The aim of current research was to study some diagnostic characteristics
/morphological, physical, chemical/and the origin structureofforest soils in Syrian coastal
region. In addition to estimation of microbial activity of some microbial groups/ba
cteria,
fungi, actinomycete/ to establish a general view of these soils.
Two complete sections were prepared in the considered soils /Safita-Tartous/
andsamples were taken after the soils sections description for diagnostic characterization.
The results showed that the soil pH was between neutral and tiny basic and because
of the richnessof the studied soil by calcium carbonate. However, the highest percentage of
organic matter in all sections were concentrated in the surface horizon and was decreasing
with depth. Our results also showed that the microbial activity was positively correlated
with the content of the organic matter and negatively with the depth, so the total number of
bacteria and fungi was decreasing in the under surface horizon. A
muddymetamorphosedhorizon (Bm) was formed in the two sections.
Due to the economical and medical importance of the Melilotus plant and the wide
distribution of this plant in the Syria environment, it was of necessity to study the the
composition of organic matter extracted from the leaves of this plant.
The M
elilotus Officinal organic matter was extracted and purified their where were studied
by GC-Maas spectrometry.
The organic matter was obtained by Soxhlet extractor and by solvent n-Hexane.
Components have been found which was about (99.91%) from the total of Essential Oil.
The major components were extracted by Soxhlet extractor and the following components
were determined : n-Docosane(39.82%) , Hydrocoumarin(15.39%) ,
Methyl 3-(2-hydroxyphenyl)propionate(14.29%).
The major components were determined by solvent n-Hexane:
1,2-Benzenedicarboxylic acid(17.77%) , 9,12,15-octadecatrienoic acid(12.85%)
The effects of the extracted aromatic oil from the leaves of Melilotus plant on some of
Pathogenic Microorganisms were studied.
