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&#8729;+ 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 %.]]></p></abstract>

El extracto de naringina fue separada de la cáscara de la fruta de la Citrus aurantium utilizando la extracción líquido-líquido como método de separación; el compuesto obtenido fue caracterizado por medio de espectrofotometría UV-Vis y espectroscopia infrarroja con transformada de Fourier (FT-IR). La actividad antioxidante de la naringina fue determinada monitoreando el cambio en la concentración del catión radical ABTS&#8729;+ por espectrofotometría a una longitud de onda de 734 nm; como patrones de referencia se utilizó el BHT, a-tocoferol y el Trolox. Los resultados mostraron que el extracto de la cáscara de la Citrus aurantium presenta actividad antioxidante contra radicales; bajo nuestras condiciones experimentales, el extracto presentó un actividad antioxidante del 43.1 %, en comparación el mejor resultado para los antioxidantes de referencia fue del 50.4 %.]]></p></abstract>
