Two quaternary alkaloids have been isolated from the root barks of STRYCHNOS VARIABILIS collected in Zaire. The structure of these alkaloids (mavacurine and fluorocurine) could be deduced from spectral data: UV, MS, IR and (1)H NMR. Moreover, the stereochemistry could be assigned by (1)H NMR at 360 MHz.
