Abstract

The invention provides a method for preparing high-purity marine polyunsaturated fatty acid phospholipid by virtue of codfish viscera. Processes of efficient solvent extraction, rapid purification, ultrasonic-enhanced supercritical extraction, polystyrene gel column chromatography and the like are adopted, so that the method has the advantages of environment friendliness, energy saving and high efficiency. The high-purity marine polyunsaturated fatty acid phospholipid is extracted by virtue of codfish processing wastes. An extraction process is convenient to operate, and extraction efficiency is high; the purity of the phospholipid is more than or equal to 97 percent. According to the method, on one hand, the problem of waste of a large number of residual marine byproduct resources is solved, and environmental pollution is reduced; on the other hand, preparation sources for the phospholipid are enriched, the raw materials are intensive and low-cost, the extraction cost of the phospholipid is reduced, and great ecological, economic and social significance is achieved.

Description

technical field

[0001] The invention belongs to the technical field of preparation of marine active substances, and in particular relates to a method for extracting high-purity marine polyunsaturated fatty acid phospholipids from cod viscera. Background technique

[0002] Phospholipids are a class of phosphate-containing lipid compounds, which are the basic components of tissue cells, including sphingomyelin and glycerophospholipids. The former is mainly found in the erythrocyte membrane of higher animals, while the latter is abundant in animal liver, brain and ovary. Phospholipids not only have high nutritional value, but also have physiological regulation functions, promote human metabolism, enhance immunity, and prevent diseases. Now, the United States, Europe, Japan and other developed countries have applied phospholipids in clinical practice to prevent brain, heart, liver, tumor and other diseases. In addition, phospholipids also have the characteristics of emulsifica...
