تناولت هذه الدراسة تأثير بعض العوامل البيئية على المحتوى الفينولي لنبات البقص Rhus cotinus L.. جُمعت العينات النباتية (الأوراق، الأزهار و اللحاء) من ثلاثة معارض (جنوب، غرب و شمال) على أربعة ارتفاعات (0-300،300-600،600+900،˂900م) في ريف جبلة خلال عام 2016. تم استخلاص العينات الطازجة باستخدام الايتانول 95% كسائل استخلاصي، ثم معايرة المحتوى الكلي من المركّبات الفينولية بتطبيق طريقة الفولين سيكالتو، معبراً عن النتيجة بـ (mg Gallic acid/g fw) باستخدام جهاز مقياس الطيف الضوئي (Spectrophotometer).
This study aimed at investigating the effect of some environmental factors on the phenolic contents of the Rhus cotinus L. plant. Plant samples (leaves, flowers and bark) were collected from three aspects (south, west and north) at four altitudes (0-300, 300-600, 600- 900, ˃900m) in the countryside of Jableh in 2016. The fresh samples were extracted using 95% ethanol as an extraction solution, then the total contents of the phenolic compounds were determined spectrophotometrically using the Folin-Ciocalteu reagent, expressing the result by (mg gallic acid/1g fw) using a Spectrophotometer.

This environmental research was conducted on the coastal water of Tartous city for the first time to complement previous studies along the Syrian coast. Sampling station were selected based on their different environmental characteristics from each o
thers on one hand, and their continuous exposure to the sources of pollution (oil, chemical, organic) on the other hand. It hasbeen implemented13sortiesfreelyduring the study period, which lasted fromSeptember2013untilSeptember2014. during which water samples were collected for analysis and determine the concentration of nutrients in, as vital samples to study and determine the types of phytoplankton, which collected, in addition to conducting field measurements of some properties Physical seawater (temperature, pH, salinity, oxygen dissolved concentration). This study has recorded 160 species of phytoplankton in study sites, distributed as follows: 91 species of Chryssophyta, 50 of Pyrrophyta, 11 of Chlorophyta, and 8 of Cyanophyta, their distribution has differed from one site to another and from month to monthaccordingto the differentiation in the environmental conditions.

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 chemical content of Cactus grandiflorus L was studied from
amino acids and sugars. The duration of these materials in the
branches and plant flowers was determined and the relative
proportions of these compounds were determined by using the thin
layer chromatography methods(TLC) and the highly efficient liquid
chromatography( HPLC).
The environmental factors may have an effect on the contents of the active
materials in plants. Salinity is one of these factors that can have an influence through the calcium ion
which competes with the Na+, which in turn, affects the manufacture of alkaloids present in the Datura
stramunium.
