Caracterização fitoquímica e avaliação da atividade antioxidante de Dipteryx alata Vogel (Fabaceae)

Studies show some biological properties associated with Dipteryx alata Vogel (Fabaceae), a typical species from Cerrado. Therefore, this work aimed to characterize the phytochemical compounds and analyze the antioxidant activity of the ethanolic extracts from the leaves and pulp of Baru. The leaves and fruits were collected randomly from ten individuals, in the city of Arinos (MG). The chemical compounds of the ethanolic extracts were analyzed by chemical reactions described in specific protocols. The content of phenolic compounds was quantified by spectrophotometry. Furthermore, the DPPH reduction method was used to verify the antioxidant activity. The results revealed a high antioxidant activity and a high content of phenolic compounds in Baru leaves, meanwhile in the pulp the values were lower. The obtained results with leaves and pulp extracts from Baru indicate a great antioxidant potential and additional studies should be performed to isolate the compounds, which are responsible for this activity in the plant.
