Abstract
El arándano nativo crece en forma silvestre en los andes sudamericanos, la fruta es consumida por las personas debido a que posee características sensoriales agradables. El objetivo fue determinar el contenido de polifenoles totales, antocianinas y capacidad antioxidante en frutos de arándano nativo procedentes de los distritos de Tambogan y Llacon de la Región Huánuco Perú. Las muestras de arándano nativo fueron colectadas y se evaluaron el contenido de polifenoles totales, antocianinas y actividad antioxidante mediante la técnica de DPPH y ABTS. Los frutos de arándano nativo de las dos zonas en estudio reportaron mayor contenido de polifenoles totales y antocianinas y secuestro del catión ABTS, mientras que la actividad antirradical frente al DPPH del arándano comercial fue superior a los arándanos nativos. En conclusión, por sus características intrínsecas los arándanos nativos se perfilan como un recurso alimentario con excelentes beneficios antioxidantes.
Native blueberry grows wild in the South Americans Andeans, the fruit is consumed mainly for its pleasant sensory characteristics. The aims of the research were to determine the content of total polyphenols, anthocyanins, and antioxidant capacity in native blueberry fruits from the Tambogan and Llacon districts of the Huánuco Region of Peru. Samples of native blueberries were collected, and the content of total polyphenols, anthocyanins, and antioxidant activity were evaluated using the DPPH and ABTS techniques. The native blueberry fruits from the two study areas reported higher content of total polyphenols and anthocyanins and ABTS cation sequestration. In contrast, the antiradical activity against DPPH of the commercial blueberry was higher than that of the native blueberries. In conclusion, due to their intrinsic characteristics, native blueberries are emerging as a food resource with excellent antioxidant benefits.
