Extraction Process

The preparation method of the extract of Hypericum perforatum includes the following steps: firstly, dry forsythia and crushed into powder of Hypericum perforatum, and then weigh the enzyme to dissolve the enzyme in the warm water, activate the enzyme solution into the water bath, mix the powder of Hypericum perforatum with water, , Cooling, adjusting pH with hydrochloric acid, shaking, water bath heating, adding the activation of the enzyme solution, mixing, enzymolysis, filtration, discard the filtrate, the enzyme powder, add ethanol reflux extraction, filtration, combined filtrate , Concentrating under reduced pressure, recovering ethanol and drying to obtain hypericum perforatum extract. The invention improves the hypericin content in the extract, and the filtrate discarded after enzymolysis takes away a large amount of water-soluble impurities, so that the extract does not Re-hygroscopic, the use of biological methods safe and pollution-free, simple operation, easy to industrial applications
