Biological Activities
Compounds
Alstonia congensis is a plant species widely recognized for its traditional use in treating various ailments, including malaria, across several African countries. Scientific investigations into its root bark have revealed that the plant contains several significant indole alkaloids. Specifically, Alstonia congensis contains boonein, an isolated constituent that was found to be inactive against certain strains of P. falciparum in vitro. Additionally, Alstonia congensis contains echitamine, which exhibited moderate antiplasmodial activity against both chloroquine-resistant and chloroquine-sensitive strains. These findings suggest that the complex chemical profile of the plant contributes to its potential as a raw material for developing malaria remedies.
Conditions
Alstonia congensis is recognized for its medicinal value in treating malaria, a role supported by ethnobotanical surveys and scientific studies. The plant has demonstrated efficacy in treating COVID-19-related symptoms, emerging as one of the most commonly cited species in Gabonese traditional medicine. Research confirms its ability to treat the chloroquine-resistant strain P. yoelii N67 through effective in vivo chemosuppression. Furthermore, extracts of the root bark are capable of treating the chloroquine-resistant strain Plasmodium falciparum K1 in vitro. Finally, the plant also shows antiplasmodial activity against the chloroquine-sensitive strain P. berghei berghei ANKA.
