 Title    Phosphonolipids in the Mussel Mytilus galloprovincialis  
 Abstract    One of the possible roles of phosphonolipids is that they have a contribution to the protec­ tion of cellular integrity and survival of aquatic organisms (mollusca, cnidaria) as these lipids are included at high percentages. The total lipids of the edible mussel Mytilus galloprovin­ cialis (Mollusca, Bivalvia, M ytilidae) were found to constitute 1.27% of fresh tissue. Polar lipid com ponents constitute 61.5% of the total lipids. After separation by Solid Phase Extrac­ tion, the polar lipid fraction was separated by two dimensional thin-layer chromatography and the total phosphorus of each component, was determined. The main polar lipids found were: Phosphatidylcholine, 41.6 ± 0.8% (of which 11.3 ± 0.5% was glyceryl ether analog); ceramide am inoethylphosphonate 11.2 ± 0.2% plus 2.8 ± 0.1% another minor species; phos-phatidylethanolamine, 26.6 ± 0.5% (of which 12.2 ± 0.3% was glyceryl ether analog). The individual ceramide aminoethylphosphonate species were isolated by preparative thin layer chromatography and the structure of the major one was confirmed by a combination of analytical and chromatographic methods. Saturated fatty acyl groups with 16 carbon atoms were the main com ponents (48.4%) of the major ceramide aminoethylphosphonate species. Diglyceride aminoethyl phosphonates were not found in lipids of M. galloprovincialis.

 Title    Analysis of the Seed Lipids of Aleurites montana  
 Abstract    The seed lipids of the Chinese tung-oil tree Aleurites montana are composed of 97.2% triglycerides, 2% phospholipids and of 0.8% glycolipids. In the triglycerides 67% of all fatty acids are a-eleostearic acid (configuration C 18:3, A9 cis, A11 trans, A 13 trans). This acid is bound in the triglycerides in the 1,3 position. Via mercury Il-acetate adducts and subsequent chromatography on silica gel a separation of this fatty acid from the seed fatty acids is possible. By this procedure an a-eleostearic acid-free tung-oil mixture is obtained, which consists by one half of C i8:2, 25% of C 18:1 and by 25% of the saturated fatty acids C 16;0, C 18:0 and
