Abstract
Simple and rapid thin-layer chromatographic methods have been used to investigate the catecholamine metabolites present in the urine of sick children. A semi-quantitative method for 4-hydroxy-3-methoxy-mandelic acid (HMMA) has been devised and compared with the quantitative spectrophotometric procedure. The methods have been performed on both normal subjects and children with catecholamine-secreting tumours, without dietary restriction, and have led to a 50% reduction in the number of samples requiring laborious quantitative determination of HMMA excretion.
