Alkylbenzene, normal alkanes and alkylcyclohexane on the pyrolysates of P. Boryanum at 300℃ had uniform distribution and the relative content of them was similar, indicating that they originated from same precursors. Fatty acids, alcohol and ketone in algal cell are the possible precursors. For example, the precursor of relatively abundant C〓 alkylbenzene and alkylbenzene with C〓 side chain perhaps related with palmitic acid.
