has many ،The aerial part of Lavandula stoecha L. family Lamiaceae
moreover ، asthma and digestive diseases،important effects against cold
anxiety and hypertension. These ،it has effects in treatment of dermatitis
effects are turning back to the c
ontent of its essential oil.
This kind of plant is widely spread in Maroq and it used in common
medicine.
A morphological , anatomical and chemical study was carried out on Salvia viridis
L. (Lamiaceae) . The results showed presence of two types of trichomes :
- Glandular hairs with four or eight celled globular heads or with oval heads .
- Eglandular
hairs which are unicellular or multicellular , in addition to presence of
candle shaped eglandular hairs .
The palynological study revealed that the pollen grains were prolate and they had six
germination lines , exine appeared reticulate .
The extraction of volatile oils have been done by dry evaporation using GC/MS
technique , chromatographic analysis of these extracts have showed the presence of
complex of carboxylic acids , hydrocarbons , terpenes , esters and aldehydes .
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%.
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%).
The seeds of Syrian cumin and Brown mustard used for human
nutrition were analyzed in this study to determine some of their
major chemical constituents and minerals.
The results showed that the contents of cumin and mustard seeds
were protein , l
ipids,
phospholipids , ash respectively.
Mineral contents were phosphorus, ,calcium , Magnesium , potassium , and iron for cumin and
mustard seeds respectively.
