This study was undertaken to evaluate the antileishmanial activity of the fruit rind of <jats:italic>Myristica malabarica<\/jats:italic> that is used as a spice and is also credited with medicinal properties. The antipromastigote activity of different extracts\/fractions of <jats:italic>M. malabarica<\/jats:italic> and its constituent diarylnonanoids were evaluated in <jats:italic>Leishmania donovani<\/jats:italic> promastigotes (MHOM\/IN\/83\/AG83) using the MTS\u2010PMS assay. Preliminary screening of the ether extract (R1) with its crude methanol fraction (R2) and two fractions (R3 and R4) revealed that R2 had potent leishmanicidal activity (IC<jats:sub>50<\/jats:sub> 31.0 \u00b5g\/mL), whereas R3 and R4 showed poor activity. Fractionation of R2 yielded four diarylnonanoids (malabaricones A\u2013D, designated as Mal A, Mal B, Mal C and Mal D, respectively). The IC<jats:sub>50<\/jats:sub> values of Mal A\u2013D were 16, 22, 27 and &gt;50 \u00b5g\/mL, respectively. Taken together, the data suggest that the methanol extract of <jats:italic>M. malabarica<\/jats:italic>, especially its constituent compounds, Mal A and Mal B, have promising antileishmanial activity meriting further investigations regarding the underlying molecular mechanism(s) of action with a view towards future drug development.
