Embodiment 1
[0057] Embodiment 1: preparation embodiment
[0058] (1) Take 5000g of Anhui-produced Phyllostachys praecox leaves, and detect by HPLC method that the content of original opioid is 0.65%, allocryptine 0.12%, sanguinarine 0.15%, and chelerythrine 0.08%, with 20L not less than 80% The 0.5% sulfuric acid solution at ℃ was used for percolation, and sodium hydroxide was added to the percolation liquid to adjust pH=10 to alkali precipitation, and the obtained precipitate was vacuum-dried under reduced pressure. Allocryptine 0.3%, sanguinarine 0.18%, chelerythrine 0.12%.
[0059] (2) Take 1000 g of Coptis Rhizoma, pulverize it, and extract twice with 10 times the amount of 70% ethanol under reflux for 2 hours, then concentrate and dry the extract under reduced pressure to obtain 285 g of Coptidis Rhizoma extract; 28% of berberine hydrochloride was detected by HPLC method.
[0060] (3) Take 1000 g of dandelion, pulverize it, and extract twice with 10 times the amount of 80% ethanol u...
Embodiment 2
[0063] Embodiment 2: preparation embodiment
[0064] (1) Get 5000g of Anhui-produced fallen leaves, detect by HPLC method 0.65% of the original opioid content, 0.12% of allocryptine, 0.15% of sanguinarine, 0.08% of chelerythrine, and use 20L of 5% sulfuric acid solution Heated and refluxed at 100°C for extraction, added KOH to the extract to adjust pH=10 to alkali precipitation, and the resulting precipitate was air-dried to obtain 1750 g of extract. The content of pro-opiate was 1.18%, allocryptine was 0.26%, and sanguinarine was detected by HPLC. 0.16%, chelerythrine 0.10%.
[0065] (2) Take 1000 g of Coptidis rhizome, pulverize it, and extract 3 times with 8 times the amount of 65% ethanol under reflux for 1 h, then concentrate and dry the extract under reduced pressure to obtain 320 g of Coptidis rhizome extract; 31% berberine hydrochloride was detected by HPLC method.
[0066] (3) Take 1000 g of dandelion, pulverize it, and extract 3 times with 6 times the amount of 75% ...
Embodiment 3
[0069] Embodiment 3: preparation embodiment
[0070] (1) Get 5000g of Anhui-produced Phyllostachys abaculi, and detect by HPLC method that the original opioid content is 0.65%, allocryptine 0.12%, sanguinarine 0.15%, chelerythrine 0.08%, and use 20L 0.1% hydrochloric acid solution Soak at room temperature for 48 hours, add Ca(OH) to the extract 2 Adjust the pH to 10 for alkali precipitation, and microwave-dry the obtained precipitate to obtain 2050 g of the extract. The HPLC method is used to detect that the content of protopine is 0.98%, allocryptine is 0.22%, sanguinarine is 0.15%, and chelerythrine is 0.09%.
[0071] The extraction method of Coptidis Rhizoma extract and Dandelion extract in this embodiment is the same as that in Example 1. The percentages of the above substances are all percentages by mass.
[0072] Then in the step (1), the Boluohui leaf extract, Coptidis Rhizoma extract, and Dandelion extract were mixed at a ratio of 50%:30%:20% by mass, and the mixture...
