| titleOfInvention | Preparation method of Stellarine A |
| abstract | The invention discloses a simple little-pollution preparation method of Stellarine A. The method is as below: 1) crushing roots of Radix Stellariae into 20-80 mesh, extracting the radix glehniae in a CO2 supercritical extraction tank, introducing liquid CO2 with flow of 1-5 ml/min/ g raw material, and simultaneously introducing chloroform as an entrainer with flow of 1-3 ml/min/ g; and extracting at 30-60 DEG C at a pressure of 15-30 MPa for 1-3 h and parsing to obtain an extract; 2) dissolving the extract with methanol solution, passing the solution through an alumina short column, collecting and concentrating liquid, separating the concentrated solution with high speed counter current chromatogram, carrying out on-line monitoring by an ultraviolet detector, collecting flow components, and drying under reduced pressure to obtain Stellarine A. The method is suitable for preparation of Stellarine A with high purity. |
