Process for extracting deoxyschizandrin from schisandra chinensis |
| abstract |
The invention relates to a process for extracting deoxyschizandrin from schisandra chinensis, which is characterized in that a lignan total extract is prepared by a method of ultrasonic-assisted petroleum ether extraction and alkali alcohol back extraction, and then the lignan total extract is subjected to silica gel alumina mixed column chromatography twice, elution, solvent recovery, petroleum ether-acetone or cyclohexane-ethanol recrystallization and drying to obtain the deoxyschizandrin. The invention has high specificity. |
