• Resumen

  • 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%.
