Alkaloids fromGalipea officinalis

Abstract
Galipea officinalis Hancock is a shrubby tree reputed in folk medicine for its many properties which may be related to its alkaloid composition. We present in this paper the structural elucidation of five quinoline alkaloids: cuspareine, cusparine, and galipine, that have been previously described, demethoxycusparine, newly isolated in this species of Galipea and a new quinoline alkaloid named galipinine which is the 3′,4′-methylenedioxycuspareine.
