It comprises of a two column system, one for the analysis of the biogenic amines and one for the metabolites. The preparation of brain samples for analysis has been made as simple as possible (homogenisation in perchloric acid, plus centrifugation) so that all the compounds of interest are present in the sample. The biochemical action of oxypertine has been assessed using the above system. Comparing the action of oxypertine against the action of reserpine has shown a difference between the two compounds. Reserpine causes at least 90% reduction in neuronal amine content while oxypertine caused no reduction in neuronal amine content.
