[Solubility of phospholipids in oilseeds depending on the extraction conditions (author's transl)]

The results of the determination of oil content depend on the method and on the solvent used. Extractions by the Twisselmann method give increasing yields in the order n-pentane, hexane, and n-heptane. Using the Soxhlet extraction, much lower yields were obtained with n-heptane than with the other two solvents. In both methods, the phospholipid content in the extracts depends only on the solvent and not on the method used. The yield and composition of the mixture of phospholipids vary in the different methods of extraction.
