The quantitative composition of fatty alcohols in the blubber oil of a pacific beaked whale, Berardius bairdii, was determined (Table 6). In this analysis, alcohols were previously fractionated before fractional distillation by the Urea adduct-Me OH method3)4) (unsaponifiable matter: urea: solvent=1:2:20), which was very effective to separate octadecenol (Tables 3 and 6). The saturated and unsaturated alcohols were found to be 38% and 62% respectively, and the latter is almost entirely consisted of monoethenoid alcohols by the oxidation method with KMnO4 in acetone solution. The fatty alcohols are mainly composed of octadecenol (53%) and octadecanol (27%), and the presence of such a large quantity of octadecanol has not been so far reported on marine animal oils.
