Embodiment 1
[0012] Take 300g of astragalus decoction pieces, put them in a reflux extraction tank, add distilled water to decoct 4 times, decoct with 12 times the amount of water (soaked for 0.5h) for 2 hours for the first time, decoct for 1.5 hours with 8 times the amount of water for the second time, and decoct for 1.5 hours with 8 times the amount of water for the second time Decoct with 6 times the amount of water for 1 hour for the third time, and decoct for 1 hour with 6 times the amount of water for the fourth time, combine the decoction liquid, filter, concentrate the filtrate to 1 g of the original medicinal material per ml, and precipitate with ethanol to make the The alcohol content reaches 70%, refrigerate overnight at 4°C, filter, take the precipitate I and the filtrate I separately, and set aside, the precipitate I is repeatedly washed with ethanol, and dried under reduced pressure at 30-40°C to obtain the extract of astragalus polysaccharide; the filtrate I is recovered Conc...
Embodiment 2
[0014] Take 500g of astragalus decoction pieces, put them in a reflux extraction tank, add distilled water to decoct 3 times, decoct for 2 hours with 10 times the amount of water (soaked for 1 hour) for the first time, decoct for 1.5 hours with 8 times the amount of water for the second time, and decoct for 1.5 hours with 8 times the amount of water for the third time. Decoct with 8 times the amount of water for 1 hour each time, combine the decoction liquid, filter, concentrate the filtrate to 1 g of the original medicinal material per ml, precipitate with ethanol to make the alcohol content reach 75%, refrigerate overnight at 4°C, filter, respectively Take the two parts of the precipitate I and the filtrate I, set aside, wash the precipitate I repeatedly with ethanol, and dry it under reduced pressure at 30-40°C to obtain the extract of astragalus polysaccharide; recover the ethanol from the filtrate I and concentrate it to the equivalent of 10g of the original medicinal mater...
