Embodiment 1
[0028] (1) Take 10kg of dry and clean whole dandelion herb, crush it into a coarse powder, add 100kg of methanol with a concentration of 65%, soak for 8 hours, heat and extract at 80-95°C for 5.5 hours, filter the extract, and add the filter residue 100kg of methanol with a concentration of 60%, heating and extracting at 80-95°C for 3.5 hours, filtering the extract, combining the reflux extract, filtering, and recovering the methanol from the filtrate, in a vacuum of -0.085MPa and a temperature of 60°C Concentrate under vacuum to form a thick paste methanol extract; further add the above filter residue to 50kg of pure water, heat to 90-100°C for reflux extraction for 5h, filter, and depressurize the filtrate at a vacuum degree of -0.075MPa and a temperature of 65°C Concentrate to a thick paste water extract; combine methanol extract and water extract, stir evenly, and vacuum dry to obtain dandelion extract;

Embodiment 3
[0036] (1) Take 10kg of dry and clean dandelion whole herb, crush it into coarse powder, add 100kg of methanol with a concentration of 65%, soak for 8 hours, heat at 80-95°C for 4.5 hours, filter the extract, and add the residue 100kg of methanol with a content concentration of 60%, heating and heating at 80-95°C for 4.5 hours, filtering the extract, combining the reflux extract, filtering, and recovering the methanol from the filtrate. Vacuum concentration at 62°C to form a thick paste methanol extract; further add the above filter residue to 50kg of pure water, heat to 90-100°C for reflux extraction for 5 hours, filter, and filter the filtrate at a vacuum degree of -0.08MPa and a temperature of 63°C Concentrate under reduced pressure to a thick paste water extract; combine the methanol extract and water extract, stir evenly, and vacuum dry to obtain the dandelion extract;
[0037] (2) Take 10kg of dry and clean honeysuckle, crush it into a coarse powder, add 100kg of methano...
