A kind of preparation method of dipalmitoyl phosphatidic acid |
| abstract |
The invention provides a method for artificially synthesizing phospholipid dipalmitoyl phosphatidic acid (DPPA). The method uses 1,2-dipalmitoyl-sn-glycerol as a raw material, undergoes an esterification reaction, and then undergoes a hydrolysis reaction to obtain a product. High-purity dipalmitoyl phosphatidic acid is obtained by dissolving, filtering and recrystallization. The dipalmitoyl phosphatidic acid (DPPA) prepared by the method of the present invention can be used as a pharmaceutical excipient for various types of medicines such as liposomes, emulsifiers and capsules. |
