Embodiment 1
[0034] Get 1000 grams of belladonna coarse powder, according to the percolation method (two appendix 10 of Chinese Pharmacopoeia version in 2000) under the extract item, soak 20 hours with 80% ethanol, slowly percolate with the speed of 3 milliliters per hour, collect The filtrate was 6000 ml, the ethanol was recovered under reduced pressure, and the liquid extract was stored in a separate container; the dregs were decocted twice, each time adding 6 times of water, and the decoction time was 1 hour each, filtered, and the filtrates were combined and concentrated to a relative density of 1— 1.4, continue to concentrate under reduced pressure to a thick paste after merging and mixing with the liquid extract extracted with ethanol, and measure the atropine content until the atropine content reaches more than 0.5% (g / g).
