Method for purifying carabrone |
| abstract |
The invention discloses a method for purifying carabrone. The method comprises the following steps: (1) soaking or ultrasonically extracting carpesium abrotanoides in a water solution of inorganic strong base at 0-100 DEG C; then, filtering, adjusting the pH value of filter liquor to be 1-7 by the inorganic strong base to generate deposits; (2) removing the deposits generated in the step (1), and then extracting supernatant liquid by an organic solvent to obtain extracting liquid; and (3) performing silica column chromatography on the extracting liquid obtained from the step (2) to obtain the carabrone. The method is easy to operate; the obtained carabrone is relatively high in purity. |
