Abstract
The antimalarial activity of four Cryptolepis sanguinolenta based herbal
preparations namely NBOl, NB02, Cryptoquine and Nibima, were studied using
Plasmodium berghei (ANKA) in ICR mice. The herbal preparations were evaluated
for chemosupressive activity during an early infection with P. berghei in mice and
also for possible repository activity to ascertain whether they could be useful as
prophylaxis. Each mouse used in the study was infected with a standard inoculum of 1 x 106 parasitised RBCs intraperitoneally. P. berghei infected mice which were treated with Cryptolepis sanguinolenta based herbal preparations showed chemosuppression in all four herbal preparations for the 4-day suppressive test. Also, the results of the repository activity of the herbal preparations showed that all four herbal preparations have promising repository activity judging by theis ability to reduce parasitemia in mice. Generally, the results of the mean survival time of mice treated with all four herbal preparations under the 4-day tests compares werrwith those treated with chloroquine. The results of the study have shown that all four Cryptolepis sanguinolenta based herbal preparations appear to have both schizontocidal and repository activity against Plasmodium berghei in mice. This implies that all four herbal preparations may be useful in the prevention and treatment of malaria.
