Summary

The thin-layer chromatographic mobility of hematoporphyrin IX (Hp) and its metal complexes on octyl (C8)- or octadecyl (C18)-bonded silica gel plate is described. The mobility order for those compounds is regular on both kinds of plate with various compositions of methanol-phosphate buffer mixtures as the developing solvents; thus, Cu-complex < Ni-complex < Hp (free acid) < Zn-complex. The combination of a C18-plate with an 85∶15 (vol/vol) mixture of methanol and phosphate buffer (pH 3) is recommended for the successful separation of these four compounds.
