Meconopsis rudis

Slavik isolated, the alkaloid MR-1 from Meconopsis rudis Prain. It is an N-methyltetrahydronorharmane (6-methoxy-2-methyl-l,2,3,4-tetrahydro-j8-carboline) (210) (221). 

Formerly, rhoeadine and papaverrubine alkaloids were known to occur only in the plants of the genus Papaver. Recently, Slavik et al. have shown that rhoeadine and papaverrubine E are present in Bocconia frutescens and papaverrubine D in Meconopsis betonicifolia, M. horridula, M. napaulensis, M. paniculata, M. robusta, M. rudis, and M. sinuata (33, 50). The genus Meconopsis is botanically closely related to the genus Papaver, a relation thus confirmed chemotaxonomically (see structures 152-154 in Table V).
