Alstonia constricta
Arbre australien avec une berceuse amère utilisée par les peuples autochtones australiens et les premiers colonisateurs comme substitut de la quinine contre le paludisme.
Alstonia constricta, commonly known as quinine bush, is a traditional Australian medicinal tree whose bark has been used as a substitute for quinine in treating malaria. Its primary active compounds include the indole alkaloid alstonine and porphyrine, along with other alkaloids and tannins, which contribute to its antimalarial, antipyretic, and analgesic properties.
Alstonine exhibits antimalarial activity by inhibiting heme polymerization, similar to chloroquine, and may also modulate GABA-A receptors, contributing to its sedative and anxiolytic effects. The alkaloids in Alstonia constricta have been shown to possess anti-inflammatory and analgesic actions through inhibition of cyclooxygenase and lipoxygenase pathways. Additionally, the plant's hypotensive effects are likely due to vasodilation mediated by alkaloid-induced nitric oxide release.
