Embodiment 1
[0039] Example 1 Preparation method of total astragaloside injection 1 of the present invention:
[0040]Astragalus medicinal material conforms to the relevant regulations under the item of Astragalus membranaceus on page 249 of the first part of the Chinese Pharmacopoeia in 2000, and astragaloside IV in the medicinal material of Astragalus membranaceus was detected by high performance liquid chromatography, and the medicinal material of Astragalus membranaceus contained astragaloside IV (C 41 h 68 o 14 ) shall not be less than 0.06%.
[0041] Take 500 kg of astragalus decoction pieces (2-4mm thick slices, produced in Inner Mongolia), add 8 times the amount of water and decoct three times, 1.5 hours each time, combine the decoction liquid, filter, and concentrate the filtrate under reduced pressure (temperature: 70°C; vacuum degree: -0.08Mpa) to a relative density of 1.15 (measured at 60°C), precipitate with 95% ethanol until the alcohol content reaches 80%, refrigerate and ...
Embodiment 2
[0043] Embodiment 2 The preparation method of total astragaloside injection 2 of the present invention:
[0044] Take 500 kg of astragalus decoction pieces (2-4mm thick slices, produced in Shaanxi Province), add 12 times the amount of water to decoct twice, each time for 2 hours, combine the decoction liquid, filter, and concentrate the filtrate under reduced pressure (temperature: 70°C; vacuum Degree: -0.08Mpa) to a relative density of 1.25 (measured at 60°C), precipitate with 95% ethanol until the alcohol content reaches 90%, refrigerate and stand for 27 hours, filter, take the filtrate to recover ethanol and concentrate to the equivalent of 0.75 grams of crude drug, refrigerated for 36 hours, filtered. Take the filtrate and pass it through the HPD700 macroporous adsorption resin column, wash it with water until it is nearly colorless, elute it with 80% ethanol, collect the eluate, filter it, recover the ethanol and concentrate it to a relative density of 1.15 (measured at 6...
Embodiment 3
[0046] Example 3 The preparation method of total astragaloside injection 3 of the present invention:
[0047] Take 500 kg of astragalus decoction pieces (2-4mm thick slices, produced in Shanxi Province), add 8 times the amount of water and decoct three times, 1.5 hours each time, combine the decoction liquid, filter, and concentrate the filtrate under reduced pressure (temperature: 70 ° C; vacuum degree : -0.08Mpa) to a relative density of 1.25 (measured at 60°C), precipitate with 95% ethanol until the alcohol content reaches 65%, refrigerate and stand for 27 hours, filter, take the filtrate to recover ethanol and concentrate to 0.75 per milliliter gram of crude drug, refrigerated and allowed to stand for 24 hours, filtered. Take the filtrate and pass it through the LD140 macroporous adsorption resin column, wash with water until it is nearly colorless, elute with 75% ethanol, collect the eluate, filter, recover the ethanol and concentrate to a relative density of 1.20 (measur...
