Problems solved by technology

However, in addition to the determination of citric acid in the original standard, there is no other test for the two traditional Chinese medicines of northern hawthorn and malt in the prescription, and there are neither quality indicators nor identification methods for these quality indicators.
Unscrupulous manufacturers do not strictly follow the dosage of prescriptions in the production of drugs, and wantonly reduce raw materials, resulting in a significant decline in the efficacy of drugs, affecting the safety and effectiveness of drugs, and seriously damaging the interests of patients

Abstract

The invention provides a detection method of pulse-an granules (particle). The detection method comprises projects of identification and content determination, the identification comprises thin layer chromatography of north hawthorn and thin layer chromatography of malt in the pulse-an granules; and the content determination comprises content determination of citric acid in the pulse-an granules. The detection method conducts effective quality control on all traditional chinese medicinal materials in a prescription, can better and comprehensively reflect quality of the pulse-an granule drug, and can effectively prevent illegal manufacturers from producing fake pulse-an granules so as to guarantee safety and efficiency of pharmacy of the masses.

Description

technical field [0001] The invention relates to a method for detecting active ingredients in traditional Chinese medicine prescriptions, in particular to a method for detecting active ingredients in Maian Granules. Background technique [0002] Mai'an Granules (Granules) is a variety recorded in the first volume of traditional Chinese medicine preparations in the "Drug Standards of the Ministry of Health". The standard number is WS3-B-0115-89. The prescription is hawthorn and malt. It is a granule made of pure Chinese medicine agent. It can treat hyperlipoproteinemia, reduce serum cholesterol, prevent atherosclerosis, and also have certain effects on reducing triglyceride and β-lipoprotein. Mai'an Granules are commonly used medicines currently on the market for treating hyperlipoproteinemia, lowering serum cholesterol, preventing atherosclerosis, lowering triglycerides, and lowering β-lipoprotein. However, in addition to the determination of citric acid in the original sta...
