تمت دراسة تأثير المركبات الفينولية التي تم استخلاصها من أوراق صنفين من الزيتون
السوري و هما الدان و التفاحي المنتشرين بشكل خاص في ضواحي دمشق على فعالية
إنزيم الغواياكول بيروكسيداز في خلايا سويقات الذرة الصفراء. استخدم في العمل
المركبات التي تم استخلاصها بواسطة المحلات العضوية و اللاعضوية و قد تم تمديد
المستخلصات الناتجة إلى ثلاثة تراكيز استخدمت بالعمل هي 25 % و 50 % و 100 %.
The effect of phenolic compounds were extracted from leaves of Dan
and Toufahi sorts of Syrian olives, spread particularly in Damascus
country, studied on the activity of Guaiacol peroxidise in the celles of
Kolioptyl Zea myse L. Solutions of three different concentrations of
phenolic extracts are used in the work : 25% , 50% and 100%.

Phenols were studied in the leaves of Syrian olive varieties collected from (Harasta
and Ghouta, Damascus Countryside and Qalamun). Phenolic compounds were extracted
from the olive leaf varieties after disposal of plant pigments and fatty compounds, and
total phenols separated with solvent (methanol - water).
Total Polyphenol was studied in olive leaves collected from Lattakia area
(AlQurdaha zone), where Phenolic compounds were extracted from dry Olive leaves by
using two extraction methods: maceration and Ultrasonic Device. By the both two methods

The phenolic compounds were extracted from leaves and flowers of Hops and grape
seeds from local production by soaking with different solvents (Methanol-ethanol-alcohol
