Abstract
Ten cultured and three wild yellowtails were obtained from ten water regions of Japan within 48 hours after catching. Various tissues were separated from the fish, and the content of tocopherol (Toc) was analyzed using high performance liquid chromatography. The contents of vitamin A and D in the muscle tissue and liver were also analyzed by the same technique.
1) The content of Toc in a tissue of yellowtail varied by individuals, but had a tendency to increase with growth of the fish. The content of Toc in common muscle or liver was significantly correlated with the body length. In general, the content of Toc in liver was higher than that in any of the other tissues.
2) The content of Toc was significantly correlated with the lipid content in the muscle tissue and liver, and was higher in the fatty tissue than in other tissues.
3) In the muscle tissue and liver of yellowtail, the content of Toc was correlated with the content of vitamin A, but poorly correlated with the content of vitamin D.
