ABSTRACT
The antiplasmodial activity of the aqueous leaf extract of Mucuna pruriens (M. pruriens) was evaluated against Plasmodium berghei NK-65 strain in mice. The plant was selected based on their traditional claims for treatment of fever and other malaria related diseases in southeastern region of Nigeria. An aqueous leaf extract (90 - 270 mg/kg) was investigated for antiplasmodial activity against Chloroquine-sensitive Plasmodium berghei infections in mice. The antiplasmodial activity during early and established infections as well as prophylactic action of the plant in blood was investigated. Chloroquine (10 mg/kg) and pyrimethamine (1.2 mg/kg) were used as positive controls. The extract (90 - 270 mg/kg) dose dependently reduced parasitaemia induced by Chloroquine sensitive Plasmodium berghei infection in suppressive, prophylactic and curative models in mice. The extract at these doses caused 60.06 - 71.75% inhibition of parasitaemia in the suppressive test, 65.97 - 84.38% parasitaemia inhibition in prophylactic test and a mean survival time of 16 - 30 days representing 64.41- 89.71% inhibition of parasitaemia in the curative test. These reductions were statistically significant (P<0.05) comparable to that of the standard drug used (Chloroquine and Pyrimethamine). These results show that the aqueous leaf extract of M. pruriens possesses significant (P<0.05) antiplasmodial activity which confirms its use in folkloric medicine in the treatment of fever and other malaria-related disease.
