ازداد مؤخرا الاهتمام العالمي بالنباتات الطبية المستخدمة في الطب الشعبي باعتبارها مصدراً مهماً للمركبات الطبيعية، ذات الأنشطة البيولوجية المختلفة، ودورها في اكتشاف وتطوير عقاقير جديدة. ومن بين النباتات الطبية المستخدمة في الطب الشعبي في سوريا نبات Centaurium pulchellum، والمعروف محلياً باسم المرار. جمعت الأجزاء الهوائية لنبات المرار من منطقة جبلية في محافظة اللاذقية-سوريا، وتم الحصول على الزيت العطري باستخدام جهاز كليفنجر بمردود بلغ (0.88%)، وقد نتج عن تحليل الزيت العطري المتحصل عليه من خلال تقانة GC-MS، تحديد (75) مركب تمثل (99.56%) من إجمالي الزيت، وكانت المركبات الرئيسية المحددة في الزيت العطري: β-Damascenone (13.18%)، Ledol (10.73%)، Hexahydrofarnesyl acetone (8.42%)، (E)-Verbenol (6.37%).
Recently, global interest in medicinal plants used in folk medicine has increased as an important source of natural molecules with different biological activities and their role in discovering and developing new drugs. Among the medicinal plants used in folk medicine in Syria is Centaurium pulchellum, known locally as " AL-Marar ". The aerial parts of the plant were collected from a mountainous area in Latakia Province, Syria

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 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%.
Chemical composition of the essential oil of the aerial parts of Artemisia
vulgaris L. (Asteracea), grown in Syria was determined by GC/MS. The oil
obtained by hydrodistillation, was found to contain 55 components, accounting
for 98.82 %.
The research aims to study the effect of five harvesting wed (vegetative growth, the
beginning of open inflorescences flowering, the beginning of flowering, full bloom, and
completeness of the vegetative growth at the beginning of the month of Sept
ember and that
of plants that have already cutted), some of the morphological and productivity indicators
for common thyme Thymus vulgaris L . Experiment was designed by the complete
randomized manner in three replicates. Statistical analysis was performed by Anova test
using Genestat and account teams less moral LSD at a significance level of 5%. Results
showed superiority date mower fifth morally on the rest of the dates in terms of index
number of branches (16.50 branch / plant), productivity of the wet weight (55.00 g / plant),
productivity of dry matter (27.08 g / plant), while the superiority of the date of the second
mowing morally the rest of the appointments in terms of the percentage of essential oils
(size / weight) (2.10%), also reached the top of the plant at the time of his high mowing
fourth (21.50 cm).
Highlights the importance of the results by identifying the optimal harvesting date to
get the most fresh and dry weight of material and the highest percentage of essential oil,
and the resulting economic return to the farmer healthy and beneficial to the consumer,
with the continued preservation of the existence of the plant and its tender.
The aim of this study is to determine the essential oil of Ocimum and to find out
the chemical constituents of essential oils of Yemeni Ocimum basilicum Lamiaceae.
