Abstract

The invention provides a quality detection method for lung-soothing syrup. The method comprises part or all of properties, inspection, identification and content measurement items, wherein the properties need to satisfy relevant regulations under Section Syrup; in the inspection, the syrup needs to conform to the relevant regulations in Section Syrup, Appendix IH, Part 1, Chinese Pharmacopedia (2005 Edition); in the component identification, ammonium chloride and licorice are identified; and in the content measurement, the content of ephedrine hydrochloride and the content of ammonium chloride are measured. The quality detection method has the advantages of high precision, high stability, favorable reproducibility, high recovery rate and accurate measurement result, enhances the quality control standard of lung-soothing syrup, and can effectively control illegal manufacturers from producing fake and poor-quality lung-soothing syrup, thereby ensuring the clinical curative effect of the preparation.

Description

technical field [0001] The invention relates to a detection method for Shufei syrup, which belongs to the technical field of quality control of medicines. Background technique [0002] Shufei syrup is a variety recorded in the twelfth volume of traditional Chinese medicine preparations in the "Drug Standards of the Ministry of Health". The standard number is WS3-B-2439-97. The prescription is ammonium chloride, ephedrine hydrochloride, licorice Bubu liquid extract and Platycodon grandiflorum liquid extract are compound syrups of Chinese and Western medicines. It has the effect of antitussive and expectorant, clinically used in the treatment of respiratory diseases such as acute and chronic bronchitis, cough, asthma, phlegm, etc. Common medicines for respiratory diseases. However, the existing technology does not carry out quality control on several important components wherein, ephedrine hydrochloride, which has the effect of relieving cough and relieving asthma, is a chem...
