Popis: Sixteen alkaloid compounds were isolated from the dried rhizomes of P. zanlanscianense, including a pair of new enantiomers (R/S)-7'-ethoxy-trans-p-couma-royltyramine (1a/1b) and 14 known compounds (2-14) isolated from this plant for the first time. The structures of new compounds were identified by IR, NMR and MS spectroscopic analysis, and their absolute configurations were determined by comparison of the experimental and calculated ECD data.
