In this study we highlight &lt;em&gt;Equisetum hyemale&lt;/em&gt;, belonging to the phylum Sphenophyta and the family Equisetaceae. Popularly, the stems of this plant are used for their diuretic, digestive, anti-anemic, and anti-inflammatory properties. Given this context, and the fact that the growth of antimicrobial resistance is a serious problem for global public health, this plant could be used as an alternative, to increase our therapeutic arsenal. Therefore, it is important to more clearly elucidate the complex structures present in plants, because these substances are mainly responsible for their beneficial and/or toxic effects. Thus, the objective of this study was evaluate the antimicrobial activity, cytotoxic and genotoxic potential of the phenolic compounds separately. The substances luteolin, ferulic acid and coumarin were identified at high concentrations by ultra-high performance chromatography-electrospray ionization-mass spectrometry (UPLC-ESI-MS). Antimicrobial activity was elucidated through microdilution in broth; the phenolic compounds were able to inhibit the visible growth of the standard bacterial strains at low concentrations. Cytotoxicity was evaluated by MTT and genotoxicity was analysed through cellular damage using a Comet assay; the results showed that it did not present cytoxicity or genotoxicity at the corresponding concentrations. With this, we suggest that &lt;em&gt;E. hyemale&lt;/em&gt; may be an alternative for the treatment of infections by microorganisms that are resistant to synthetic drugs.&lt;/p&gt;

The objective of this work was to determine the antioxidant capacity and the cytotoxicity of the AEMg. &lt;strong&gt;Methods:&lt;/strong&gt; The content of phenolic compounds in AEMg was determined by colorimetric assays. &lt;em&gt;In vitro&lt;/em&gt; tests of the antioxidant capacity of AEMg, in the sequestration of DPPH radicals, in &amp;beta;-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 &lt;em&gt;Saccharomyces cerevisiae&lt;/em&gt; and in PBMC. &lt;strong&gt;Results:&lt;/strong&gt; 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. &lt;strong&gt;Conclusion&lt;/strong&gt;: 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.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">6s</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">s135</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Regiane Sablina Almeida Bernardes&lt;sup&gt;1,2&lt;/sup&gt;, Sandra Layse Ferreira Sarrazin&lt;sup&gt;2&lt;/sup&gt;, Flaviana Alves dos Santos&lt;sup&gt;4&lt;/sup&gt;, Moacyr Jesus Barreto de Melo R&amp;ecirc;go&lt;sup&gt;4&lt;/sup&gt;, Maira Galdino da Rocha Pitta&lt;sup&gt;4&lt;/sup&gt;, Marina Ferraz Cordeiro&lt;sup&gt;5&lt;/sup&gt;, Patr&amp;iacute;cia Danielle Oliveira de Almeida&lt;sup&gt;6&lt;/sup&gt;, Ricardo Bezerra de Oliveira&lt;sup&gt;2&lt;/sup&gt;, Leoneide &amp;Eacute;rica Maduro Bouillet&lt;sup&gt;2&lt;/sup&gt;, Jos&amp;eacute; Guilherme Soares Maia&lt;sup&gt;3&lt;/sup&gt;, Rosa Helena Veras Mour&amp;atilde;o&lt;sup&gt;1,2,3*&lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
