Oxidation reactions venture human health due to the production of free radicals. Additionally, by creating some compounds, reduce sensory and nutritional quality of food. Recently, performed many attempts to find natural and safe antioxidants from different plant sources. In this study, total phenolic and antioxidant activity of sour orange (Citrus aurantium) hydroethanolic and methanolic peel extract in compare with BHT examined. Total phenolic content of hydro-ethanolic and methanolic peel extract was 59.38±0.82 and 50.96±0.51 mg Gallic acid/g extract, respectively. In testing percent of inhibition of free radicals (DPPH and ABTS), the extracts showed a significant inhibitory effect but there is a significant difference, between hydro-ethanolic and methanolic extract in ABTS test. Both extract also showed reducing effect. Our findings showed that orange peel extract had relatively good antioxidant activity in compare to standard antioxidant (BHT), so it has proposed as a potential source of natural antioxidants in food and pharmaceutical industries.
