Abstract

Purpose: To investigate the in vivo antiplasmodial effect of Mangifera indica aqueous extract in Plasmodium berghei-infected mice, and to characterize  its phytochemical constituents and their mechanism of action.


Methods: The plant leaves (250.71 g) and stem bark (509.34 g) were weighed, macerated in 5 L of boiled, distilled water for 72 h, and filtered. In vivo  antiplasmodial evaluation of the extract was carried out using Plasmodium berghei-infected mice. The leaf and stem bark extracts were subjected to gas chromatography-mass spectroscopy (GC-MS) analysis for characterization of their chemical constituents.


Results: The leaf/stem bark (1:2) extract (88.27 %) exhibited chemosuppressive activities that was better than artesunate (88.04 %) and artemisinin-based  combination therapy (ACT, 84.60 %). Its schizonticidal activities (98.63 %) revealed a better therapeutic response when compared with artesunate (92.34  %). Spectroscopic analysis showed linoleic acid esters and other compounds.


Conclusion: Therapeutic response of leaf/stem bark (1:2) extract exhibit  superior schizonticidal activity to ACT and artesunate. Furthermore, the linoleic acid esters in Mangifera indica aqueous extract may contribute to strong  antimalarial activity by inhibiting fatty acid biosynthesis.
