The properties of coelacanth, Latimeria chalumnae, oil were studied. Fatty acid composition of coelacanth oil was analyzed by gas-liquid chromatograph using a hydrogen ionization detector on a DEGS column.
The general fatty acid composition was as follows; saturated fatty acids 19.0% (C₁₀: 0.2%, C₁₂: 0.2%, C₁₃: 0.8%, C₁₄: 2.7%, C₁₅: 0.7%, C₁₆: 10.6%, C₁₈: 2.9%, C₁₉: 0.9%), and unsaturated fatty acids 81.0% (C_10-1: 0.1%, C_12-1: 0.1%, C_14-1: 1.2%, C_14-2: 1.0%, C_16-1: 4.9%, C_16-2: 0.9%, C_16-3: 0.8%, C_18-1: 24.4%, C_18-2: 1.4%, C_18-3: 1.1%, C_18-4: 2.9%, C_20-1: 3.5%, C_20-2: 1.5%, C_20-4: 1.9%, C_20-5: 8.1%, C_22-1: 3.2%, C_22-5: 4.6%, C_22-6: 19.4%).
The most prominent was monoenoic C₁₈ acid 23.4%, followed by hexaenoic C₂₂, acid 20.4%, saturated C₁₆ acid 10.6% and pentaenoic C₂₀ acid 8.1%.
