Antimalarial Activities of Hydromethanolic Crude Extract and Chloroform Fraction of Leaves in Infected Mice.

BACKGROUND

is utilized in traditional medicine of Ethiopia for malaria treatment and possessing in vitro antimalarial activity. However, no in vivo study was conducted to substantiate the claim. The aim of this study was to judge the antimalarial activity of extract in vivo in -infected mice.

METHODS

was inoculated to healthy mice, and hydromethanolic crude extract and chloroform fraction of leaves at 100 mg/kg/day, 200 mg/kg/day, and 400 mg/kg/day were administered. Percent parasitemia inhibition, percent change in bodyweight, hemoglobin level, and mean survival time were determined. Data were analyzed using one-way ANOVA followed by post hoc Tukey HSD test with IBM SPSS software version 20.0 statistical package and < 0.05 considered as statistically significant.

RESULTS

The chemosuppressive test of hydromethanolic crude extract at 100 mg/kg/day, 200 mg/kg/day, and 400 mg/kg/day ranged from 27.09% to 67.72%, and chloroform fraction had 35.21%-78.19% parasitemia suppression, respectively. For curative test on day 5, hydromethanolic crude extract at 100 mg/kg/day, 200 mg/kg/day, and 400 mg/kg/day ranged from 25.58% to 48.76%, chloroform fraction at 100 mg/kg/day, 200 mg/kg/day, and 400 mg/kg/day and chloroquine base at 10 mg/kg showed 46.36%-74.42% and 92.87% percent parasitemia inhibition, respectively, and also the results to both tests were highly significant ( < 0.001) compared to the negative control. Maximum effects on chemosuppressive, curative, prevention of weight loss, and reduction in hemoglobin were observed at higher doses of the hydromethanolic crude extract and chloroform fraction.

CONCLUSION

From this study, hydromethanolic crude extract and chloroform fraction of leaves have shown promising antimalarial activity. The findings support the traditional claim of leaves for malaria treatment; however, species variation could also limit such a straightforward extrapolation of the findings of this study in humans.
