All major fragment ions of codeine and morphine were elucidated using LC–electrospray MS/MS and high resolution FT-ICR-MS combined with an IRMPD system. Nanogram quantities of labeled codeine were isolated and purified from Papaver somniferum seedlings, which were grown for up to 9 days in the presence of [ring-13C6]-l-tyrosine, [ring-13C6]-tyramine and [1,2-13C2], [6-O-methyl 13C]-(R,S)-coclaurine. The labeling degree of codeine up to 57% into morphinans was observed.
