Embodiment 2
[0083] Example 2 Extraction process of astragalus saponins and astragalus polysaccharides of the present invention
[0084] Precisely weigh 10 grams of astragalus powder (passed through a No. 2 sieve), put it in a microwave extraction device, microwave power 900W, keep the temperature at 70°C, extract 3 times in total, add 158mL of 50% ethanol for the first time, and extract for 10 minutes; the second time Add 140mL of 50% ethanol solution and extract for 10min; add 140mL of distilled water for the third time and extract for 20min. Put the extraction solution in a suction filtration device for suction filtration, transfer the first two extractions to a rotary evaporator, concentrate to a certain volume, add the third extraction, concentrate to about 60mL, add distilled water to a 100mL volumetric flask, and use phenol-sulfuric acid method The content of astragalus polysaccharide in the extract was determined to be 1.720g, the yield was 18.49%, and the extraction rate was 65.32...
