Physicochemical characterization and quantification of bioactive compounds of Antrocaryon amazonicum fruits cultivated in Brazilian Amazonia

Abstract

In this study, we reported for the first time about the physicochemical characterization, as well as the bioactive compounds in the peel and pulp of A. amazonicum fruits of two varieties harvested in Northern Brazil (Pará State) from two harvest periods (beginning and end). The peel and pulp of A. amazonicum fruits presented high contents of water (75–89%) and total carbohydrates (5–12%), whereas low total energetic value ranges (41–92 kcal/100 g, wet basis). Regardless the variety of A. amazonicum fruits, phenolic compounds were the major bioactive compounds, and the peels accumulated high contents at the beginning of the harvest period (4884–6556 mg GAE/100 g, dry basis, db), and at the end for the pulps (1394–2855 mg GAE/100 g, db). The multivariate exploratory techniques evidenced that high contents of bioactive compounds are available in the peel at the beginning of the harvest period, while at the end for the pulps.
