Abstract
The fatty acid compositions of the lipids of two holothurian species ( Cucumaria japonica and C. okhotensis) were investigated. High contents of 12-methyltetradecanoic acid and eicosapentaenoic acid (up to 17.7 % and 28.4% of total fatty acids, respectively) in the lipids of both species were revealed. Species specific differences in the content of 23:1 n-9 fatty acid in the lipids from viscera and body wall were found. In C. japonica, the viscera to body wall ratio was 0.07, while in C. okhotensis this ratio was 0.28. The fatty acid compositions of the lipids from both investigated holothurian species permit their use for the manufacturing of foodstuff, as well as for biologically active additives.
