Abstract: The characteristics of petroporphyrin biomarkers in Xixiepo oil has been investigated by UV-Vis, MS and HPLC techniques. The UV-Vis spectrum showed that most of the petroporphyrins in this area are nickel derivatives. The MS results on the analysis of the crude oil showed that there are six types of porphyrin at least as follows: ETIO, DPEP, Di-DPEP, Rhodo-ETIO, Rhodo-DPEP and Rhodo-Di-DPEP, and the ratio of DPEP to ETIO 0.33 illustrates the higher oil maturity.

Key words: biomarker, petroporphyrin, UV-Vis, MS, HPLC
