Rapid semi-quantitative spot test for determination of thebaine and differentiation of Papaver bracteatum from P. orientale and P. pseudo-orientale.
The alkaloids, orientalidine, oripavine, thebaine, narceine, narceine, codeine, papaverine, isothebaine, alpenigenine and morphine react with a solution of sulfuric acid containing molybdate to give specific colors. Using the acid solution permitted the differentiation of Papaver bracteatum latex from P. orientale latex and P. pseudo-orientale latex.
