Preliminary phytochemical and antileishmanial studies of the ethanolic extracts of Pterodon pudescens
Pentavalent antimonials are the first choice for the treatment of human leishmaniasis. However in rural areas the traditional plants may be preferred for the treatment of lesions. In recent years a number of papers are published related to the natural products especially plant derivative with infectious diseases. The present work was undertaken to evaluate the antileishmanial activity of Pterodon pubescens which is a native tree widely distributed over the central region of Brazil and used in folk medicine as wine infusions to treat inflammatory disease. The phytochemical screening and the biological essay of ethanolic extract of Pterodon pudescens (PPE) leaves at the concentrations of 150, 300, 450, 600 µg/ml were tested in vitro in Leishmania amazonensis-infected macrophages to support its traditional medicinal use as a leishmaniasis remedy. Phytochemical screening of PPE has shown the presence of catechemical tannins, steroids, triterpenoids and flavonoids. The biological test suggests that PPE were found to control parasite burden of cell cultures in dose-dependent manner. These findings highlight the fact that the apparent potency of Pterodon pudescens compounds, together with their widely distribution over Latin America and Brazil, may represent a promising antileishmanial agent.
