Embodiment 1
[0030] Embodiment 1 Preparation of solid fermented product:
[0031] Take astragalus dregs, crush them, pass through a 10-mesh sieve, add water to make the water content of astragalus dregs 52%, put them into 10 culture bottles, and sterilize at 120°C for 2 hours; after cooling, inoculate with 10% ganoderma lucidum, and adjust the temperature Ferment at 27°C for 32 days to obtain a solid fermented product; collect the solid fermented product, dry it at 60°C, measure the water content to 8%, and pulverize it.
Embodiment 2
[0032] Embodiment 2 Preparation of solid fermented product:
[0033] Take astragalus dregs, crush them, pass through a 10-mesh sieve, add water to make the water content of astragalus dregs 45%, put them into 10 culture bottles, and sterilize at 121°C for 1.5 hours; after cooling, inoculate with 5% ganoderma lucidum, and adjust the temperature Ferment at 25°C for 45 days to obtain a solid fermented product; collect the solid fermented product, dry it at 50°C, and pulverize it with a water content of 10%.
Embodiment 3
[0034] Embodiment 3 Preparation of solid fermented product:
[0035] Take astragalus dregs, crush them, pass through a 10-mesh sieve, add water to make the water content of astragalus dregs 60%, put them into 10 culture bottles, and sterilize them at 121°C for 2 hours; It is adjusted to 30°C and fermented for 40 days to obtain solid fermented product; the solid fermented product is collected, dried at 70°C, and pulverized with a water content of 6%.
[0036] The dried pulverized solid fermented product obtained in Example 1 is extracted and separated:
[0037] Take 1 kg of solid fermented product powder, add 70% ethanol extract to reflux extraction twice, each time for 2 hours, combine the 2 extracts, recover ethanol under reduced pressure to a thick paste, and obtain extract. Add an appropriate amount of water to dissolve the extract, shake and extract the aqueous solution for 3 times with n-butanol saturated with water, combine the n-butanol solution, wash fully with 1% NaO...
