Abstract
It has been previously suggested that porphyrins are derived from chlorophyll. New geoporphyrins have been separated from samples collected from Siberia and Uzbekistan whose PMR spectra show the existance of two isomers; a predominant one derived from chlorophyll c and trace amounts of one derived from chlorophyll a. -A.W.Hall
