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 by the components of the
volatile oil by Gs/Ms and we noticed.
- 16 compoun
ds 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 of the extracted from fresh leaves by steam
distillation contain 24 compounds, the main compound is Oleamid ,it
from 23.30% of the volatile oil weight.
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.
