Abstract

The purpose of this work was to evaluate the antioxidant capacity of Prosopis pallida (Fabaceae) fruits “algarrobo”, in addition to determine their main chemical components. Fruit purified extracts from the regions of Tumbes, Piura, Lambayeque, and La Libertad (Peru) were evaluated using infusion, decoction, and alcoholic extraction at concentrations of 45, 70 and 96%. To measure the antioxidant capacity of the extracts, the determination of total phenolics content was performed, followed by the antioxidant evaluation using DPPH, FRAP and ABTS. The chemical identification was carried out through UHPLC-UV-MS/MS. The results showed that the decoction of the sample from the region of La Libertad, as well as the ethanol extracts at 45% of the samples from Tumbes and Lambayeque presented greater antioxidant capacity. Moreover, ten major substances of these extracts were identified: nine phenolic derivatives (vicenin II as the main constituent of the extracts) and one diterpene (7-oxodehydroabietic acid).
