ABSTRACT

The antileishmanial activity of extracts and phytoconstituents of Moringa oleifera Lam. was investigated in vitro against promastigotes of Leishmania donavani. The 70% ethanolic extract of roots and the methanolic extract of leaves showed moderate inhibitory activity with IC50 values of 83.0 microg/ml and 47.5 microg/ml, respectively. Antileishmanial activity of the methanolic extract of leaves increased upon fractionation, as its ethyl acetate fraction was found to be more active with an IC50 value of 27.5 microg/ml. The most active antileishmanial compound niazinin, a thiocarbamate glycoside isolated from this fraction, showed an IC50 value of 5.25 microM. Results presented in this study indicate that extracts from M. oleifera may be developed as an adjuvant therapy for the treatment of leishmaniasis.
