H. Hori et al., HIGH-PERFORMANCE LIQUID-CHROMATOGRAPHIC ISOLATION AND CHARACTERIZATION OF (PHEOPHYTIN)MERCURY(II), Journal of liquid chromatography, 18(4), 1995, pp. 779-789
Mercury-substituted chlorophylls, i.e., (pheophytin a)mercury(II) and
(pheophytin b)mercury(II), were separated by reversed-phase HPLC with
a C-18-bonded silica column and a mobile phase of acetone-methanol. Th
eir spectroscopic and chromatographic characteristics strongly suggest
that both (pheophytin a)mercury(II) and (pheophytin b)mercury(II) for
m 1:1 (metal ion:chlorin ring) complexes.
