Reported in this paper are the composition and distribution of alkyl cyclopentanes, alkyl cyclohexanes, linear alkylbenzenes and phenylalkanes in the seep carbonate from AC 645(Sample AC-E) at the lower slope of Gulf of Mexico, where the water depth is 2 200 m. The distribution of alkyl cyclopentanes and alkyl cyclohexanes is similar to normal alkanes, which are dominated by low molecular weight compounds and maximized at C₁₄, C₁₅, respectively,  suggesting that the alkyl cyclopentanes and alkyl cyclohexanes are mainly originated from bacteria and phytoplankton.
