The chemical composition of the oil collected in the second trap was investigated by GC–MS. The GC–MS traces were characterized by the dominant presence of hydrocarbons, that included phytadienes, phytene and pristene from the thermal cracking of chlorophyll, while an unresolved complex mixture (UCM) in the range of C15–C30 peaked by n-alkenes/n-alkanes probably derived from the thermal cracking of triterpenoids and algaenans ( Nguyen et al., 2003).
