The authors are working on the liver oils of edible crabs in the Northern Ocean of Japan. In the present work α-alkyl glyceryl ethers and cholesterol were found in the solid from the unsaponifiables of the liver-oils of Chionoecetes opilio (Zuwai-kani) and Lithodes turritus (Ibara-kani). Two kinds of crystalline materials were isolated from the solid part of unsaponifiables by the fractional crystallization from methanol. One of them was identified as cholesterol by means of IR, NMR and mass spectroscopies. The other was confirmed to be the mixture of α-alkyl glyceryl ethers from the results of IR and NMR analyses. Then they were separated through GLC into C8C20 α-alkyl glyceryl ethers. The major components were α-n-hexadecyl and α-n-octadecyl glyceryl ethers. Their contents were respectively 69.0% (C. opilio), 59.0% (L. turritus) and 19.7% (C. opilio), 35.2%. (L. turritus).
