A racem. 8,14-dihydroamurine is a new promorphinane alkaloid isolated from the aerial parts of Papaver nudicaule L. (Papaveraceae) of Mongolian origin. The known promorphinane and isopavine alkaloids (+)-amurine, (-)-amurensinine, (-)-O-methylthalisopavine, (-)-flavinantine and (-)-amurensine were also described. All structures were established by physical and spectral analysis. Flavinantine has been found for the first time in the species.
