Abstract

The invention discloses a method for analyzing a night cold flu cough allergy capsule by utilizing HPLC (High Performance Liquid Chromatography). The night cold flu cough allergy capsule contains acetaminophen, phenylephrine hydrochloride, succinic acid doxylamine and dextromethorphan hydrobromide. In the HPLC analysis, an octadecyl silane bonded silica gel column is adopted as a chromatographic column; a sodium 1-octanesulfonate-phosphate buffer solution with the pH of 2.0-3.0 acts as a mobile phase A; acetonitrile and a mixed solution of acetonitrile and methyl alcohol act as a mobile phase B. The method can be simultaneously and effectively used for detecting four effective ingredients in the night cold flu cough allergy capsule, is simple to operate, analyzes rapidly, is good in repeatability, has favorable specificity, and can effectively and comprehensively control the product quality of the night cold flu cough allergy capsule.

Description

technical field [0001] The invention belongs to the technical field of drug analysis, in particular, the invention relates to a method for analyzing aminomethamine II soft capsules by using high performance liquid chromatography. Background technique [0002] Cold is one of the most common respiratory diseases. There are many kinds of medicines for treating colds. Western medicines are very popular because of their relatively transparent safety and quick results. Most cold medicines are compound preparations. For Western medicine, the composition of cold medicine mainly includes the following types of drugs: antipyretic and analgesic drugs, adrenergic receptor agonists, antihistamines, antitussive and expectorant drugs, antiviral drugs Wait. Amamimin Ⅱ soft capsule (English name: Night cold flu cough allergy (acetaminophen, dextromethorphan hydrobromide, doxylamine succinate, phenylephrine hydrochloride) capsule) is a cold medicine, each capsule contains acetaminophen 325m...
