Triclisia dictyophylla

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...

In this connection it is of interest to note that Menispermaceae are also components of African arrow poisons The roots of Triclisia dictyophylla Diels (T. gilletii (De Wild.) Staner) are reported to be used in the southwestern part of the Central African Republic (348). Phaeanthine (20h) and the bis-quaternary iV,iV -dimethylphaeanthine (20i) are both present in the plant. In rabbits and rats, the latter base appears to have about one-tenth of the activity of (-h)-tubocurarine (349) it seems unlikely that it will contribute much to the over-all effect of the arrow poison, which therefore cannot be classed as a curare.
