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. carthamogenin), were isolated from the seeds of Leuzea carthamoides. Additional four phenyl-propanoid 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.

The title compounds were obtained by α-hydroxylation of the corresponding α,β-dibenzyl-γ-butyrolactones (lignans of synthetic origin), and were correlated to (+/-)-methyltrachelogenin 9 whose relative structure was definitely established by X-ray cristallography. (-)-Trachelogenin 1 and (-)-nortrachelogenin 12 thus have the (8S,8'S) absolute configuration, whereas (+)-nortrachelogenin 20 (or wikstromol) has the (8R,8'R) absolute configuration.

Lignans of Trachelospermum asiaticum were isolated from the polar fraction of the methanol percolate, and the structures were determined.Trachelosiaside (matairesinol 5'-C-β-D-glucoside) was isolated as the first naturally occurring C-glucoside of lignan.
