The differences between ternary and binary solvent system used for high performance liquid chromatographic (HPLC) analysis of metal-free geoporphyrins have been investigated, and shown that the ternary solvent system can not be equally treated as a binary one. A set of analytical conditions of binary solvent system analysis of complex mixture of metal-free geoporphyrins are set up. By varying the amount of both acetic acid and pyridine to the mobile phase, efficient separation can be achieved on lower efficience normal phase column through utilizing a proper stepped programme. By making a comparision between MS to HPLC of some typical samples, the HPLC peak groups of ETIO, DPEP and Di-DPEP are tentatively assigned, when the volume ratio of solvent mixtures used are: (A) hexane-methylene chloride-acetone-pyridine (500: 200: 50: 1.5), (B) hexane-acetic acid (105: 1). |
