Embodiment 1
[0039] Example 1: Preparation process of Fangfeng Total Chromone
[0040] Take 1kg of Fangfeng decoction pieces, extract 3 times with 10L of 70% ethanol under reflux, extract for 1 hour each time, and recover the solvent under reduced pressure to obtain the extract, add water to disperse and dissolve, so that the concentration of the aqueous solution is 3.84mg / mL (based on the total chromone content) , centrifuged at 3000 rpm for 30 min, took the supernatant, passed it through 5L AB-8 macroporous adsorption resin, the adsorption flow rate was 1.0mL / min, the ratio of diameter to height of the resin column was 1:8, and the loading volume was 7.68 mg / min. mL (based on total chromone content), 10% ethanol elutes 2 times the resin volume for impurity removal, the impurity removal flow rate is 1.0mL / min, 70% ethanol elutes 5 times the resin volume, and the elution flow rate is 2.0mL / min min, collect the 70% ethanol eluate, recover the solvent, and dry under reduced pressure, which i...
Embodiment 2
[0041] Example 2: Preparation process of Fangfeng total chromone
[0042] Fangfeng decoction pieces 1kg, 50% ethanol 15L, reflux extraction 3 times, 1.5 hours each time, recover the solvent, add water to disperse and dissolve the extract, make the concentration of the aqueous solution 3.00mg / mL (based on the amount of total chromone), at 3000 rpm Centrifuge for 30min at a speed of 1 / min, take the supernatant, and pass through 6L AB-8 macroporous adsorption resin, the adsorption flow rate is 1.0mL / min, the diameter-height ratio of the resin column is 1:7, and the sample loading is 7.00mg / mL (based on the total Chromone meter), 10% ethanol elutes 2 times of resin volume to remove impurities, and the flow rate of impurity removal is 1.0mL / min, 50% ethanol elutes 4 times of resin volume, the elution flow rate is 2.0mL / min, collects 50 % ethanol eluent, recover the solvent, and dry under reduced pressure, which is the total chromogenone extract of Radix Radix Radix. The total chro...
Embodiment 3
[0043] Example 3: Preparation process of Fangfeng total chromone
[0044] Fangfeng decoction pieces 1kg, 70% ethanol 12L reflux extraction 2 times, each extraction 2 hours, recover the solvent, add water to disperse and dissolve the extract, so that the concentration of the aqueous solution is 4.00mg / mL (based on the amount of total chromone), at 3000 rpm Centrifuge at a speed of 1 minute for 30 minutes, take the supernatant, and pass through 7L AB-8 macroporous adsorption resin, the adsorption flow rate is 1.0mL / min, the diameter-height ratio of the resin column is 1:9, and the sample loading is 8.00mg / mL (based on total color Protoketone meter), water eluted 4 times the resin volume for impurity removal, the impurity removal flow rate was 1.0mL / min, 90% ethanol eluted 4 times the resin volume, the elution flow rate was 2.0mL / min, collected 90% ethanol wash The liquid is removed, the solvent is recovered, and dried under reduced pressure, which is the total chromone extract o...
