Embodiment 1
[0155] (1) Weigh 100g of Angelica sinensis, crush it through a 40-mesh sieve, and use supercritical CO 2 The extraction method extracts the volatile oil, the conditions are: the extraction pressure is 25MPa, the extraction temperature is 40°C, the extraction time is 2h, collect 0.9mL of volatile oil, decoct the dregs with 10 times the amount of water for 2 times, each time for 1 hour, filter, and the filtrate Concentrate to a relative density of 1.4 (normal temperature), add ethanol until the alcohol content reaches 80%, let stand for 24 hours, collect the supernatant and precipitate, dry the precipitate, add water to dissolve, filter, and concentrate the filtrate to a relative density of 1.3 ( normal temperature), add ethanol for precipitation to make the alcohol content reach 70%, let stand for 24 hours, and dry the precipitate to obtain 14.1g of Angelica sinensis polysaccharide extract; the supernatant is decompressed to recover ethanol, concentrate, and put on AB-8 type mac...
