Abstract

The invention discloses a preparation method of the active part of Xingbei Zhike Granules, which comprises the following steps: weighing the raw materials according to the weight ratio of the compound: taking the raw materials of ephedra ephedra, peucedanum, fritillary fritillary and Baibu four flavors, adding 4 ‑8 times the amount of 50‑80% ethanol was refluxed for 1‑3 hours, filtered, and the filtrate was concentrated under reduced pressure to obtain a clear paste; platycodon grandiflorum, Adenophora, wood butterfly, licorice and bitter almond, boiled for 1‑3 hours, filtered, The filtrate is concentrated under reduced pressure to obtain a clear paste; the above two clear pastes are combined, mixed uniformly, purified by a non-polar macroporous resin chromatography column, and used as water, 20-35% ethanol solution, and 60-95% ethanol solution. The eluent is used to elute the resin column, and 60‑95% ethanol eluate is collected. The method provided by the invention can solve the technical problems of Xingbei Zhike Granules in the prior art, such as single dosage form, large dosage, low active ingredient content, inconvenient clinical use, etc., can reduce production costs, and improve the transfer rate of active ingredients, so it is more effective Suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of pharmacy, and in particular relates to an extraction method of active parts of Xingbei Zhike Granules and its application in the preparation of medicines for treating cough, and belongs to the technical field of extraction methods of active parts of traditional Chinese medicine compound. Background technique [0002] Cough refers to a disease characterized by exogenous pathogenic factors or internal injuries, leading to loss of ventilation and depletion of the lungs, upward reversal of lung qi, impingement on the airway, coughing sound or accompanied by expectoration. Exogenous cough is caused by exogenous six evils; internal injury cough is caused by internal injury factors such as diet and emotions, which cause dysfunction of viscera and internal pathogens. Exogenous cough and internal injury cough are both caused by pathogenic factors that cause lung qi to be unclear and lose Xuansu, and cough due to forced qi u...
