Embodiment 1-4 and comparative example 1-3

[0094] Embodiment 1-4 and comparative example 1-3 prepare plant extract by following process:

[0095] 1. Dry and pulverize the above-mentioned plants in proportion and dosage respectively, and mix them through an 80-mesh sieve.

[0096] 2. Add 1800mL of 70% ethanol. Ultrasonic treatment with a frequency of 20 kHz was used for 50 minutes, and the temperature of ethanol in the ultrasonic treatment was 50° C.

[0097] 3. Use a filter material with a filtration precision of 100 mesh for preliminary filtration, and then use a filter cloth of 1000 mesh for a second filtration to obtain filtrate A and seal it for later use.

[0098] 4. Add 900 mL of ethyl acetate to the filter residue. Ultrasonic treatment with a frequency of 20 kHz was used for 35 minutes, and the temperature of ethyl acetate during the ultrasonic treatment was 45° C.
