Study on the effect of the extracted volatile oil of zizuphus jujuba leaves on Staphylococcus Aures and Escershia Coli bacteria Dr.Emmad AL-Haddad

ABSTRACT
In September-october 2014 the collected air green samples of
zizuphus jujuba was extracted. Suitable conditions were chosen to
separate the components of the volatile oil from Gs/Ms and we noticed the following:
– 16 compounds were found in the extracted volatile oil of the
extraction by petrolium ether, the main compound is palmetoleic acid ,
it form 29.13% of the volatile oil weight, and palmitic acid, it form
15.5%.
Also volatile oil was extracted from fresh leaves by steam
distillation contains 24 compounds, the main compound is Oleamid. It
forms 23.30% of the volatile oil weight. Also, volatile of the extraction
from dry leaves by n-hexane contain 8 compounds, the main
compound is the Squalene (a triterpeen compound), it from 72.83% of
the volatile oil weight and the volatile oil of the extraction from fresh
leaves by n-hexane contain 15 compounds, the main compound is
Alpha (α) tocopherol of (vit E), it from 38.83% of the volatile oil
weight, We found the volatile oil extracted from leaves of zizuphus
jujuba active agnist the Staphylococcus Aures and Escershia Coli
bacteria.
