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