Since chemical properties should be the first step to understand
some biological findings for natural compounds, we first determined
the chemical profile of the hydroalcoholic extract of the
leaves of Z. joazeiro Mart. (HELZJ) and then investigated its antioxidant
activity and anti-parasitic (T. cruzi and Leishmania) and antibiotic
(bacteria and fungi) activities alone or in combination with
conventional antibiotics in current use.
