An efcient system for the analysis of the total alkaloids extracted from leaves of Mitragyna inermis (Willd.) O. Kuntze (Rubiaceae) by HPLC using a reversed‐phase column is described. The chromatographic conditions allowed the separation of indole and oxindole alkaloids in leaf extracts, and the quantication of uncarine D in samples collected in Burkina Faso and Mali. The HPLC method described was validated for its specicity, linearity and precision using an internal standard (naphthalene). The concentrations of uncarine D in various extracts were compared with their in vitro anti‐plasmodial activity. The anti‐proliferative activity on chloroquine‐resistant strain (W 2 ) of Plasmodium falciparum was not correlated with the concentration of uncarine D in leaves.
