Embodiment 1
[0146] Example 1 Preparation of Polygonum cephalum extract
[0147] Take 500kg of Polygonum cephalum medicinal material, chop it up, add water to decoct twice, each time for 2 hours, filter, concentrate the filtrate under reduced pressure to a relative density of 1.10-1.15, let it cool, add ethanol to make the alcohol content to 60%, and refrigerate for 24 hours, filter, and recover the ethanol from the filtrate until there is no alcohol smell, add it to the treated polyamide column (30-60 mesh, ethanol wet packing, pre-wash with appropriate amount of ethanol, then wash with water until there is no alcohol smell, set aside) , wash with 2 times the column volume of water, then wash with 2 times the column volume of 10% ethanol, discard the washing solution, and then elute with 3 times the column volume of 70% ethanol, collect the eluate, recover the ethanol and concentrate Form into a concentrated solution with a relative density of 1.08 to 1.12, and spray dry to obtain.

Embodiment 2
[0167] Example 2 Preparation of Poria cocos extract
[0168] Weigh 500 kg of Poria cocos, crush it into fine powder, add 0.5mol / L sodium hydroxide solution to extract twice, stir, add 8 times the amount of solvent for the first 4 hours, and add 6 times the amount of solvent for the second 3 hours , stirred at low temperature, suction filtered, combined filtrates, neutralized with 10% acetic acid, refrigerated for 12 hours, and filtered. The precipitate was washed successively with water, acetone and ether, and dried to obtain the obtained product.
[0169] A total of 41.2 kg of Poria cocos extract was obtained, with a yield of 8.24%.
