Abstract:
The anti-malarial potential of different parts of Allophylus africanus P. Beauv and Tragia benthamii Baker were determined in vivo for suppressive, curative and cytotoxic activities in mice receiving 0.2 mL of a standard inoculum size of 1 × 10(7) infected erythrocytes of Plasmodium berghei (NK-65) intraperitoneally. The A. africanus extracts suppressed parasitaemia following administration to infected mice by 92.82%-97.81% on day 7 post-infection against 96.81% for chloroquine. The infected extract-treated animals had significantly moderate (P < 0.05) packed cell volume (PCV) compared with the infected, untreated animals. Phytochemical screening revealed a predominance of tannins, saponins, flavonoids and carbohydrates in all parts of A. africanus, and alkaloids instead of flavonoids in the extract of T. benthamii. The results suggest that the extract possesses considerable antimalarial activity. These results support further studies on A. africanus.
