In this paper the content of hydrocarbon contained in the liver oil of various deep sea sharks is reported except those species studied previously.
Although most species examined for the present study have been found with amounts of hydrocarbon, there were exceptions of species or individuals whose liver oils scarcely contained hydrocarbon. They were sample shark No.8, Pseudotriakis acrages and some of Scymnodon squamulosus.
Referring to the liver oil obtained from all the samples examined so far the relationships of the hydrocarbon content with either of specific gravity (1), refractive index (2) and the unsaponfiable matter content (3) are expressed by the following equations, respectively;
x=1773.2-1960 t₁……………(1) (Fig.1)
x=3418.8t₂-4991.9……………(2) (Fig.2)
x=1.266t₃-28.7……………(3) (Fig.3)
where x is the hydrocarbon content in the liver oil (%)
t₁, specific gravity (d_??_) of the liver oil
t₂, refractive index (n_??_) of the liver oil
t₃, unsaponifiable matter in the liver oil (%).
