Abstract: Antioxidants were extracted from the pomegranate and orange peels by ethanol and their activity were evaluated by DPPH (2, 2-diphenyl-1-picrylhydrazyl) radical scavenging, Ferric-reducing antioxidant power assay. The total phenolic compound (TPC) was determined by the Folin-Ciocalteu method to quantify the amounts of Phenolic contents. The (Pomegranate Peel Extracts) PPE exhibited higher total phenolic content (TPC) 139.40 mg/g GAE while the orange peel extracts (OPE) showed three times lower TPC of 35.73 mg/g GAE. The result of antioxidants activity of PPE showed the radical scavenging activity of 92.38% at the concentration of 35µg/mL where as the OPE showed the radical scavenging activity 85.68 % at a higher concentration of 700 µg/mL. The results of FRAP of the PPE showed the Abs range of 0.08-1.40Abs at700nm while the results of the OPE exhibited 0.08-0.24 Abs at700nm. The PPE showed about six times higher reducing power compared to OPE, at the concentration of 700 μg/mL and exhibited the 1.40 Abs at 700 nm while at the same concentration OPE showed only 0.24 Abs at 700 nm.The PPE showed a higher reducing power of 1.43 optical densities. The above results indicate that the PPE is good source of the phenolic compounds and higher antioxidant activity as compared to OPE.
