 Title    A Micromethod for Rapid Quantitative Determination of Phosphonate Phosphorus  
 Abstract    A rapid method for initial quantitative estim ation o f the phosphate present in com pound containing a carbon-phosphorus bond is described. Two phosphorus assays are employed. One assay is for total phosphorus, which can be determined by digesting with perchloric acid and the other assay is for total non phosphonate phosphorus which can be determined by digesting with sulfuric acid sim ultaneously. The differ­ ence between total phosphorus and the non phosphonate phosphorus determ ined represents the amount o f phosphorus present in a carbon-phosphorus linkage in a crude phospholipids sample.

 Title    Isolation of Beef Brain Phosphonolipids by Thin Layer Chromatography: Their Identification and Silicic Acid Column Chromatographic Separation  
 Abstract    The isolation and identification of the phosphonolipids from beef brain — right lobe, left lobe and cerebellum — is herein reported. The phosphonolipids were isolated by pre­ parative thin layer chromatography (TLC) using the sol­ vent system methanol/water (2:1, v/v) and identified pre­ liminarily by TLC. The isolated phosphonolipids were sub­ jected to silicic acid column chromatographic separation and the thus separated phosphonolipids were identified by TLC, nitrogen-phosphorus determinations and IR spec­ troscopy.

 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.
