| titleOfInvention | Preparation method of corosolic acid |
| abstract | The invention relates to a preparation method of corosolic acid. A plant raw material containing corosolic acid is routinely extracted and processed, a binary resin bed separation technology is applied, and the obtained extract is specially acidified when the extract has a certain purity. Impurities in the primary extract are acetylized to change the physical and chemical characteristics, and corosolic acid is separated and purified through solvent dissolution, filtration and crystallization. Pure corosolic acid crystals with the purity of above 95.00% which can be directly used for preparing drugs are finally obtained in the invention. |
