تم التحديد النوعي و الكمي لمكونات الزيت العطري الطيار لبذور الكمون باستخدام تقانة الكروماتوغرافية الغازية بالمقارنة مع مركبات عيارية, حيث تم حساب النسبة المئوية لكل من بينين و سايمن و ألدهيد الكمون. تمت دراسة تأثير العوامل المختلفة على محتوى زيت بذور الكمون و ذلك من خلال تتبع التغيرات الكمية التي تطرأ على نسبة كل من الزيت الكلي و الزيت العطري الطيار و بعض المكونات الرئيسية للزيت العطري الطيار.
The identification of the cumin oil composition was determined qualitatively and quantitatively by GC, using standard compounds. The components of the cumin seed oil (Cuminaldehyde, p-cymen and β-penine) were matched with the standard compounds. The factors effect on some components of cumin seed volatile oil were studied. The effects of time and temperature on the cumin seeds components were studied, the results have been shown that the total oil and volatile oil and its main components decreases with the passing of time and with the increasing of temperature.

In this research, the changes on these seeds during storage:
total oil, volatile oil, and the major components of volatile oils were
determined. A decrease in the total and volatile oils and all
components of volatile oils were found.
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.
This study was carried out during the growing season of 2015
to study effect od three planting date (1 Feb., 15 Feb. and 1
March) and four levels of nitrogen fertilization (0, 40, 60 and 80
kg/Ha) with interactive effect between them on some yield
components of cumin.
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).
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.
