Popis: The new aporphine-benzylisquinoline khyberine ( 4b ) is present in Berberis calliobotrys Aitch. ex Bienert in about one part per million. An effort is made to present a complete scheme for the biogenesis of aporphine-benylisoquinoline dimers which arise from the condensation of two coclaurine units.
