Capacidad antioxidante de poblaciones silvestres de “tara” (Caesalpinia spinosa) de las localidades de Picoy y Santa Fe (Provincia de Tarma, departamento de Junín)

Abstract

Peru is the main supplier of , because our country has a variety of climates and soil types, by allowing the crop during most of the year. Junin department has natural populations of tara who have not yet been characterized biochemical or genetically, which could be harnessed for the benefit of local communities. In this work we report the antioxidant capacity of tara from the localities of Picoy and Santa Fe, both located in Tarma, Junin. We used the technique of DPPH and ABTS to evaluate the antioxidant capacity for the determination of phenols and flavonoids were used Folin-Ciocalteau reagent according to the technique of Singleton. Picoy sample reported a higher amount of phenols being of 563.70 mg/g dry extract, while the amount of flavonoids was 0.664 mg/g. The antioxidant capacity showed a better response in the sample of Picoy, reporting through a DPPH IC50 1.244 mg/ml and 35.3% ABTS inhibition. These data could be used to increase the added value and improve the supply of this resource in this area due to better antioxidantl characteristics.
