تم جني الأوراق لنبات المليسة Melissa Officinalis في شهر تشرين الأول من عام 2014 في محافظة حمص. استخلص الزيت العطري من الأوراق الطازجة بطريقتين, العينة الأولى بالنقع بالهكسان النظامي و عينة أخرى بطريقة الجرف ببخار الماء , و تبين ان نسبة الزيت العطري يساوي 2,7 % من وزن العينة الاولى , و 2,4 % من وزن العينة الثانية, تم اختيار شروط مناسبة لفصل مكونات الزيت العطري على جهاز ال GC/MS و تبين: أن الزيت العطري المستخلص بالنقع بالهكسان النظامي يحوي على 25 مركب, المركبين الرئيسين هما ألفا سيترال و بيتا سيترال و يشكلان نسبة 52,03 % و هما مركبين ألدهيدين , كما تشكل المركبات التربينية نسبة عالية و هي 44,88 %, و هذه المركبات إما غولية حلقية أو غولية ثنائية التربين أو من زمرة السيسكي تربينات , كما وجد مركبين من طبيعة استرية بنسبة 2,12 % و مركب حمضي بنسبة 0,97%.
In October 2014 the collected air-green samples of melissa officinalis were gathered. Then the volatile oil from fresh samples was extracted with N-hexane and other samples with steam distillation. Suitable conditions were chosen to separate the components of the volatile oil by GC-MAS and we noticed : (25) compounds were found in the extracted volatile oil of the first sample ( extraction by N-hexane ). 3 compounds of them are alcohol noncyclic MonoTerpine class and they form 3,46% of the volatile oil weight, 1 alcohol cyclic Monoterpine compound forms 1,83% of the volatile oil total weight, 1 compound from cyclic DeTerpine class and it forms 2.31%, 2 compounds from cyclic MonoTerpine class and they form 3,14%, 2 compounds from Aldyhol group which form 52.03% from the volatile oil's weight. 13 compounds from SesquieTerpine class with a 35,14% of the total weight, 2 Ester compounds and they form 2,12%, and 1 acetic compound which is Lenolenic acid with a 0,97% form the volatile oil total weight.

The antimicrobial activity of aqueous extract of Zingiber Officinalis
were tested for their antifungal activity against the following
dermatophytes :Candida albicans, Cladosporium cladosporiosis ,
Cryptococcus neuphormans, Trichophyton violaceum a
nd against
other four bacteria : E. coli, Pseudomonas aeruginosa.
Staphylococcus aureus, Streptococcus pyogenes. The extract used in
traditional medicine for the treatment of nausea was tested in vitro
through the Agar Disk Diffusion Method. The minimum inhibitory
concentration (MIC) of extracts determined by the Agar dilution
method ranged from 1.5 to 12.5 mcg. The most sensitive
microorganisms to the extract were Candida albicans with MIC 1.5
and E coli with MIC 1.5 mcg.
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.

The relaxant effect of ethanolic extract of Pelargonium odoratissimum was
studied on both spontaneous and Noradrenaline-induced contraction of isolated strips prepared from
rabbit portal vein.
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%.
