A TLC method for the simultaneous analysis of vanillylmandelic, homovanillic and 5-hydroxyindole-3-acetic acids in urine is described. The sample is cleaned up through a cyano minicolumn and extracted with diethyl ether. The acids are resolved by high-performance TLC, visualized by Folin Ciocalteau

The biomedically and neurochemically important compounds 5-hydroxyindoleacetic acid (5-HIAA) and homovanillic acid (HVA) have been simultaneously determined in human urine after reverse-phase two-dimensional high-performance liquid chromatography. A 10-fold-diluted urine sample (20 microliters) is f
