5 results about "GLYCERYL TRIOLEATE" patented technology

The application discloses a refining method of glyceryl oleate series products. The glyceryl oleate mixture is used as raw material, the mixture is melted by heating, then the melted liquid is flowed through a panel containing different temperature zones, and crystals are separated in the corresponding temperature zones by using the difference of solidification points of different components, so that glyceryl monooleate, glycerol, glyceryl dioleate and glyceryl trioleate are obtained respectively. The separation of each component in the glyceryl oleate mixture is realized. The method does not introduce solvent and adsorbent, is green and environment-friendly, and the obtained products can meet the demand of high-purity glyceryl monooleate and glyceryl dioleate for biological products.

The invention provides a high-stability blueberry anthocyanin polycystic liposome and a preparation method of the high-stability blueberry anthocyanin polycystic liposome. The preparation raw materials comprise 5 to 12 parts of a pH response type phospholipid derivative, 3 to 8 parts of mesoporous silica-polydopamine hybrid nanoparticles, 28 to 42 parts of egg yolk lecithin, 8 to 12 parts of cholesterol, 5 to 9 parts of glyceryl trioleate, 2 to 5 parts of vitamin E succinate, 10 to 18 parts of a citric acid-malic acid buffer solution, 45 to 85 parts of trehalose, 16 to 32 parts of a Tween 80-Arabic gum compound, 4 to 8 parts of chitosan quaternary ammonium salt and 5 to 13 parts of polyethylene glycol-2000. 160-280 parts of ultrapure water and 6-22 parts of blueberry anthocyanin. The blueberry anthocyanin polycystic liposome disclosed by the invention has high encapsulation efficiency, excellent photo-thermal stability and long-term storage stability.

The application discloses a triglyceride and cholesterol mixed quality control liquid and a preparation method and application thereof, relates to the technical field of in vitro diagnostic reagents, and solves the problem of poor compatibility of components of the triglyceride and cholesterol mixed quality control liquid. The triglyceride and cholesterol mixed quality control liquid comprises a mother liquor and a diluent, the mother liquor comprises the following components in percentage by mass: glyceryl trioleate 7-10%, Triton X-100 85-90% and cholesterol 3-5%; and the diluent comprises the following components in percentage by mass: isopropyl alcohol 50-51%, sodium phosphate buffer 39-40%, sodium cholate 9.50-9.75% and sodium benzoate 0.25-0.50%. The mixed quality control liquid is high in stability and accuracy, can detect triglyceride and cholesterol at the same time, and the detection results do not interfere with each other.
