[0027] The present invention also provides a preparation method of frangipani dripping pills, specifically comprising the following steps:
[0028] Step 1. Preparation of frangipani extract: crush the dried frangipani flower and cold-soak for 0.5 h, then add 10-15 times the amount of water for reflux extraction, the reflux extraction temperature is 55-65°C, and the number of extractions is 2-3 times. Combine the extracts for 0.5-2 hours each time, filter, concentrate the filtrate at 75°C and a vacuum of 0.075 MPa to an extract with a relative density of 1.25-1.35, let cool, add 4-6 times 50-80% ethanol, and stir Let it stand evenly for 24-72 hours, filter out the supernatant, recover ethanol under reduced pressure at 75°C and 0.075MPa until there is no alcohol smell, continue to concentrate at 75°C to a thick paste with a relative density of 1.20-1.30, and transfer it to a vacuum drying oven , vacuum-dried to dryness at 60°C and 0.08MPa, and crushed through a 120-140 mesh siev...

[0033] A preparation method for Frangipani dripping pills, specifically comprising the following steps:
[0034] Step 1. Preparation of frangipani extract: crush the dried frangipani flower and cold-soak for 0.5h, add 10 times the amount of water for reflux extraction, the reflux extraction temperature is 55°C, the extraction times are 2 times, each time for 0.5 hours The liquids were combined, filtered, and the filtrate was concentrated to an extract with a relative density of 1.25 at 75°C and a vacuum of 0.075MPa, let cool, added 4 times 50% ethanol, stirred evenly and stood for 24h, filtered out the supernatant, 75°C, Recover ethanol under reduced pressure at 0.075MPa until there is no alcohol smell, continue to concentrate at 75°C to a thick paste with a relative density of 1.20, transfer it to a vacuum drying oven, dry it in vacuum at 60°C and 0.08MPa, and crush it through a 120-mesh sieve , to get the main drug fine powder. During the reflux extraction process, the soli...
