“…Different secondary metabolites are responsible for the biological effects of medicinal plants (De Araújo et al, 2018). Consistent with this, the literature has related the antimicrobial activity of extracts with the presence of phenolic compounds (Harsha & Anilakumar, 2014;Cartaxo-Furtado et al, 2015), flavonoids (Cartaxo-Furtado et al, 2015) and tannins (Gowri & Vasantha, 2010;Cartaxo-Furtado et al, 2015).
