NMR and GC-MS analysis of fractions of the CHCl3 extract of Trichilia catigua bark led to the identification of a mixture of three omega-phenyl alkanes, three omega-phenyl alkanoic acids, five omega-phenyl-gamma-lactones, two alkyl-gamma-lactones, one alkenyl-gamma-lactone and a mixture of fatty acids ranging from C-14 to C-26.
