A large number of opium alkaloids has been chromatographed by gas, thin-layer, and paper chromatography for the purpose of identification. Gas chromatography is particularly valuable because of its speed, sim licity, and reproducibility. T h e two other methods are useful for certain alkaloi& which

produccs a curved segment a t lower pH values.8 In calculating the purity and ionization constant, only the linear portion of each plot was used. Nevertheless, it may be seen (Table 11) that the intercept obtained (and therefore the purity evaluated) is not markedly influenced by the choice of activ
A thin-layer chromatographic procedure is described for the qualitative identification of several antihypertensive drugs including certain thiazide diuretics, spironolactone, triamterene, methyldopa and their metabolites. Utilization of new solvent developing systems and spray detecting reagents pro
It was the object of the present'study to develop a quick and reliable method for the detection of the psychotropic drugs, based on their chromatographic and chromogenic behavior. The group investigated includes commonly used psychotropic agents with different chemical structure and pharmacological
