Peinamine, a new bisbenzylisoquinoline alkaloid from arrow tips (pei-namô) of the Upper Orinoco.
A new bisbenzylisoquinoline alkaloid has been isolated from a curare of the Upper Orinoco region. The curare is made by Indians from an unknown plant (probably Menispermacea) and is kept on arrow tips. The structure of the alkaloid, named peinamine, has been elucidated on the basis of its chemical reactions and spectroscopic data (N.M.R., M.S. and O.R.D.).
