Embodiment 1
[0025] Take 194g of angelica, 42g of Sanqi, 83g of safflower, 167g of peony bark, 83g of peach kernel, 167g of windproof, 167g of herb, 42g of Angelica dahurica, 417g of purslane, 83g of red peony, and 194g of astragalus. Added to the CO2 supercritical extractor, ethanol is used as entrainer, the entrainer accounts for 4% by volume of the total extraction solvent, extraction pressure is 15MPa, temperature is 30°C, CO 2 The flow rate is 1ml / g crude drug·min, the extraction time is 150min, and the supercritical extract is obtained for later use; the rest of the traditional Chinese medicine is taken, pulverized, added with 2L of 70% ethanol, and put into a microwave extraction device for microwave extraction, the extraction power is 400W, and the extraction is performed twice, Combine the extracts for 4 minutes each time, concentrate, add to D101 macroporous adsorption resin column, elute with 50% ethanol, collect 5 times the column volume eluate, recover ethanol under reduced pre...
Embodiment 2
[0028] Take 194g of angelica, 42g of Sanqi, 83g of safflower, 167g of peony bark, 83g of peach kernel, 167g of windproof, 167g of herb, 42g of Angelica dahurica, 417g of purslane, 83g of red peony, and 194g of astragalus. Join to CO 2 In a supercritical extractor, ethanol is used as an entrainer, and the volume percentage of the entrainer in the total extraction solvent is 6%, the extraction pressure is 30MPa, the temperature is 50°C, and the CO 2 The flow rate is 3ml / g crude drug·min, the extraction time is 180min, and the supercritical extract is obtained for use; the rest of the traditional Chinese medicine is taken, crushed, added 2L of 70% ethanol, and put into a microwave extraction device for microwave extraction. The extraction power is 600W, and the extraction is performed twice. 8 minutes each time, combine the extracts, concentrate, add to D101 macroporous adsorption resin column, elute with 50% ethanol, collect 5 times the column volume eluate, recover ethanol unde...
Embodiment 3
[0031] Take 194g of angelica, 42g of Sanqi, 83g of safflower, 167g of peony bark, 83g of peach kernel, 167g of windproof, 167g of herb, 42g of Angelica dahurica, 417g of purslane, 83g of red peony, and 194g of astragalus. Join to CO 2 In the supercritical extractor, ethanol is used as an entrainer, and the entrainer accounts for 5% by volume of the total extraction solvent, the extraction pressure is 20MPa, the temperature is 40°C, and the CO 2 The flow rate is 2m1 / g crude drug·min, the extraction time is 160min, and the supercritical extract is obtained for use; the rest of the traditional Chinese medicine is taken, crushed, added 2L of 70% ethanol, and put into a microwave extraction device for microwave extraction. The extraction power is 500W, and the extraction is performed twice. Combine the extracts for 6 minutes each time, concentrate, add to D101 macroporous adsorption resin column, elute with 50% ethanol, collect 5 times the column volume eluate, recover ethanol unde...
