Abstract Alpinine, epialpinine, muramine and protopine were identified as alkaloids of Papaver bracteatum . The earlier reported presence of alpinine is revised. The structures of codeine and neopine, earlier reported for this species, are assessed. Screening for the presence of O -methylflavinantine was negative.
