Characteristics of UV VIS MASS HPLC of Petroporphyrin Biomarkers;

In this paper, the properties of petroporphyrins, the techniques of isolation, purification and identification of petroporphyrins were reviewed in detail.

This review summerizes petroporphyrin synthesis, and deals mainly with the preparation of porphyrins tearing five - membered exocyclic rings: Deoxophylloervthro - etioporphyrin (DPEP) .

Synthesis and Characterization of 5-(4-benzyloxylphenyl) -10,15,20-triphenylporphyrine and Its Ruthenium (Ⅱ) Complex;

Rare earth porphyrine complex,praeseodynium-porphyrine,is synthesized by solid state reaction,and electronic absorption spectra of porphyrine and praeseodynium-porphyrine is studied.

ased on the formation of the complexof Zn(Ⅱ)with meso-tetrakis(4-trimethy-lammonium phenyl)porphine in the pres-ence of ethylene-diamine, a new spectropho-tometric method for the determination oftrace Zn (Ⅱ)has been developed,The ab-sorption maximum of the complex is at425nm and its apparent molar absorptlvity is3.

In this paper,the color reaction of Cadmium(Ⅱ)witha, β,γ,δ-tetra(3-methoxy-4-hydroxyphenyl)porphine(T(3-M-4-HP)P)is studied.
