Study of scavenging capacity of naringin extracted from Citrus uranium peel against free radicals.

In this work we determined free radical scavenging of the Citrus aurantium peel (orange peel) extract. Naringin was isolated from the fruit peel from Citrus aurantium for using liquid-liquid solvent extraction method; it was characterized by spectroscopic techniques (UV-vis and FT-IR analysis). The scavenging free radical of naringin was evaluated by monitoring radical cation bleaching of ABTS•+ by visible spectroscopy at 734 nm. Assays were compared to reference antioxidants BHT, α-tocopherol and Trolox. Results indicated a minimal extract concentration of 5.0x103 was required to present antioxidant activity; furthermore, results also showed the extract from the peel of citrus aurantium has antioxidant activity against free radicals, under our experimental conditions, naringin extract had scavenging free radicals of 43.06 % and best reference antioxidant had scavenging free radicals of 50.36 %.
