Prospection of antioxidant action of phytochemicals of Mimosa tenuiflora (Jurema-Preta)

Abstract

Objective: The objective this work was to observe phytochemical studies and the antioxidant action of extracts and fractions of different parts of Mimosa tenuiflora (Willd) Poir. Methodology: Search in the database: PubMed, SciELO, Medline via BVS, Lilacs via BVS, Science direct and Cochrane, through the scientific descriptors: “Mimosa tenuiflora and antioxidant”; “Mimosa tenuiflora and phytochemicals”; “Mimosa tenuiflora”, has published from january 1990 to june 2021. The inclusion criteria used were: 1) phytochemical studies of Mimosa tenuiflora; 2) antioxidant studies of Mimosa tenuiflora in vivo and in vitro models; 3) available in full texts. The exclusion criteria were articles that were not related and relevant to the theme, duplicated articles and those unavailable for full reading. Results: 24 studies identified the phytochemicals of M. tenuiflora, only 5 of these studies showed antioxidant activity in vitro. The compounds present in the extracts and fractions of different parts of the plant were phenolic compounds, flavonoids, flavonols, xanthones, flavones, polyphenols and tannins. Conclusion: The studies showed wide phytochemical variety present in extracts and fractions of different parts of the plant and few studies showing antioxidant activity of phytoconstituents of M. tenuiflora. The phenolic, flavonoids and polyphenols compounds were the major compounds in the studies involving analysis of the antioxidant activity of M. tenuiflora.
