Slavik (380) was the first to isolate mecambroline (1,2-methylene-dioxy-10-hydroxyaporphine) from Meconopsis cambrica. It has hypotensive effects upon mice and rabbits (393). The question of the structure-activity relationships between the pharmacological actions of this alkaloid and aporheine has been discussed (393). [Pg.226]

Codeine, 14-hydroxycodeine, neopine, and O-methylflavinantine have been isolated from Papaver bracteatum,146 flavinantine and amurine from Meconopsis cambrica,113 isosinoacutine from Stephania elegans,174 and a new alkaloid, tridictyophylline, for which the structure (96) was determined by X-ray crystallography, from Triclisia dictyophylla.175 Bound morphine, codeine, and thebaine have been found in P. bracteatum and P. somniferum,176 and the effect of the period of maturation of the plants on the yield of these three alkaloids from P. somniferum has been studied.177,178 Codeine has been isolated from cell suspension cultures of P. somniferum under conditions where no morphine, norcodeine, or thebaine could be detected.179... [Pg.119]

Meconopsis comprises some 40 species which are mainly indigenous to China and the Himalayas. Protopine (3), protoberberine (5), benzophenanthridine (6), isopavine (13) and aporphine alkaloids (Fig. 2) have been isolated from a small number of species. Rhoeadine alkaloids, which are present in Papaver species, also occur in Meconopsis and their distribution appears to be limited to these two genera (Slavik and Slavikova 1977). The sole European representative, M. cambrica growing in England produces magnoflorine (4) as the major alkaloid, together with protoberberine (5), proaporphine (14) and promorphinan alkaloids (15) (Hemingway et al. 1981). [Pg.35]
