4.0.4.1]undecan-1-ol (6.56%); nonanoic acid, 9-(3-hexenylidenecyclopropylidene)-, 2-hydroxy-1-(hydroxymethyl)ethyl ester, (Z,Z,Z)- (7.13%); quinoline-4-carboxamide, 2-phenyl-N-n-octyl- (9.79%); nonacosane (44.27%) and tetratriacontane (13.43%) were identified. Conclusion: Literature survey showed that the identified compounds possessed antibacterial, antifungal, anticancer, cytotoxic, anti-inflammatory, antioxidant, and antiviral properties.
The extracted oil from Gundelia Tournefortii seeds, which belongs to Asteraceae
family and which is known as one of the medical herbal plants that is widely spread in the
Syrian environment, was isolated using soxhlet continuous extraction. It's ch
emical
composition was determined by GC/MS (Gas Chromatography – Mass Spectrometry). The
analysis led to identification of 20 components. The extracted oil was characterized by
high content of Linoleic Acid (52.9%), Palmitic Acid (20.1%) and Squalene (10.1%).
The mass spectra of 5 trisubstituted aromatic compounds were studied. The
spectra were recorded by local GC-MS at 70 eV and compared with
bibliographic spectra. The spectra of each compound were different. The using
of local GC-MS for identificati
on required recording the spectra references at
the same conditions.
Due to the economical and medical importance of the Capparisspinosa plant and the
wide distribution of this plant in the Syria environment, it was thought that a study of the
composition of Essential Oil extracted from this plant.
The Capparisspin
osa Essential Oil was extracted and purified components wher
studied by GC-Mass spectrometry.
The Oil was obtained by steam distillation (Clevegerexractor) and by solvent n-
Hexane. Components have been found which was about (98.9 %) from the total of
essential oil.
The major components were determined by steam distillation which were the
following:Palmitic acid (21.12%), Hexatriacontane (15.87%), n-Heneicosane (10.96%),
Pentatriacontane (9.92%), Hexahydrofarnesyl acetone (8.51%).
The major components were determined by solvent Hexane: Isobornyl acrylate
(66.89%), 2-Azido-2,3,3-trimethylbutane (6.09%), Ethanolamine (5.41%).
In the present work, batch electrocoagulation experiments were carried out
to evaluate the removal of polycyclic aromatic hydrocarbon (PAHs) from water
using aluminum electrodes. The effects of initial pH, current density,
electrolysis time, initi
al concentration of PAHs, electrolyte type, and electrolyte
concentration were investigated to achieve the optimal removal efficiency. The
results indicated that the electrocoagulation utilizing the aluminum, as anode
and cathode, was an efficient tool in the reduction of these contaminants. The
treatment process was found to be largely affected by the current density and
the initial composition of water. The removal rate was significantly increased
using NaCl as an electrolyte where indirect oxidation by hypochlorite forming
later during the treatment was occurred. The results demonstrated that the
technical feasibility of the electrocoagulation as a possible and reliable
technique for the treatment of PAHs contaminants in water.
