TRYPANOCIDAL EFFECTS OF SOME TROPICAL PLANT EXTRACTS - A REVIEW.
The extracts of Morinda Lucida, Combretum dolicopetalum showed significant (P < 0.05) trypanocidal activity at high dosage levels. The extract was most effective when given simultaneously with infection. Both the PCV and clinical symptoms improved after treatment with the extracts. Alstonia boonei extracts appeared to reduce the level of parasitaemia although this was not significant when subjected to ANOVA. The movement of the organisms became sluggish and were clumped together in the extracted groups. The trypanocidal effects of extracts will require further experimentation after fractionation and characterisation using chromatographic and spectroscopic techniques.
