The phospholipids of mussels (Mytilus edulisl Linne) from the coast of Qingdao were extracted, fractionated and analysed over a 12 month period. Thecontents of total lipids, neutral lipids, polar lipids and phospholipids were meausred. The composition of phosholipids was determined by high-performance liquid chromatiorgraphy, and their fatty acid composition was analysed by gas chromatorgraphy. Thephospholipide contert ranged from 3.6 to 6.4 g kg-1 soft tissue. Pe (phosphatidyl ethanlaminc) and PC (phosphatidyl chline) were the major constituents. C16:0, C20:5 and C22:6 wree the major fatty acids. C20:5 (5.25-23.10%) and C22:6 (6.05-20.42%) varied regularyly with the seasonal factors, Their total amounts were high from January to Juhne, which wouldbe an optimal time for the utilisation of trhe phospholipids of mussels.
