The invention relates to the technical field of
pharmacy, and provides a preparation process of
tendon-relaxing and detoxifying granules, which comprises the following steps: step 1, decocting medicines, and adding water for decocting; step 2, adding conventional decoction medicines, decocting, and then filtering to obtain filtrate for later use; step 3, taking
medicine residues in the step 2, adding water, decocting, adding
uncaria, decocting, and filtering to obtain filtrate for later use; step 4, mixing the
medicine liquid in the step 2 and the
medicine liquid in the step 3, concentrating under reduced pressure to obtain thick paste,
drying under reduced pressure, crushing, and sieving with a 60-mesh
sieve to obtain medicine
powder; and 5, taking other auxiliary materials, uniformly mixing, adding the medicinal
powder in the step 4, uniformly mixing, and granulating. By optimizing the extraction efficiency, the
gastrodin content reaches 34.717 mg / g, the
astilbin extraction rate reaches 5.944 mg / g, the particle performance is greatly improved, the forming rate is improved to 93.97% from 83.95%, the particle
dissolution time is shorter than 5 minutes, and the requirements of pharmacopeia are met. The 80%
ethanol wetting agent reduces the
moisture absorption rate to 9.60% and improves the storage stability. And multi-component collaborative optimization is realized through an AHP-EWM weight method.
