Embodiment 1
[0034] A method for preparing a biological agent capable of preventing and treating influenza, the method comprising the following steps: weighing 20% of raw materials Echinacea flower, 20% of Houttuynia cordata, 25% of yellow flower, 15% of wild chrysanthemum flower, Rhodiola rosea 20%, add purified water 6 times the weight of raw materials, reflux extraction at 60°C for 3h, and repeat twice. Put the extract into a high-speed centrifuge at 8000rpm for clarification. The clarified liquid was put into a 5K molecular weight ultrafiltration membrane for interception to obtain a residual liquid A. Put the permeate into macroporous adsorption resin HPD-100 chromatographic column at a flow rate of 50ml / min. Elute with 30% ethanol solution to obtain eluent B.
[0035] The residual solution A and the eluent B were mixed at 60°C and vacuum concentrated to a density of 1.03 to obtain a concentrated solution. The concentrated solution was placed in a vacuum drying oven at 65°C and a ...
Embodiment 2
[0037]A method for preparing a biological agent capable of preventing and treating influenza, the method comprising the following steps: weighing 30% of raw materials Echinacea flower, 30% of Houttuynia cordata, 20% of yellow flower, 10% of wild chrysanthemum flower, and Rhodiola rosea 10%, add pure water 10 times the weight of raw materials, reflux extraction at 80°C for 2 hours, and repeat twice. Put the extract into a high-speed centrifuge at 10,000 rpm for clarification. The clarified liquid was put into a 10K molecular weight ultrafiltration membrane for interception to obtain a residual liquid A. Put the permeate into macroporous adsorption resin HPD-100 chromatographic column at a flow rate of 100ml / min. Elute with 80% ethanol solution to obtain eluent B.
[0038] The residual solution A and the eluent B were mixed at 80°C and vacuum concentrated to a density of 1.06 to obtain a concentrated solution. The concentrated solution was placed in a vacuum drying oven at 85°...
Embodiment 3
[0040] A method for preparing a biological agent capable of preventing and treating influenza, the method comprising the following steps: weighing 25% of echinacea, 25% of Houttuynia cordata, 15% of yellow flower, 20% of wild chrysanthemum, and Rhodiola rosea 15%, add pure water 6-10 times the weight of raw materials, reflux extraction at 60-80°C for 2-3h, repeat twice. Put the extract into a high-speed centrifuge at 9000rpm for clarification. The clarified liquid was put into a 6K molecular weight ultrafiltration membrane for interception to obtain a residual liquid A. Put the permeate into macroporous adsorption resin HPD-100 chromatographic column at a flow rate of 60ml / min. Elute with 50% ethanol solution to obtain eluent B.
[0041] The residual solution A and the eluent B were mixed at 70°C and vacuum concentrated to a density of 1.04 to obtain a concentrated solution. The concentrated solution was placed in a vacuum drying oven at 70°C and a vacuum degree of 600 Pa to...
