Embodiment 1
[0022]50kg of traditional Chinese medicine Astragalus, sliced, decocted 3 times with 10 times of water for 1 hour each time, filtered, combined with water decoction, passed through a D201 macroporous resin column, washed with 200 liters of water and 100 liters of 30% ethanol in turn to remove impurities, and then used 200 liters of ethanol with a volume content of 70% were eluted, and the ethanol eluate was collected, and the ethanol was recovered under reduced pressure. The residue was dissolved in water, the aqueous solution was extracted with 20 liters of n-butanol in portions, the n-butanol extracts were combined, washed twice with 10 liters of 2% aqueous sodium hydroxide solution, and then washed with 5 liters of water for 2 times. After recovering the n-butanol Dry, pulverize, degrease with 500 ml of acetone in a Soxhlet extractor, and dry to obtain astragalus saponins. Detected by the above method, the content of astragaloside IV is greater than or equal to 20%.

Embodiment 2
[0025] 100kg of traditional Chinese medicine Astragalus, sliced, add water 15 times to decoct twice, 1.5 hours each time, filter, combine the decoction, pass through AB-8 macroporous resin column, wash with 400 liters of water and 200 liters of 40% ethanol in turn to remove impurities , and then eluted with 400 liters of 80% ethanol and collected the ethanol eluate. The eluate was recovered under reduced pressure with ethanol, dissolved in water, and its aqueous solution was extracted with 40 liters of n-butanol in fractions, and the n-butanol extracts were combined and washed with 30 liters of ammonia test solution (40 ml of concentrated ammonia water and water to make 100 ml) in fractions. After recovering n-butanol, it is dried, pulverized, and then degreased with 2000 ml of acetone under stirring and refluxing. After cooling, filter, wash with appropriate amount of acetone, and dry to obtain astragalus saponins. The content of astragaloside IV was detected to meet the req...
Embodiment 3
[0028] 100kg of traditional Chinese medicine Astragalus, sliced, decocted 3 times with 10 times of water, 1 hour each time, filtered, combined with the decoction, passed through a DM-301 macroporous resin column, washed with 400 liters of water and 200 liters of 30% ethanol in turn to remove impurities Afterwards, eluate with 400 liters of 75% ethanol and collect the ethanol eluate. After the ethanol was recovered under reduced pressure, water was added to dissolve, and the aqueous solution was extracted with 40 liters of n-butanol in fractions. After combining the n-butanol extracts, wash with 20 liters of a 5% aqueous sodium carbonate solution, and then wash with 20 liters of water. After recovering n-butanol from the extract, it is dried, and then 1000 ml of acetone is used in a Soxhlet extractor to reflux and degrease, and then dried to obtain astragaloside. The content of astragaloside IV was detected to meet the requirements.
