DIAZ-URIBE, Carlos E.; VALLEJO, William; OLIVEROS, Grace  e  MUNOZ, Amner. Study of scavenging capacity of naringin extracted from Citrus uranium peel against free radicals. Prospect. [online]. 2016, vol.14, n.2, pp.31-35. ISSN 1692-8261.  https://doi.org/10.15665/rp.v14i2.677.

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, a-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 %.
