Two lignan glucosides, the known tracheloside and the new carthamoside, together with their two known aglycones, trachelogenin and (7E,8'S)-7,8-didehydroarctigenin (cf. cartha- mogenin), were isolated from the seeds of Leuzea carthamoides. Additional four phenylpropanoid derivatives of tryptamine, the E and Z isomers of N-feruloylserotonin and N-isoferuloylserotonin, were also isolated and identified. Their structure determination and identification were performed by spectroscopic, mainly NMR analysis.
