Aim: This report was aimed to investigate both the chemical composition and the antioxidant activity of two extracts from Mentha rotundifolia aerial parts. Methods: Aqueous and acetonic extracts were obtained by decoction and Soxhlet apparatus, respectively. Total polyphenols contents were determined using Folin- Ciocalteu reagent whereas flavonoids were evaluated by AlCl3 method. LC-MS/MS method was carried out to reveal the phytochemical composition of extracts. Some tests were used to evaluate the in vitro antioxidant activity of extracts such as DPPH free radical scavenging assay, ABTS+ radical cation decolorization assay, OH{\textbullet} radical scavenging assay, ferrous ion chelating, reducing power and β-caroten/linoleic acid bleaching assay. Results: The results showed that the aqueous extract was richer on polyphenols and flavonoids comparing to the acetonic extract. The analysis by LC-MS/MS allowed to identify many phenolic compounds in extracts, predominated by rosmarinic acid. In addition, the extracts were found to possess a significant antioxidant activity. Conclusion: Accordingly, it can be concluded that M. rotundifolia is quite rich in phenolic compounds and has a good antioxidant activity.

Introduction: Ethnobotanical studies report that Myrcia guianensis (Myrtaceae), belonging to a group of plants known as pedr\á-ume-ca\á or insulin plant, is used as a tea to treat various diseases, including diabetes, a metabolic disorder that leads to the constant production of free radicals. The objective of this work was to determine the antioxidant capacity and the cytotoxicity of the AEMg. Methods: The content of phenolic compounds in AEMg was determined by colorimetric assays. In vitro tests of the antioxidant capacity of AEMg, in the sequestration of DPPH radicals, in \β-carotene bleaching, in the FRAP, as well as in human fibroblast cells of the MRC-5 lineage, were performed. The cytotoxic activity of AEMg was evaluated in assays with eukaryotic cells from yeast Saccharomyces cerevisiae and in PBMC. Results: The results showed that the AEMg is rich in phenolic compounds, presenting high antioxidant potential in all the tests carried out, including in human fibroblast cells of the MRC-5 lineage, besides not being toxic to eukaryotic cells. Conclusion: The AEMg, rich in antioxidant compounds and no toxicity, can be used as source of natural antioxidant in the treatment of metabolic diseases to combat free radicals.
