Abstract

The alkaloid pattern of the endemic plant Papaver coreanum Nakai (Papaveraceae) was determined for the first time. Eight alkaloids could be identified by LC/ESI-MS/MS and high-resolution mass spectrometry. Among them, protopine and allocryptopine represent the main components. Besides norsanguinarine, sanguinarine, dihydrosanguinarine, oxysanguinarine, lincangenine, and cryptopine, some other trace alkaloids were found whose structures remain unknown.
