Embodiment 1
[0012] Wash the freshly collected Liu Jinu herbs, cut them into 1cm-long sections, add water 0.5 times the weight of the herbs, stir for 15 minutes, and squeeze the juice while it is fresh. Add 2 times the amount of tap water to the obtained medicinal dregs, stir for 20 minutes, and press with a plate-and-frame filter press to extract the juice. The obtained medicinal dregs are squeezed with an extruder, and the medicinal juice is filtered. Combine the above three Liu Jinu medicinal juices, filter through a 60-mesh sieve, concentrate the filtrate under reduced pressure, and set the temperature at 60°C. When the relative density of the concentrated extract was 1.10, it was transferred to a -20°C refrigerator and frozen for 12 hours. Freeze drying was carried out after taking out the frozen material, the temperature was set at -18°C, the pressure was 0.09Mpa, and the time was 24 hours. Collect the freeze-dried product, pulverize it, pass through a 60-mesh sieve, pack it into b...
Embodiment 2
[0014] Wash the freshly collected medicinal herbs of Liu Jinu, cut them into 2cm-long sections, add 1 times the weight of the medicinal herbs in water, stir for 30 minutes, and squeeze the juice while it is fresh. Add 5 times the amount of tap water to the obtained dregs, stir for 30 minutes, and press with a plate-and-frame filter press to extract the juice. The obtained medicinal dregs are squeezed with an extruder, and the medicinal juice is filtered. The above 3 Liu Jinu medicinal juices were combined, filtered through a 100-mesh sieve, the filtrate was concentrated under reduced pressure, and the temperature was set at 70°C. When the relative density of the obtained concentrated extract was 1.05, it was transferred to a -20°C refrigerator and frozen for 8 hours. Freeze-dry after taking out the frozen material, the temperature is set at -40°C, the pressure is 0.09Mpa, and the time is 48 hours. Collect the freeze-dried product, pulverize it, pass through a 100-mesh sieve,...
