Abstract
Using antioxidant agents is purpose of the present study. The antioxidant effects of n-hexan, ethyl acetate and methanol extracts of roots and stalks of Rhubarb(Rheum ribes) and roots , bark of roots ,leaves and fruits of Syrian mesquite (Prosopisfarcta) on free radicals have been evaluated in this study. Different concentrations of extracts were subjected to evaluate total flavonoid content, total phenolic content, and DPPH free radical scavenging activity. Total flavonoid content of the methanol extract for roots of Prosopisfarcta showed significantly higher content (331.62 µg rutin E/mg of extract) than other extracts. Ethyl acetate extract for leaves of Prosopisfarcta exhibited a significant dose dependent inhibition of DPPH activity with 50% of inhibition (IC50) at concentration of 22.47 µg/ml. Also, it showed the highest value of phenolic content (143.7 µg GAE/mg of the extract). Possessing properties of antioxidant may qualifies these extracts to be used as a medicines.
