Himbadine is a piperidine alkaloid with a polycyclic scaffold first isolated from Galbulimima sp. a magnolia species native to northern Australia and South East Asia, and reported in 1967 by Ritchie and co-workers, University of Sydney, Australia. The bioactivity of Himbadine has not been extensively investigated but its close structural relationship to other Galbulimima alkaloids suggests a possible affinity for muscarinic receptors.
