Embodiment 1

[0020] refer to figure 1 , the preparation method steps of Hypericum perforatum extract in the present embodiment are: (1) medicinal material pretreatment: remove weeds from the above-ground part of Hypericum perforatum in full flowering stage, cut into the length of 1cm; (2) Extract: use 90% by weight % of ethanol, reflux extraction for 3 times, the first reflux extraction for 1 hour, wherein the amount of medicinal materials was 5 times that of the solution, and the second to third reflux extraction for 1.5 hours, wherein the amount of medicinal materials was 7 times that of the solution, combined The above extract is filtered, and the ethanol is recovered under reduced pressure until the alcohol content is 30%. The mass ratio of the medicinal material and the solution in the filtrate is 1:7, and it is left to stand. After clarification, filter to obtain the filtrate; (3) put it on the column Elution: Pass the obtained filtrate through the treated macroporous resin, and when...

Embodiment 2

[0023] refer to figure 1 , the preparation method steps of Hypericum perforatum extract in the present embodiment are: (1) medicinal material pretreatment: remove weeds from the above-ground part of Hypericum perforatum in full flowering stage, cut into the length of 1.5cm; (2) extract: use mass percentage as 60% ethanol, reflux extraction for 5 times, the first reflux extraction for 2 hours, wherein the amount of medicinal materials is 7 times that of the solution, the second to fifth reflux extraction for 1 hour, wherein the amount of medicinal materials is 4 times that of the solution, Combine the above extracts, filter, and reclaim ethanol under reduced pressure until the alcohol content is 55%, the mass ratio of the medicinal materials and the solution in the filtrate is 1:8, let stand, and after clarification, filter to obtain the filtrate; (3) Column elution: pass the obtained filtrate through the treated macroporous resin, and when the liquid level of the filtrate is 3...

Embodiment 3

[0026] refer to figure 1 , the preparation method step of the Hypericum perforatum extract in the present embodiment is: (1) medicinal material pretreatment: remove the weeds from the above-ground part of Hypericum perforatum in full flowering stage, cut into the length of 2cm; (2) extract: use 70% by weight % of ethanol, reflux extraction 2 times, the first reflux extraction for 3 hours, wherein the amount of medicinal materials is 5 times the amount of the solution, the second reflux extraction for 2 hours, wherein the amount of medicinal materials is 8 times the amount of the solution, combined the above extraction Liquid, filtered, ethanol is recovered under reduced pressure until the alcohol content is 80%, the mass ratio of medicinal materials and solution in the filtrate is 1:7, let stand, after clarification, filter to obtain the filtrate; (3) column elution : the resulting filtrate flows through the treated macroporous resin, and when the liquid level of the filtrate ...
