Embodiment 1
[0038] The preparation of embodiment 1, mountain ramie extract--JM
[0039] First take 0.36 kg of ramie root, add 3.6 kg of water, and soak for 2 hours. Then decoct at 100°C for about two hours, and then filter to obtain a decoction. Add 2.2 kg of water to the medicinal materials, decoct at 100°C for about two hours, and then filter to obtain another decoction. The two decoction filtrates were mixed, then concentrated under reduced pressure to 0.218kg, and the measured solid content was 15.3%. A total of 33 g of the product JM was obtained after freeze-drying.
Embodiment 2
[0040] Embodiment 2, the preparation of ramie extract--BMEC-1
[0041] Take 15 kg of ramie roots, add 150 kg of water, and soak for 8-16 hours. After decocting at 100°C for two hours, filter to obtain a decoction filtrate. Then add 150 kg of water to the medicinal materials, decoct at 100°C for two hours, and filter to obtain the second decoction filtrate. Then the above two decoction filtrates were combined to obtain 266 kg of decoction, which was then concentrated under reduced pressure to 8.3 kg, and the solid content rate was recorded to be 17.6%. Stir the concentrate and add 15 L of 95% ethanol for alcohol precipitation using a peristaltic pump. Finally, a centrifuge was used to separate the alcohol precipitation solution, and the supernatant was collected, concentrated under reduced pressure, and freeze-dried to obtain the product BMEC-1, a total of 1.013 kg.
Embodiment 3
[0042] Embodiment 3, the preparation of ramie extract--BMEC-101
[0043]First take 95 kg of ramie roots, add 800 kg of water, and soak for 8 to 16 hours. After decocting at 100°C for 2 hours, filter to obtain the first decoction filtrate; then add 700 kg of water to the medicinal materials, and then decoct at 100°C for 2 hours, filter to obtain the second decoction filtrate; combine the first decoction filtrate and the second decoction filtrate to obtain Decoction 1340kg, then concentrated under reduced pressure to 42kg (the first concentrated solution), the solid content rate was measured to be 25%; then the concentrated solution was stirred and 70L of 95% ethanol was added using a peristaltic pump for alcohol precipitation; using a centrifuge Centrifuge the alcohol precipitate, collect the supernatant, concentrate under reduced pressure to 12.5kg (the second concentrated solution), and record a solid content rate of 15%; then the second concentrated solution is centrifuged t...
