Abstract

The invention discloses a quality control method for antitussive loquat syrup. In the method, an HPLC method is established for content determination of amygdalin, albanin B and phyllotine. The invention overcomes the defects in the prior art that only one or two components of a single Chinese herbal medicine are detected in the content control of the cough loquat syrup, the quality control is single, and the indicators are few, and it is difficult to fully reflect the quality status of the medicinal flavor and components. , combined with actual production efficiency. The quality control method of the present invention is reasonable in design, accurate and reliable, strong in specificity and simple in operation, can effectively control the drug quality in the production, circulation and use of the product, ensure the controllable production process, and ensure the safety of clinical use. The stable curative effect provides a reliable guarantee.
