    Non-aqueous, reversed-phase, high-performance, thin-layer chromatography and column liquid chromatography of metal complexes of porphine (1986)

    Notes: Summary The chromatographic mobility of 21H, 23H-porphine and its Ni(II), Cu(II), Zn(II) and Pd(II) complexes were investigated by high-performance thin-layer chromatography on an octadecyl-bonded, silica gel plate with various polar organic solvents including alcohols, acetonitrile, dimethylsulfoxide and propylenecarbonate. The mobility generally decreases according to the central metal ion of the complex as follows: Zn(II)〉(free porphine)〉Ni(II)〉Pd(II)〉Cu(II). Methanol is a good choice of solvent for the separation of these metal porphine complexes. Successful separation of porphine and the four metal complexes is accomplished within 13 min on a LiChrosorb RP-18 column with methanol eluent.

    High-performance thin-layer chromatography of etioporphyrin and its vanadium (IV), nickel (II) and coper (II) complexes (1985)
    Springer
    Chromatographia 20 (1985), S. 417-420

    ISSN: 1612-1112

    Topics: Chemistry and Pharmacology
    Notes: Summary The RF values were obtained for etioporphyrin I (H2Etio) and its vanadyl, nickel and copper complexes on cellulose, silica gel, and octyl-bonded silica HPTLC plates, with various organic solvents. The mobility of these compounds tends to increase in the following order: (1) on cellulose, VOEtio 〈 H2Etio 〈 CuEtio ≤ NiEtio; (2) on silica gel, H2Etio 〈 VOEtio 〈 NiEtio ≤ CuEtio; (3) on octyl-bonded silica, CuEtio 〈 NiEtio 〈 VOEtio and the apparent mobility of H2Etio relative to metal-Etio complexes depends on the developing solvent used. Complete separation of these four Etio compounds can be accomplished on an octyl-bonded silica plate with either methanol or acetone.
