چکیده :

In this study the Antioxidants with natural origin attracted a considerable attention. In the present work methanolic extract fractions of each parts (leaf, leafstalk, stem, green fruit, ripe fruit and seed) of the plant were subjected to a screening for their possible antioxidant capacity by using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and β-carotene-linoleic acid assays. Also, total phenolic constituents of extracts were examined by Folin ciocalteu reagent. Of all samples, leaf extract of Rhus coriaria L. showed the high ability to reduce DPPH and β-carotene oxidation inhibition but seed extract of the plant showed the high amount of phenolic compound equivalent with Gallic acid. (IC50 = 7.82 ± 0.17 against IC50=19.05±0.80 for BHT as blank in DPPH test, Inhibition percent=82.02% against Inhibition percent=89.47% for BHT as blank for β-carotene-linoleic acid assay and 331.53±32.28μg/ml in total phenolic constituents of extracts).
