The quantitative compositions of fatty scids in the blubber oils and head oils of Tursiops sp. (Hando Iruka), Pseudorca sp. (Okigondo Kuzira) and Grampus sp. (Hanagondo Kuzira) were determined (Table 7a, 7b and 7c). In this analysis, fatty acids were previously fractionated to the liquid and solid acids by the Urea adduct-MeOH method1) before fractional distillations (Table 2a, 2b and 2c). After the fractional distillations, the number of double bond of the methyl ester of unsaturated fatty acids were estimated by the paper chromatography of their mercuric compounds²). On the fatty acids of their blubber oils, the saturated and unsaturated acids were about 20% and 80% respectively, and about 80% of them are C₁₆, C₁₈ and C₂₀ acids. On the Pseudorca sp. and Grampus sp,, the fatty acids of C₁₆ dominate (about 40%), and on Tursiops sp. the fatty acids of C₁₈ are main part (about 34%). The saturated fatty acids of their head oils are about 75% of Tursiops sp. and Pseudorca sp., but are 52% of Grampus sp., and the unsaturated fatty acids of one double bond are about 20% of the former and about 50% of the latter. The saturated fatty alcohols are about 92% of the unsaponifiable matter and 85% of them is hexadecanol in the head oil of Pseudorca sp. (Table 9).
