specific Embodiment 1
[0078] Rhubarb is excavated at the end of autumn when the stems and leaves are withered or before they germinate in the next spring, remove the fine roots, scrape off the outer skin, cut the petals or segments, thread them into strings and dry them or directly dry them, chop them and soak them in 5-10 times the amount of ethanol In the process, put the medicinal powder in a stainless steel barrel with a cover, add 70% ethanol solution, the mass is 0.8-1 times that of the coarse powder, stir evenly, and keep it moist and airtight for more than 1 hour to fully expand; the filter plate at the bottom of the percolation cylinder is covered with gauze After the bag is wrapped and paved, mix the wet and expanded drug samples loosely, then use a stainless steel spoon to fill the powder, evenly put it into the percolation cylinder, fill it with a thickness of 10-12 cm, press it evenly with a T-shaped stick, and then press the above Operation, loading layer by layer, proper pressure, the...
specific Embodiment 2
[0081] Excavate at the end of autumn when the stems and leaves are withered or before they germinate in the next spring, remove the fine roots, scrape off the outer skin, cut the petals or segments, thread them into strings and dry them directly, take the raw rhubarb cut into small pieces, mix well with rice wine, put Steam it in a steamer, or put it in a pot and seal it, sit in a water pot, steam it thoroughly, take it out and dry it in the sun, and steam it 2 to 3 times according to the above method. After drying and ripening 5000g of rhubarb, soak it in 10 times the amount In ethanol, heat and extract twice, each time for 1-2 hours, remove the supernatant, combine the extracts, filter through 100-120 mesh, and then ultrafilter through an ultrafiltration column with a cut-off molecular weight of 5000-10000, and the ultrafiltrate reduces Concentrate the extract with a relative density of 1.06 at 80°C under pressure, concentrate by heating until it is in the form of a paste, le...
