The content and composition of alkyl glyceryl ethers of liver lipids of gonatid squid Berryteuthis magister in the Sea of Japan were investigated.Weight of the livers of thirty-four specimens of this species accounted for 9.0±1.8% of total body weight; 23.8±9.1% of the liver was lipids. The liver lipids contained high quantities of unsaponifiables (26.7±4.0%), consisting of 55.2±11.4% alkyl glyceryl ethers and 41.9±11.7% sterols. Alkyl glyceryl ethers and sterols originated from diacyl glyceryl ethers (27.5±9.0%) and steryl esters (12.0±5.6%), respectively. The relationship between the amount (Y, g) of alkyl glyceryl ethers of liver and liver weight (X, g) was expressed by the following equation: Y=-0.556+0.077X, (r=0.961, P〈0.05).The component alkyl glyceryl ethers were found to consist mostly of saturates (69.8±4.9%) and monoenes (27.4±4.7%) of 14-20 carbon numbers for the alkyl moiety. The principal components found were: chimyl (16:0, 58.7±6.4%), selachyl (18:1, 24.6±4.6%), and batyl (18:0, 6.6±1.9%) alcohols. This indicated that the liver of the gonatid squid species was a good source of alkyl glyceryl ethers having chimyl alcohol as its predominant component.
