ترجمة الملخص

The effect of aqueous and methanolic (aerial and root) extracts of Euphorbia guyoniana,which was harvested from Al-Bayada area in Oued Souf, was studied. The study aims the ability of these extracts to inhibit free radicals and bacteria growth, inaddition to inhibiting one of the important enzymes that have a key role in raising the sugar in the blood (α-amylase).The process of extracting the active compounds of E.guyoniana was done by using two solvents, water and methanol for its separate parts (aerobic/radical), obtained showed that the aerial and root parts of the plant contain these metabolites,except for the that were absent from the root.Stem and leaf anatomy of the plant shows that the stem is characterized by the latex-secreting glands and the absence of stomata on the axial surface of the leaf.Measuring the antioxidant activity of the various extracts was done using the DPPH method. The results showed that all extracts had an inhibitory response tofree radicals. DPPH varied in intensity according to the type of solvent and the plant part.It was noted that the two methanolic extracts had the highest antioxidant activity. The bestis 0.019±0.164(mg/ml).In a second step, the antibacterial activity was measured, as the results showed that theaqueous extracts had no effect on the bacterial species used in the study, while there wasan effect on all these species in the methanolic extracts, especially the aerobic part. =
