Abstract

The invention relates to a quality detection method of a medicinal composition for treating cough, dyspnea and chest fullness. The composition consists of pine cones, cotton roots and loquat leaves. The quality detection method comprises: active ingredients pine cones, cotton roots, loquat Identification of leaves, determination of free gossypol residues in cotton roots. Free gossypol is a kind of polyphenolic hydroxyl bis-naphthaldehyde compound, which is a toxic substance that can cause redness, swelling and bleeding, nervous disorders, loss of appetite, weight loss, and affect fertility. On the basis of the original quality standard, the present invention optimizes the identification method, increases the identification of loquat leaves, and measures the residual amount of free gossypol in cotton roots, so that the quality monitoring level of the drug combination for treating cough, dyspnea and chest fullness has been significantly improved. Great improvement, the quality detection method has high accuracy and good stability, and can be effectively used for the quality detection of drug combinations for treating cough, asthma and chest fullness, and improves the quality standard.

Description

technical field [0001] The invention relates to the field of medical inventions, in particular to a quality detection method for a combination of medicines for treating cough, dyspnea and chest fullness. Background technique [0002] This product is composed of pine cones, cotton roots, and loquat leaves; among them: pine cones have the effects of eliminating phlegm, relieving cough, relieving asthma, chronic bronchitis, asthma, and coughing with excessive phlegm. Cotton root has the functions of relieving cough, eliminating phlegm and relieving asthma, but a toxic substance free gossypol may remain in cotton root. Free gossypol is a polyphenolic hydroxyl bis-naphthaldehyde compound, which can cause redness, swelling, bleeding, nervous disorders, Loss of appetite, weight loss, affect fertility. Loquat leaves have the effects of clearing the lung and relieving cough, harmonizing the stomach and diuresis, and quenching thirst. It has the effect of treating phlegm cough due t...
