Embodiment 1

[0037] The preparation of embodiment 1 rhizome extract

[0038] a. Take 1Kg Guanzhong, crush it, soak it with 6 times the volume of 75% ethanol for 8 hours, pour the Guanzhong and ethanol extract into a three-necked flask and put it on the electric heating mantle for electronic temperature regulation, and keep boiling for 1 hour after boiling hour, the extract was poured out and suction filtered to obtain the supernatant for subsequent use;

[0039] b. Add 4 times the volume of 75% ethanol to the liquor poured out of the extract, boil, keep boiling for 1 hour, pour out the extract and suction filter to obtain the supernatant for later use;

[0040] c. Repeat step b2 times;

[0041] d. Combine the supernatants and concentrate under reduced pressure to obtain 202 grams of extract for subsequent use, with a yield of 20.2%.

Embodiment 2

[0042] The preparation of embodiment 2 ebony extract

[0043] a. Take 1Kg ebony plum, soak it with 6 times the volume of 75% ethanol for 8 hours, pour the ebony plum and the ethanol extract into a three-necked flask and put it on an electronic thermostat electric heating mantle, keep boiling for 1 hour after boiling, and pour the ebony extract into a three-necked flask. The extract was poured out and suction filtered to obtain the supernatant for subsequent use;
