Problems solved by technology

However, these quality control methods disclosed in the prior art need to classify the ingredients in the stagnation-dissolving analgesic drugs by different methods, and then measure them separately or by classification, resulting in a single type of ingredients that can be detected simultaneously at one time, and often the quantity is relatively large. The purpose of quickly and efficiently evaluating the quality of drugs cannot be achieved; in addition, the pretreatment process of existing detection methods is usually complicated, and consumes a lot of reagents and manpower

Abstract

A method for detecting a stasis-removing pain-relieving medicine is disclosed. The method includes 1) mixing the stasis-removing pain-relieving medicine with a solvent, and performing extraction to obtain a solution of a test product; 2) detecting the solution of the test product by liquid chromatography-mass spectrometry to obtain a fingerprint; and 3) according to the fingerprint, a standard curve and the mass of the test product of the medicine, acquiring contents of fourteen components in the test product. A UPLC / Q-TOF MS manner is adopted in the method, and negative-positive ion full-scanning mode is adopted, and therefore a plurality of compounds can be effectively distinguished, components of the medicine are qualitatively and quantitatively detected, and the components of fourteen different types in the medicine can be detected. The method has characteristics of simple sample treatment operation, a low sample using amount, high precision, capability of being accurate and rapid, high stability, good repeatability and a high recovery rate, and can be adopted as an effective detecting method at present for comprehensively controlling quality of the stasis-removing pain-relieving medicine.

Description

technical field [0001] The invention relates to the field of drug analysis, in particular to a detection method for stagnation-dissolving and analgesic drugs. Background technique [0002] The analgesic medicine for dispelling stagnation is a prescription preparation composed of Panax notoginseng, dragon's blood jellyfish, fritillary fritillary and coix seed. Secondary dysmenorrhea, irregular menstruation, pelvic mass, infertility, endometriosis and other diseases have a good curative effect on endometriosis in clinical use. The main components of stagnation-relieving and analgesic drugs are saponins, phenolic acids, alkaloids and oils, etc. These ingredients are crucial to the efficacy of stagnation-relieving and analgesic drugs. In order to better control the quality of medicines and ensure the clinical efficacy of medicines, it has become a research hotspot in this field to detect the related components of stagnation-relieving and analgesic medicines and to establish a m...
