Embodiment 1
[0147](1) Take 600g of rhubarb and 1500g of salvia miltiorrhiza, crush them into coarse particles, add 8 times the amount of water to soak for 20 minutes, heat and ultrasonically extract for 20 minutes for the first time, filter; heat and ultrasonically extract for 10 minutes for the second time, filter, and combine two water extractions Liquid, concentrated under reduced pressure to a relative density of 1.21 at 60°C, added 5% gelatin solution to remove tannin, filtered, added ethanol to make the alcohol content 75%, stood still, filtered, took the filtrate and concentrated under reduced pressure to a relative density of 60 At 1.21 °C, recover ethanol, continue to add ethanol to make the alcohol content 80%, let stand, filter, recover ethanol, add water for injection to 2-3 times the amount of the liquid medicine, then add 0.3%-0.5% activated carbon, boil After 30 minutes, filter and adjust the pH value to 7.4-7.7 to obtain rhubarb and salvia miltiorrhiza extracts for later us...
Embodiment 2
[0151] (1) Take 600g of rhubarb and 1500g of salvia miltiorrhiza, crush them into coarse particles, add 8 times the amount of water to decoct, combine the extracts, filter, collect the filtrate, concentrate, enter the macroporous resin column for adsorption and separation, and collect the first effluent; first wash with water Remove, collect the eluate, and then elute with 50%-60% ethanol, collect the ethanol eluate, recover the ethanol until it has no alcohol smell, combine the effluent, concentrate under reduced pressure to a relative density of 1.21 at 60°C, add 5% Remove tannins from the gelatin solution, filter, add ethanol to make the alcohol content 75%, let stand, filter, take the filtrate and concentrate under reduced pressure to a relative density of 1.21 at 60°C, recover ethanol, continue to add ethanol to make the alcohol content 80% , stand still, filter, recover ethanol, add water for injection to 2-3 times the amount of the liquid medicine, then add 0.3%-0.5% act...
Embodiment 3
[0155] (1) Take 600g of rhubarb and 1500g of salvia miltiorrhiza, crush them into fine particles and put them in the extraction kettle for CO 2 For supercritical extraction, the flow rate of the supercritical fluid entering the extraction kettle is 35L / h, the extraction pressure is 30MPa, the extraction temperature is 45°C, and the extraction time is 2.5h. The rhubarb and Danshen high-pressure fluids flowing out of the extraction kettle enter the separation kettle for Separation, separation pressure I is 8 Mpa, separation temperature I is 30°C; separation pressure II is 6 Mpa, separation temperature II is 25°C, collect the extracts of rhubarb and salvia miltiorrhiza, add water for injection to 2-3 times the amount of the liquid medicine , then add 0.3%-0.5% activated carbon, boil for 30min, filter, adjust the pH value to 7.4-7.7, and obtain rhubarb and salvia miltiorrhiza extracts, set aside;
[0156] (2) Take 2100g of Astragalus membranaceus and crush it into fine particles, ...
