Potencial antioxidante e quantificação dos compostos fenólicos presentes em folhas de Mauritiella armata (Mart.) Burret

Abstract

Mauritiella armata popularly known as xiriri, a palm tree present in the Brazilian Cerrado that stands out for its beauty and its uses in human nutrition, presenting high nutritional and cultural value. The species is rich in lipids and bioactive compounds, such as carotenoids and phenolic compounds, which have great antioxidant capacity and can play an important role in disease prevention. The objective of this study was to identify the production of total phenolic compounds and antioxidant activities in M. armata leaves collected in two different areas of Vereda Almescla, characterized as the edge (dry area) and bottom (wet area) locations in Bonito de Minas, MG . The identification of different compounds present in M. armata leaves were analyzed by UHPLC-ESI MS/MS chromatography. The antioxidant activity was evaluated by the DPPH free radical scavenging method and the quantification of the content of total phenolic compounds was carried out by spectrophotometry using the Follin-Ciocalteau method. Thus, in the results we observed that chromatography identified important compounds such as arginine, citrulline and tyrosine, which are essential amino acids, ac. chlorogen is an important antioxidant. Phenolic compounds during the month of December had a decrease in production in the two areas studied during the period considered. As for the antioxidant potential, it was observed that in practically all months of collection, there was a high capacity to neutralize the DPPH radical in collected leaves.
