Seeds of three species of Costa Rican pioneer plants were tested for anti-parasitic activity against Leishmania tarentolae. Initial screening of crude seed extracts revealed leishmanicidal activity in Bocconia frutescens with an IC50 value of 2.61 µg/mL. Further fractionation and compound identification revealed four benzophenanthridine compounds in the Bocconia seed extract, all of which showed leishmanicidal activity with IC50 values in the ranges of 10-20 µg/mL. Preliminary data show low mammalian toxicity of these compounds, suggesting potential for medicinal use.
