The study of essential oil's ingredients of Ocimum Basilicum (Basil) herb leaves and it's anti-bacterial effects

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%.

Study the essential oil extracted from the bearberry effect on the bacteria Staphylococcus aureus and escerehia coli

In August 2015 the collected leaf of Arctostaphylos uva-ursi were gathered. Then the volatile oil from fresh samples was extracted with n-hexane and other samples with steam distillation.

Pharmacognostic study of Melissa officinalis

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.
