Embodiment 1
[0102] Embodiment 1 golden buckwheat extraction process
[0103] Pulverize the golden buckwheat crude drug and pass through a 50-mesh sieve to obtain golden buckwheat coarse powder; add 2kg of golden buckwheat coarse powder into 50% ethanol solution of 10 times the amount (weight ratio, the same below), heat and reflux twice at 60°C , 1.5 hours each time, combine the filtrates, filter, and concentrate the filtrate under reduced pressure at 60°C to no alcohol smell, add an appropriate amount of 2.1kg of water to dissolve, filter with suction, and set aside. Take the pretreated D-101 macroporous resin and pack it into a column. The flow rate of the drug solution is 2 resin column volumes / hour, and the adsorption is for 4 hours. First, 6 column volumes of water are used to elute and remove impurities. The flow rate of impurity removal is 4 resin columns. volume / hour, then eluted 8 column volumes with 70% ethanol, and the elution flow rate was 2 resin column volumes / hour, reclaime...
Embodiment 2
[0104] Example 2 Extraction process of Evodia rutaecarpa
[0105]Pulverize the crude drug of Evodia rutaecarpa, pass through a 50-mesh sieve to obtain coarse powder of Evodia rutaecarpa; add 10 times the amount of hydrochloric acid ethanol (alcohol concentration is 80%) solution with a pH value of 3 to 6kg of Evodia rutaecarpa coarse powder, heat and reflux 3 times, each time 1.5 h, filter, combine the filtrates, concentrate to 50°C and measure the relative density to be 1.20, let cool to obtain a concentrated solution, adjust the pH value of the concentrated solution to 2, let stand, and centrifuge to obtain 4000 ml of a supernatant, which is set aside. Take 4000ml of 732 strong-acid cation exchange resin, pack it into a column, the diameter-to-height ratio is about 1:10, and the column adsorption flow rate of the liquid medicine is 1 resin column volume / hour. Until the effluent is colorless, the elution flow rate is 2 resin column volumes / hour; the 80% ethanol eluate is coll...
