| titleOfInvention | Method for extracting and separating wedelolactone from herba ecliptae |
| abstract | The invention relates to a method for extracting and separating wedelolactone from herba ecliptae. The method comprises the following steps: primary extraction, secondary extraction, tandem column separation and crystallization and is characterized by grinding a raw material herba ecliptae, carrying out extraction, carrying out tandem column separation and then carrying out crystallization, thus obtaining required wedelolactone. The method for extracting wedelolactone from the raw material herba ecliptae is simple to operate, has the advantages of high product content and high recovery rate and is suitable for industrial production. |
