Embodiment 1
[0036] 1. Asarum 1 kg is crushed into 2-4 mm sized particles.
[0037] Soak in 2.5 liters of 60% ethanol and boil until slightly boiled for 4 hours, filter the solution to collect the filter residue.
[0038] 3. Boil the filter residue with 15 times of water for 4 hours, collect the solution and discard the residue, repeat the extraction once, centrifuge and combine the extract.
[0039] 4. Add 95% ethanol to the extract until the ethanol concentration reaches 80%, and let stand overnight at 4°C.
[0040] 5. Centrifuge, wash the precipitate twice with ethanol, and dry under low pressure to obtain powdered asarum polysaccharide extract.
[0041] The raw materials Asarum, Panax notoginseng, American ginseng, white fungus, Codonopsis pilosula or lacquer listed in claim 1 can refer to this method to extract polysaccharides. The asarum, notoginseng and white fungus polysaccharide extracts equivalent to 1 g of the crude drugs were combined, dissolved in 20 ml of water to prepare a...
