| titleOfInvention | Preparation process for extracting high-purity ursolic acid from rosemary |
| abstract | The invention provides a preparation process for extracting high-purity ursolic acid from rosemary, which is characterized in that an ursolic acid product with the purity of more than 99 percent is obtained by adopting different solvents for leaching, filtering, separating, crystallizing and purifying, and meanwhile, ursolic acid products with the contents of 5-20 percent, 40-60 percent and 50-70 percent and carnosic acid products with the content of 20-40 percent can also be obtained. The preparation process for extracting the high-purity ursolic acid disclosed by the invention has the advantages of high utilization rate of raw materials, repeated and recycled use of the solvent, small environmental pollution and easiness in realization of industrial production. |
