The alkaloids from the epigeal part of the wild blackspot horn poppy have been studied. Twelve alkaloids have been isolated of which one - norbracteoline - proved to be new. Its structure has been established. Dehydrocorydine, predicentrine, glaufidine, thalicmidine, reticuline, and stylopine α-methohydroxide have been isolated from this plant for the first time. © 1984 Plenum Publishing Corporation.
