Embodiment 1
[0017] Take 270g of Radix Scrophulariae, 216g of Rehmannia glutinosa, and 216g of Radix Ophiopogon japonicus, add 10 times the weight of medicinal materials in water, soak for 0.5h, decoct for 1 hour, filter, add 8 times the weight of medicinal materials in water, decoct for 1 hour, and filter the medicinal liquid The two decoction liquids were combined, concentrated under reduced pressure to a relative density of 1.05 at 60°C, added ethanol so that the volume percentage of the alcohol content reached 75%, stirred, left to stand, filtered, and the filtrate was concentrated under reduced pressure to a relative density of 65°C 1.25, and recover ethanol to obtain concentrated solution, use silica gel to refine, pre-load the selected silica gel into the resin column, and at the same time, after diluting the concentrated solution with purified water, pass it through a reversed-phase silica gel column to remove impurities in the liquid , collect all the effluent, continue to concentr...
