Developing countries, where malaria is one of the most prevalent diseases, still rely on traditional medicine as a source for the treatment of this disease. In the present study, six selected plants (Acalypha fruticosa,Azadirachta indica,Cissus rotundifolia,Echium rauwalfii,Dendrosicyos socotranaandBoswellia elongata) commonly used in Yemen by traditional healers for the treatment of malaria as well as other diseases, were collected from different localities of Yemen, dried and extracted with methanol and water successfully. The antiplasmodial activity of the extracts was evaluated against fresh clinical isolates ofPlasmodium falciparum. The selectivity parameters to evaluate the efficacy of these medicinal plants were measured byin vitromicro test (Mark III) according to World Health Organization (WHO) 1996 & WHO 2001 protocols of antimalarial drug tests. Among the investigated 12 extracts, three were found to have significant antiplasmodial activity with IC50values less than 4 µg/ml, namely the water extracts ofA. fruticosa,A. indicaandD. socotrana. Six extracts showed moderate activity with IC50values ranging from 10 to 30 µg/ml and three appeared to be inactive with IC50values more than 30 µg/ml. In addition, preliminary phytochemical screening of the methanolic and aqueous extracts indicated the presence of saponins, tannins, flavonoids, terpenoids, polysaccharides and peptides.

The search for antimalarial compounds has been necessitated by the resistance of Plasmodium falciparum to almost all antimalarial drugs. The aim of this research was to determine in-vitro antimalarial activity of extracts of some indigenous plants species in Kebbi State. Plant extraction was carried-out by maceration using ethanol and water as solvent. The antiplasmodial activity of the extracts was evaluated against fresh clinical isolates of P. falciparum using WHO method of in-vitro micro test. Phytochemical screening was also carried out on the extract to deduce the active chemicals present in the plant extract. All plant extracts demonstrate dose dependent antimicrobial activities with IC50 Less than 50%. However highest growth inhibition of the P. falciparum was demonstrated by aqueous and ethanol extract of A. indica with IC50 7.4µg/ml and 8.6µg/ml respectively followed by ethanol and aqueous extract of C. occidentalis with IC50 15.3µg/ml and 18.0µg/ml respectively. Least antimalarial activity was demonstrated by aqueous extract of M. oleifera with IC50 33.5µg/ml while ethanolic extract of M. oleifera demonstrated IC50 of 20.50µg/ml. M. indica ethanolic and aqueous extract also demonstrated moderate antimalarial activity with IC50 18.8µg/ml and 24.5µg/ml. The phytochemical screening of medicinal plants showed the presence of tannins, saponins, alkaloids, flavonoid, phenol and cardiac glycosides in the extracts, which may be responsible for the antiplasmodial activity. This result justifies the traditional use of the plant in malaria treatment and further research is suggested to identify and characterize the active principles from the plants.

Abstract Background: In traditional medicine, the floral diversity permits the inhabitants of North Cameroon to use a great number of plants to fight against Malaria. The aim of this study was to identify plants used in traditional medicine to treat malaria, and to verify the scientific basis for the use of one of these plants in the locality of Gamba.Methods: An Ethnopharmacological survey was carried out on 15 traditional healers. We collected data on use of medicinal plants using questionnaires. Then in-vivo antimalarial activity of the decoctioned and macerated aqueous extracts of khaya senegalensis trunk bark was evaluated. The 4-day suppressive peters test was realised on mus musculus swiss albino mice. On day one, mice were infected with 107 plasmodium berghei parasitized red blood cells through intra-peritoneal inoculation. 2 hours after infestation, mice in batches of 6 were treated orally at a dose of 75, 150.300 mg/Kg for macerated aqueous extract and 65, 120.260 mg/Kg for decoctioned extract daily during 3 days at an administration volume of 10 ml/Kg. An extract was considered (% reduction): Highly active (between 100-90 %); moderate (between 90-50 %); weak (between 50-10 %); Inactive (between 0 %). P-values <0.05 were considered statistically significant.Results: A total of 18 plant species belonging to 12 families were identified for the preparation of 12 recipes. The decocted aqueous extract of khaya senegalensis showed moderate anti-plasmodial activity (% reduction = 52.46%) at the highest dose of 260 mg/kg with p<0.001 compared to the positive control group. The aqueous macerate at doses of 150 and 300mg/kg gave respectively a percentage reduction of parasitaemia of 59.42% and 71.80% and also showed moderate anti-plasmodial activity; with p<0.001 between the different extracts and the positive control (99.18%).Conclusion: In conclusion, extracts of khaya senegalensis showed moderate anti-plasmodial activity. It would therefore be necessary to evaluate the anti-malarial activity in-vivo and the toxicity of the aqueous extracts macerated using other solvents and also test the other plants listed.

The objective of the present study was to investigate phytochemical components, antiplasmodial activity (in vivo) and evaluate the toxicity of two local medicinal plants, namely, Salvadora persica L. and Balanites rotundifolia (Van Tiegh.) used in Afar ethnomedicine for the treatment of malaria. In this study, phytochemical screening has been done using standard methods and the existence of antiplasmodial compounds was detected in these plant extracts. Four-day Peter’s test was used to determine parasite inhibition, PCV was determined by Wintrob’s method, and effects against loss of body weight and improvements on survival time were determined. LD50s of the crude extracts have been also done. Acute toxicity studies of the extracts were carried out in Swiss albino mice prior to antimalarial activity test. All extracts revealed no obvious acute toxicities on mice up to the highest (5000mg/kg) dose given. The crude extract was estimated to have oral median lethal dose higher than 5,000 mg/kg. With the 4-day suppressive test, both plant extracts demonstrated dose-dependent significant reduction in parasitemia level at all test doses compared to the negative control: in the extract of B. rotundifolia 500 mg/kg extract (60.59±3.25%), 350 mg/kg extract (48.1±1.4), and 200 mg/kg extract (41.33±1.1%) were found. And in case of S. Persica 500 mg/kg extract (50.6±4.01%), 350 mg/kg extract (35.85±0.89), and 200 mg/kg extract (27.69±1.14%) were found. The results of this study provide support for the traditional therapeutic value and the reported antimalarial activity.
