Evaluación del potencial antioxidante mediante los métodos de FRAP y Fenoles Totales en la especie Annona muricata (guanábana)

Abstract

Abstract: The antioxidant activity of the Annona muricata plant is of interest for application in various processes. In this study, the following parts of the soursop were analyzed: seeds, pulp, leaves, and rind. Antioxidant activity was assessed using antioxidant methods such as FRAP and TPC (Total Phenols). Standards such as Trolox and gallic acid were used for the analysis, respectively, for each method. These helped quantify antioxidant activity. The results showed that the leaves had the highest antioxidant activity, with a significant difference (p > 0.05), compared to the other parts, followed by the seeds. The rind and pulp did not show significant antioxidant activity. In addition, the antioxidant activities of the regions where the samples came from were compared, specifically Santo Domingo de los Tsáchilas (NC) and El Oro (LS). Finding that the antioxidant activity in Santo Domingo de los Tsáchilas is higher. Finally, the study highlights the antioxidant activity found in the leaves of the species studied.
