Abstract
High-resolution spectrofluorimetry (HFR) at 4.2/sup 0/K in n-alkane matrices is reported as a method for the identification of polycyclic aromatic hydrocarbons (PAH) derived from triterpene, which occurs in the orgainic matter of marine and terrestrial sediments. The marine sediments studied were cored from the Sea of Oman at water depths varying between 200 and 4000 m in an area where the organic matter is mainly of authochthonous origin. The series of chrysene derivatives were extracted from the total aromatic fraction by high performance liquid chromatography on ..mu..-silica-NH/sub 2/ stationary phase with n-heptane as an elutant.
