Embodiment 1
[0062] First crush the Echinacea purpurea medicinal material with a moisture content of ≤12.0%, pass it through a 80-mesh sieve, and weigh 1000g; add 8000ml of 70% ethanol solution and mix it with the Echinacea purpurea powder, soak for 30 minutes, extract twice with microwave, and the microwave radiation frequency is 2400-2500 MHz , the extraction temperature is 60°C, each extraction time is 10 minutes, filter and collect the filtrate and residue; the residue is mixed with 20% ethanol solution at a solid-liquid ratio of 1:5, microwave extraction is performed once, and the microwave frequency is 2400- 2500 MHz, the extraction time is 10 minutes, the extraction temperature is 60°C, filter, collect the filtrate, and combine the above filtrates; recover the ethanol from the filtrate under reduced pressure at 40°C, concentrate to a relative density of about 1.04, add an appropriate amount of p-hydroxybenzene Fully dissolve ethyl formate, adjust the pH value of the liquid to 4.0 wit...
Embodiment 2
[0065] First, crush the Echinacea purpurea medicinal material with a moisture content of ≤12.0%, pass through a 80-mesh sieve, weigh 1000g; add 10000ml of 70% ethanol solution and mix it with the Echinacea purpurea powder, soak for 30 minutes, and extract twice with microwaves. The microwave radiation frequency is 2400-2500 MHz , the extraction temperature was 60°C, each extraction time was 15 minutes, filtered and collected the filtrate and residue; the residue was mixed with 20% ethanol solution at a solid-liquid ratio of 1:5, microwave extracted once, and the microwave frequency was 2400- 2500 MHz, the extraction time is 10 minutes, the extraction temperature is 60°C, filter, collect the filtrate, and combine the above filtrates; recover the ethanol from the filtrate under reduced pressure at 40°C, concentrate to a relative density of about 1.03, add an appropriate amount of p-hydroxybenzene Fully dissolve ethyl formate, adjust the pH value of the liquid to 4.5 with a certai...
Embodiment 3
[0068] First, crush the Echinacea purpurea medicinal material with a moisture content of ≤12.0%, pass through a 80-mesh sieve, weigh 2000g; add 20000ml of 70% ethanol solution and mix it with the Echinacea purpurea powder, soak for 30 minutes, extract twice with microwave, and the microwave radiation frequency is 2400-2500 MHz , the extraction temperature is 60°C, each extraction time is 10 minutes, filter and collect the filtrate and residue; the residue is mixed with 30% ethanol solution at a solid-liquid ratio of 1:5, microwave extraction is performed once, and the microwave frequency is 2400- 2500 MHz, the extraction time is 10 minutes, the extraction temperature is 60°C, filter, collect the filtrate, and combine the above filtrates; recover the ethanol from the filtrate under reduced pressure at 40°C, concentrate to a relative density of about 1.10, add an appropriate amount of p-hydroxybenzene Fully dissolve ethyl formate, adjust the pH value of the liquid to 4.0 with a c...
