Problems solved by technology

Therefore, the interaction between the various components will have an impact on the composition of the final extract of traditional Chinese medicine, resulting in different proportions of the extract components of traditional Chinese medicine and compatible Chinese medicine. At the same time, the components and proportions of the extract will also vary due to different extraction conditions. Different extracts with different proportions of corresponding ingredients and the effects of different extracted parts will also have differences

Embodiment 1

[0033] Embodiment 1: Preparation of the extract of Hedyotis diffusa, Scutellaria barbata and Prunella vulgaris composition

[0034] Add 30 times of the total amount of Chinese medicine (150g) to 60g of Hedyotis diffusa, 60g of Scutellaria barbata and 30g of Prunella vulgaris, and soak at room temperature for 24 hours to obtain the pretreated Chinese medicine. Boil the obtained pretreated traditional Chinese medicine at 100° C. for 1.5 hours, filter the boiled liquid with 4 layers of gauze, add 15 times of water, boil for 1 hour, filter the boiled liquid with 4 layers of gauze to remove medicinal residues. The two liquid medicines were combined and allowed to stand overnight. The next day, take the supernatant, precipitate centrifugal filtration (3000rpm, 20 minutes), combine all the supernatants, boil and concentrate to 500mL, then concentrate the supernatant to 100mL decoction in a 100°C water bath, and then use 71% The concentrated solution was precipitated with ethanol to ...
