摘　　要：地质体物质中卟啉的检出以及由叶绿素到石油卟啉演化模式的提出，增加了研究这些化石色素作为生物标志化合物的兴趣。研究表明，从原油、页岩、煤和沥青中分离的石油卟啉，主要是由脱氧叶红初卟啉(DPEP)和初卟啉(Aetio)的镍、钒络合物组成。Reported in this paper are the preliminary results of the study of petroporphyrins in Guang-33 crude ail from a gypsum-salt environment in the Jianghan salt-lake basin, China. Absorption spectrophotometric, high performance liquid chromatographic (HPLC) and mass spectrometric studies have shown that the porphyrins in the crude oil consist mostly of nickel deoxophylloerythroetioporphyrins. Both high performance liquid chromatographic and mass spectrometrie analyses have confirmed that their di-stribution is characterized by the C29-C33 DPEP-type porphyrin homologous series with the maxium at C31. In HPLC determination a new porphyrin component, C32-DPEP with a six-membered isocyclic ring (C31 D-6) has also been identified by using a new solvent system and co-injecting synthetic standard sample.
