| Abstract: | Summary Investigations of the phospholipids of sunflower seeds have been performed which have confirmed the known structures of the phosphatidylcholines and phosphatidylethanolamines. It has been established that the inositophosphatides have the structure of monophosphoinositides. The fatty acid compositions of the individual groups of phospholipids have been studied: they consist mainly of the same selection of acids as the phospholipid complex with the glycerides of the sunflower. The phospholipids form a sequence with respect to increasing saturation: phosphatidylcholines, phosphatidylethanolamines, bis-phosphatidic acids, monophosphoinositides.A solvent system for the identification of the water-soluble products of the acid hydrolysis of phospholipids by chromatography in a thin layer of silica gel has been proposed.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Uzbek SSR.
