After the isolation of an alkaloid from Papaver somniferum L. var. nigrum, its structure was determined by means of IR, UV and 1 H and 13 C-NMR spectroscopy, and MS, together with a selective O-methylation assay. The alkaloid was identified as 6,7,8,14-tetrahydro-4,5-epoxy-6-methoxy-17-methyl morphi
