Abstract

The invention relates to a method for preparing tablets for treating rhinitis. The method comprises the following steps of: performing microwave extraction on siberian cocklour fruit (stir-bake to yellowish) and angelica dahurica, purifying by using a macroporous absorption resin, and performing six-level countercurrent extraction by using an acetone-ethyl acetate mixed solution to obtain siberian cocklour fruit and angelica dahurica extract; performing CO2 supercritical extraction on biond magnolia flower, asarum, scutellaria baicalensis, unibract fritillary bulb, and fermented soybean to obtain supercritical extract; and mixing the siberian cocklour fruit and angelica dahurica extract and the supercritical extract, adding menthol crystal, mixing uniformly, and tabletting. The prepared tablets for treating rhinitis are convenient to take.

Description

technical field [0001] The invention relates to a preparation method of medicine, in particular to a preparation method of traditional Chinese medicine. Background technique [0002] Biyanling Tablets are made from cocklebur (stir-fried yellow), magnolia, angelica, asarum, scutellaria baicalensis, fritillaria, tempeh, and menthol as raw materials. The second volume, penetrating the orifices, reducing swelling, expelling wind and reducing fever. It is used for chronic sinusitis, rhinitis, nasal congestion, headache, turbid nasal odor, and loss of sense of smell. [0003] In the prior art, there is no report on the choleretic effect of Biyanling Tablets. [0004] In the prior art, Biyanling Tablets are prepared by decocting in water. The process is rough and outdated, and there are many impurities, which leads to excessive daily dosage for patients and is inconvenient to take, seriously affecting the clinical application of this product. Contents of the invention [0005...
