Uroporphyrins I and III have been separated by high performance liquid chromatography on a microporasil column using n-heptane:glacial acetic acid:acetone:water (90:60:30:0.05 by volume). By using uro [3H]porphyrin I and uro[14C]porphyrin III it was shown that less than 2% cross contamination occurred during the chromatographic separation. The same system may be used to separate uro through protoporphyrins (as their esters) by simply increasing the acetone concentration.
