摘要

Trollius chinensis Bunge formula granules and a preparation method therefor. The preparation method comprises: mixing a Trollius chinensis Bunge medicinal material with an ethanol aqueous solution at a volume ratio of 1:12‑15; performing reflux extraction 1-3 times; filtering; concentrating the filtrate under reduced pressure to obtain a concentrated solution having a relative density of 1.1‑1.15; mixing the concentrated solution with a pharmaceutically acceptable auxiliary material; drying; collecting a dried paste powder; crushing through a 80-mesh sieve; placing in a mixing tank and mixing; granulating the obtained Trollius chinensis Bunge dried paste powder; sieving the granules sequentially by using a 20-mesh sieve and a 50-mesh sieve so as to obtain Trollius chinensis Bunge formula granules. The Trollius chinensis Bunge formula granules prepared by using the described method have a high content of active components and have uniform particle size.
