Abstract

Aim of the study: The in vitro antiplasmodial activity and cytotoxicity of methanolic and dichloromethane extracts from five Congolese plants were evaluated. The plants were selected following an ethnobotanical survey conducted in D.R. Congo and focusing on plants used traditionally to treat malaria. The in vivo antimalarial activity of aqueous and methanolic extracts active in vitro was also determined in mice infected by Plasmodium berghei berghei. Materials and methods: The growth inhibition of Plasmodiumfalciparum strains was evaluated using the measurement of lactate dehydrogenase activity. The extracts (aqueous, CH₃OH, EtOH and CH₂Cl₂) were prepared by maceration and tested in vitro against the 3D7 (chloroquine sensitive) and W2 (chloroquine resistant) strains of Plasmodiumfalciparum and against the human normal fetal lung fibroblasts WI-38 to determine the selectivity index. Some extracts were also used at the dose of 300 mg/kg to evaluate their activity in mice infected since 4 days by Plasmodium berghei. Results: Two plants presented a very high activity (IC₅₀ < 3 μg/ml). These plants were Strychnos icaja roots bark (MeOH and CH₂Cl₂) and Physalis angulata leaves (MeOH and CH₂Cl₂). One plant (Anisopappus chinensis whole plant, MeOH and CH₂Cl₂) presented a high activity (IC50 < 15 μg/ml). The extracts of Anisopappus chinensis and Physalis angulata showed also a good inhibition of parasitemia in vivo. Flavonoids, phenolic acids and terpenes were identified in these plants by a general phytochemical screening method. Conclusion: Three plants showed a very interesting antiplasmodial activity (Anisopappus chinensis, Physalis angulata and Strychnos icaja) and one of them showed a good selectivity index (>10, Anisopappus chinensis). Anisopappus chinensis and Physalis angulata were also active in vivo.
