Chemical composition of the essential oil of the aerial parts of Artemisia
vulgaris L. (Asteracea), grown in Syria was determined by GC/MS. The oil
obtained by hydrodistillation, was found to contain 55 components, accounting
for 98.82 %.
The volatile oil of Anthemis wettsteiniana was studied in
environmentally different regions distributed on five locations in the
provinces of Homs and Hama, in order to determine the quantity and
quality and effect of the surrounding environment,
on the volatile oil
specifications. The plants were gathered during tow phonological
phases of the life of the plant included the vegetative growth stage- the
full of flowering stage. It was then extracted through water extraction
method. It was found that the highest percentage of volatile oil was
recorded in Al-afif location at the full of the flowering stage during
the 2013 season, where the percentage of the volatile oil was 0.12
(ml/100g) ,while the lowest percentage of volatile oil was recorded in
Tal-snan during the 2014 season , the percentage of the volatile oil was
0.04 (ml/100g).
The volatile oil of Anthemis scariosa was studied in environmentally
different regions distributed on five locations in the provinces of Homs and
Hama, in order to determine the quantity and quality and effect of the
surrounding environment, on th
e volatile oil specifications. The plants
were gathered during tow phonological phases of the life of the plant
included the vegetative growth stage- the full of flowering stage. It was
then extracted through water extraction method. It was found that the
highest percentage of volatile oil was recorded in Al-hamra location
at the full of the flowering stage during the 2013 season.
Chemical composition of the essential oil extracted by hydrodistillation (Clevenger
apparatus) from some aerial parts (ripe and unripe fruit) of Pistacia Atlantica
(Anacardiaceae) which are widely spread throughout the countries of the Mediterranea
n
Sea and have been occupying a good part of the mount of Syria was determined by Gas
Chromatography-Mass Spectrometer GC/MS.
The results of analyzing showed that the oil consist of five compounds in ripe and
unripe fruit, and it was found that the component with the highest ratio in both samples is
the same 2-methylbutanal and its ratio 95.713% in the ripe fruit and 94.138% in the unripe
fruit.
The results of this study also show that the essential oil components of the Syrian
Pistacia fruits are completely different from those in different environments due to the
different types of pistacia species which have been studied and the different environmental
conditions in which this plant grows.
