Abstract

The invention discloses an establishment method for an HPLC (high performance liquid chromatography) fingerprint of a cold treatment medicament. The method comprises the following steps: (1) preparing reference solvents: preparing glycyrrhizic acid, liquiritin, chlorogenic acid and cynaroside reference solvents respectively; (2) preparing a test solvent: weighing bitter sweet granules, performing extraction, and filtering an extracting solvent with a microfiltration membrane to obtain the test solvent; (3) performing measurement to obtain the fingerprint by adopting an HPLC method, wherein a chromatographic condition is gradient elution, a flowing phase A of gradient elution is acetonitrile, B is a 0.05 to 5 percent formic acid aqueous solvent, and the detection wavelength is 254nm; (4) evaluating the similarity: evaluating the fingerprint of a test sample by adopting the Similarity Evaluation System for Chromatographic Fingerprint of TCM (Version 2004 A). the method is high in precision, repeatability and stability, and the quality of the bitter sweet granules can be effectively controlled by adopting an HPLC fingerprint technology.

Description

technical field [0001] The invention relates to a quality control method of a medicine for treating colds, in particular to a method for establishing an HPLC fingerprint of a medicine for treating colds. Background technique [0002] Chinese patent medicine for cold medicine is a complex system composed of multiple components, multiple factors, and multiple targets. The diversity and complexity of its chemical components are the material basis for its curative effect. The problem of analysis and evaluation, improving the existing quality control methods of traditional Chinese medicine is the focus and difficulty of attention in recent years. [0003] At present, most of the quality testing methods of traditional Chinese medicine still use spectral or chromatographic methods to identify or measure one or several active ingredients or index ingredients, as well as the routine inspection items stipulated in the Pharmacopoeia. For traditional Chinese medicine, the content of an...
