Description
Technical field
The present invention relates to a kind of method that is rich in timnodonic acid and docosahexenoic acid phosphatide of from the marine animal raw material, extracting.
Background technology
Phosphatide is the important composition composition of cytolemma, as widespread uses in medicine, makeup, foodstuffs industry such as liposome, emulsifying agents.The character of the physiologically active of phosphatide and the composition of its lipid acid and polarity end is closely related, and some phosphatide with ad hoc structure have very high pharmaceutical use.Phosphatide is one of cytolemma main component, still be the form of stocking of numerous informational molecule precursors simultaneously on cytolemma, important effect is arranged in the regulation and control of physical function, has the multiple nutrients nourishing function: regulate body metabolism, enhancing physical efficiency, brain tonic, benefit brain, eliminate brain fag, improve human body memory; Can reduce blood of human body cholesterol, regulating blood fat, prevent atherosclerosis; Can protect the human liver, prevent and treat fatty liver; Can prevent and treat gallbladdergallstonecholetithiasis, senile osteoporosis, Keshan disease; Also have the fitness to human body, the function of being healthy and strong.
The production of phosphatide mainly is to extract from soybean and yolk both at home and abroad at present, limit by raw material natural acid compositing characteristic, can not obtain to be rich in the phosphatide of timnodonic acid (EPA) and docosahexenoic acid (DHA).About using supercritical carbon dioxide extraction to remove neutral fat and cholesterol in the marine animal raw material powder, utilize aqueous ethanolic solution to extract the document that is rich in EPA and DHA phosphatide again, Shang Weijian has report.
Summary of the invention
The purpose of this invention is to provide a kind of ovum with marine animal, sexual gland etc. is raw material, and efficient, environmental protection, safety, the extracting method capable of being industrialized of EPA and DHA phosphatide is rich in acquisition in large quantities, to remedy the above-mentioned deficiency of prior art.
The method of EPA and DHA phosphatide is rich in a kind of extraction, it is characterized in that earlier the marine animal raw material being made homogenate with colloidal mill, with the lyophilize of gained homogenate, after with pulverizer the gained solid substance being pulverized again, utilize supercritical co to slough neutral fat and cholesterol in this raw material powder, extract with aqueous ethanolic solution then.
The product yield height that the present invention extracts, purity is higher, the leaching process environmentally safe, to producers' toxicological harmless, have promote that infant's brain grows, physiologically actives such as hypermnesis, promotion infant optic nerve and retinal development, prevention and treatment cardiovascular disorder, anti-inflammatory, anticancer, strengthening immunity.Studies show that, the phosphatide ratio that is combined with EPA and DHA does not have better cytolemma penetrance in conjunction with the phosphatide of EPA and DHA, stronger anti-tumor activity and more effective immunoloregulation function, thereby have higher value of exploiting and utilizing as healthcare products or medical material.
