Natural products represent a rich and promising source of novel, biologically active chemical entities for treating Leishmaniasis. This study investigates the anti-leishmanial activity of n-butanol, aqueous, and chloroform fractions obtained from crude methanolic extract of Albizia gummifera seed in in-vitro (peritoneal mice macrophage) model after one time treatment. The anti-lesihmanial activity was determined from the minimum inhibitory concentration (MIC), infection rate (IR) and multiplication index (MI) against L. donovani. Cyto-toxicity of the fractions was also assessed against Vero cells. In addition to this secondary metabolites were determined by phytochemical screening. The MIC value of n-butanol, aqueous, chloroform and amphotericin B were 11.2 μg/ml, 33.5 μg/ml, >89 μg/ml and 1.32 μg/ml, respectively. N-butanol and aqueous fractions significantly inhibit the growth of intra-cellular L. donovani amastigote (P>0.05) compared to amphotericin B whereas the chloroform fraction did not revealed any significant leishmanicidal effect (P<0.05) with their respective parasitic infection rate, multiplication index and MIC levels. Based on these data, the n-butanol and aqueous fractionates of A. gummifera seeds exhibit considerable in-vitro anti L. donovani activity and may be promising anti-leishmanial herbal remedy candidate that support the traditional use of the plant.
