Embodiment 1

[0043] 50 g of the raw medicinal material of Cornus officinalis is extracted twice with 80% ethanol under reflux, the amount of alcohol added is 20 times of the weight of the medicinal material, and the extraction time is 2 hours. Combine the extracts, filter and concentrate under reduced pressure to 1 / 10 volume, add 95% ethanol to the concentrated solution to make the alcohol content 80%, after alcohol precipitation, refrigerate for 24 hours, filter, and recover ethanol under reduced pressure , to obtain the raw reflux extract of Cornus officinalis.

Embodiment 2

[0045] 50 g of processed medicinal materials of Cornus officinalis is extracted twice with 80% ethanol under reflux, the amount of alcohol added is 20 times of the weight of the medicinal materials, and the extraction time is 2 hours. The extracts were combined, filtered and concentrated under reduced pressure. The concentrated solution was added with 4 times the amount of water to precipitate, then refrigerated for 24 hours, filtered, and the ethanol was recovered under reduced pressure to obtain the reflux extract of the processed product of Cornus officinalis.

Embodiment 3

[0047] 50 g of processed medicinal materials of Cornus officinalis were ultrasonically extracted twice with 80% ethanol for 20 minutes each time, and the amount of alcohol added was 20 times the weight of the medicinal materials. Combine the extracts, filter and concentrate under reduced pressure until there is no alcohol smell, add 95% ethanol to the concentrated solution to make the alcohol content 80%, after alcohol precipitation and precipitation, refrigerate and stand for 24 hours, filter, and recover ethanol under reduced pressure, Obtain the ultrasonic extract of Cornus officinalis processed product.
