| titleOfInvention | Method for preparing high-purity phosphatidylcholine |
| abstract | The invention relates to a method for preparing high-purity phosphatidylcholine, and is characterized in that the method comprises the following steps of: an alcohol treatment step, wherein crude phospholipids are used as raw materials, low carbon alcohol and water are used as mixed solvents, an alcohol soluble product is separated by extraction separation; a silicagel column chromatography step, wherein the product obtained in the previous step is subject to silicagel column chromatography, ethanol is used for gradient elution, and the product solution is collected; a drying step, wherein the product solution is subject to vacuum concentration and freeze drying to obtain the high-purity phosphatidylcholine. The method of the invention adopts a single elution solvent, which allows the production process to be nontoxic, free of pollution, and free of three wastes. The separated fillers can be recycled, which saves labor and time, and cause no harmful solvent introduction; the raw materials are not limited within certain sources, and can be derived from phospholipids of various plants and animals. |
