Abstract:
The fatty acid (FA) composition of total lipids isolated from the marine sponge Halichondria panicea inhabiting Peter the Great Bay of Sea of Japan was studied. GC and GC-MS techniques helped identify 63 FAs, with the main attention being paid to FAs with 14-22 carbon atoms. 4, 8, 12-Trimethyl-13:0 FA was for the first time identified as the main saturated FA along with the branched FAs br-25:1, br-27:1, and br-27:2. The contents of arachidonic, eicosapentaenoic, docosapentaenoic, and the major demospongic acids [26:3(5, 9, 19), 26:3(5, 9, 17), 27:3(5, 9, 20), and 28:3(5, 9, 21)] considerably differed from those previously found for H. panicea, which may be due to seasonal changes in the species composition of organisms consumed by the sponge.
