The invention provides a preparation method of an illicium verum extract, the illicium verum extract and application of the illicium verum extract, and relates to the technical field of illicium verum extraction. The preparation method comprises the following steps: extracting illicium verum and illicium verum powder through heat reflux of 92%-98% ethanol to obtain illicium verum total alcohol extract, extracting with petroleum ether to obtain water layer extract, concentrating, extracting with water to remove impurities, and performing column chromatography separation with 45%-55% ethanol. The method has the advantages of short extraction steps, simple production process, no generation of toxic and harmful substances, low production requirements and low cost, and is beneficial to large-scale industrial production. The illicium verum extract prepared by the preparation method disclosed by the invention is clear in component, rich in various natural anti-inflammatory and antioxidant components, capable of inhibiting the activity of alpha-glucosidase, capable of remarkably reducing the blood sugar level after being loaded by cane sugar or starch and playing a role in reducing postprandial blood sugar, and has no obvious toxicity in an in-vivo experiment; good safety is shown.

The application discloses a preparation method of a preparation for treating hyperuricemia and gout and application of the preparation. A star anise is used as raw material to be crushed, and medicinal powder is refluxed and extracted to obtain star anise extract A and star anise extract B after the organic phase and the aqueous phase are separated by standing. A chrysanthemum is used as raw material to be crushed, and medicinal powder is put into water containing a composite enzyme, and chrysanthemum extract A is obtained after extraction liquid is concentrated under reduced pressure and dried. The chrysanthemum extract A is put into a solution containing a hydrolytic enzyme to be enzymolyzed, and chrysanthemum extract B is obtained after the enzymolyzed liquid is concentrated under pressure and dried. The star anise extract A, the star anise extract B and the chrysanthemum extract B are added into a pharmaceutically acceptable carrier to prepare chrysanthemum and star anise preparation for reducing uric acid, such as granules, tablets, capsules, oral liquid and the like. The chrysanthemum and the star anise have a remarkable effect of reducing uric acid under the specific composition, and are further developed into related dosage forms, so that the application of the traditional Chinese medicine compound taking the star anise and the chrysanthemum as cores in the field of treating hyperuricemia and gout is greatly promoted.

The application provides a preparation method of star anise extract, the extract and application thereof, and relates to the technical field of star anise extraction. The preparation method comprises the following steps: 92%-98% ethanol is used to heat reflux extraction of star anise powder to obtain star anise total alcohol extract, petroleum ether is used to obtain water layer extract, after concentration, water is used to extract and remove impurities, and then 45%-55% ethanol is used for column chromatography separation.
