Porphyrins and phycobilins in Precambrian rocks
Samples of Precambrian rocks (1.7–2.6 billion years, U.S.S.R.) contain metalloporphyrins and linear tetrapyrrole pigment similar to phycobilin 655 from modern blue-green algae Microcystis (according to data of...

Metalloporphyrins and molecular complexes of amino acids with porphyrins in juvenile volcanic ash
In samples of juvenile ash of the volcano Tjatja, USSR (that erupted in 1973) metalloporphyrins were found. With respect to the fluorescence spectra free bases of the compounds were close to the pigments that ...
