SUMMARY Pure pheophytins a and b and pheophorbide a were isolated and the metal complexes of these compounds prepared in pure solutions. The metal content showed a 1:1 ratio of metal to pheophytin or pheophorbide. The spectral curves of the pure complexes were prepared and tables of absorptivities calculated. The molar absorptivities of the pheophytin a and pheophorbide a complexes proved identical.
