The mixture of alkaloids in the seeds of Ormosia jamaicensis Urb contains piptamine (C20H35N3), angustifoline (C15H24N2O), and three new bases ormojanine (C20H31N3), ormosajine (C20H33N3), and ormojine (C20H33N3). The relationships of these bases to alkaloids in Piptanthus nanus and in other Ormosia species is discussed. Two other minor alkaloids have been shown to be present in the mixture of bases.
