A Simple and Rapid Method for Estimating 3,4-Dihydroxyphenethylamine (Dopamine), 3,4-Dihydroxyphenylalanine (Dopa), and Homovanillic Acid (HVA) with "Two-Solutions Paper Electrophoresis"

[摘要] An easy procedure for the estimation of 3,4-dihydroxyphenylalanine (dopa), 3,4-dihy-droxyphenethylamine (dopamine), and homovanillic acid (HVA), besides 3-methoxy-4-hydroxymandelic acid (VMA), by means of the "two solutions paper electrophoresis" (1) is described. Increased amounts of these phenolic compounds were found by this method in the urine of a patient with neuroblastoma, and the case report is presented.
