Abstract:

Due to the difference in solubility of concentrated soybean phospholipids in different solvents, a solvent method to prepare phosphatidylcholine with high purity was established. Concentrated soybean phospholipids were subjected to oilremoval by acetone, isolation by ethanol, decoloration by active carbon, and extraction by acetonitrile. The purity of prepared phosphatidylcholine was up to 95%. Fatty acid compositions of soybean phosphatidylcholine were mainly composed of polyunsaturated fatty acids, and the contents of linoleic acid and linolenic acid were 70.71% and 11.04%, respectively.

Key words: solvent method, phosphatidylcholine, fatty acid
