تم اختيار عشرة أنواع من النباتات الطبية و العطرية الواسعة الاستخدام في المجتمع السوري سواءً كبهارات أو استخدام مباشر في الطبخ أو في الطب الشعبي التقليدي، و هي أكليل الجبل، الورد الجوري، البابونج، السماق، زهر الزيزفون، حبة البركة، الزعتر الأخضر، النعنع الأخضر، و ورق الغار و المليسة. تم تقدير نسبة الرطوبة -ناتج الاستخلاص- المحتوى من المركبات الفينولية -النشاط المضاد للأكسدة في محلات من الميثانول و الإيثانول و الأسيتون و الماء في النباتات المدروسة. قدر المحتوى من المركبات الفينولية باستخدام طريقة الفولين Folin-Ciocalteu, أما النشاط المضاد للأكسدة تم تقديره بطريقة DPPH.
Ten medicinal plants were chosen from various plants in Syria which used as spices or cooked and Syria traditional medicine. Their names Rosemary, Damask rose, Chamomile, Sumac, Silver linden, Black cumin, Thyme, Mint, Laurel and lemon balm. Moisture, yield of extraction, total phenolic content (TPC) and antioxidant activities of methanol, ethanol, acetone and aqueous extracts of medicinal plants were investigated. The TPC were measured by Folin-Ciocalteu method, and the antioxidant activity was assessed by the scavenging activity towards 2, 2′-diphenyl- 1-picryl hydrazyl (DPPH)-radical.

In this research, the
antioxidant capacity(DPPH method), and total phenolic content (assayed
by Folin-Ciocalteu method), ,flavonoids, anthocyanins (pH differential
method) and ascorbic acids(2,6-dichlorophenol indophenol) in three fruit
tissues (
peel, pulp and whole fruit), of four apple cultivars commonly in
Syria(Red Delicious, Rome Beauty, Starking Delicious, Golden
Delicious), were studied.
Classified locality Yeasts have been culturing in plantology
department at the Faculty of Science-University of Damascus,
from genera of Pichia, Candida, Geotrichum, Rhodotorula, Phaffia
on solid Czhapek agar medium, and after incubated in appropr
iate
conditions their colonies showed evidence of different colors to
produce a variety of pigments. Then it cultured in liquid Czhapek
medium to increase biomass and the genera producing
endocellular pigment separated from the medium by filtration with
added ethanol on them and blasting cells by ultrasonic waves to
get a pigment, while the genera producing exocellular pigment is
separated about the liquid medium also by filtration but the solvent
was added to the medium containing the pigment.
The medicinal and aromatic plants (thyme Khalili) is one of important economic
crops were introduced to the Syrian Agriculture recently "as one of the most important
alternative crops, especially" in the coastal region, The goal of research is to c
larify the
economic importance of agriculture thyme Khalili in the coastal region, This study was
conducted on all farmers who were counted on the ground in Tartous and Latakia
Governorates, there were 213 farmers ,with planted area reached to 565 acres in 2015.The
indicatives of economical feasibility based on data and statements gathered from site of
research and relying,were used in the economical evaluation .The study showed that the
totally achieved profit per annum from one acre of (thyme khalili) amounted to
151451.81 Syrian Pounds , and profitability coefficient in proportion to the productivity
cost has amounted to 283.64%, also the time indicator of capital recovery for (Thyme
Khalili) has amounted to 2.82 years.
The aim of this study was to determine the
phenolic content in the fruit, leaf and root samples of the fennel
plant and in the fruit samples from several different areas, and
then to determine the antioxidant capacity of these samples.
The antioxidant activity of pomegranate juices extracted by two methods
was determined using three methods: β- carotene, Linoleic acid emulsion, and
DiPhenel Picryl Hydrazyl (DPPH). The juice was extracted by separation arils
from fruits and squee
zed using Cyclone machine (T-1), while the second
extraction method included squeezing the whole halve fruit with previous
machine, (T-2). The potential compounds were determined using ethanol in a
comparison with Butylated hydroxyl Anisole (BHA) as reference antioxidant.
There were significant differences (P<0.05) in the antioxidant activity between
the treatments in all measuring methods. The means of antioxidant activity
amounted to 82.66% in T-1, 86.82% in T-2 and 86.98% in BHA. There was
significant relationship between total phenols and antioxidant activity in all
treatments.
