Cod liver oil fatty acids as secondary reference standards in the GLC of polyunsaturated fatty acids of animal origin: analysis of a dermal oil of the atlantic leatherback turtle

The use of the esters of whole cod liver oil fatty acids as secondary standards in the GLC identification of animal polyunsaturated fatty acids is feasible. This technique is exemplified by an analysis on several polyester substrates of the component fatty acids of a somewhat unusual marine‐type oil from the Atlantic Leatherback turtle Dermochelys coriacea coriacea (Linnȳ) , with provisional identifications of minor components through the linear log plot and separation factor procedures.
