[0035] In the present invention, the preparation method of Pulsatilla pulsatillae extract comprises the following steps:
[0036] (1) After taking 10g of Pulsatilla pulsatillae and pulverizing it, add 150ml of 65wt% ethanol aqueous solution, heat and reflux for 3 hours, filter, and recover the filter residue for subsequent use;
[0037] (2) After the filtrate obtained in step (1) is concentrated, it is diluted with distilled water, after being adsorbed by AB-8 resin, it is eluted with 60wt% ethanol for 45 minutes, and the eluent is concentrated and dried to obtain A powder;
[0038] (3) Take the filter residue in step (1), dry it, add 90wt% ethanol and 0.8 to 2 times the volume of the powder material after drying, extract with microwave for 1 hour, centrifuge and precipitate, and filter out the supernatant. Concentrate and dry to obtain B powder, and blend the A powder and B powder obtained in the step (2) in a weight ratio of (3-5): 1 to obtain the Pulsatilla pulsatillae extr...
