Problems solved by technology

However, the curative effect of the drug can only be guaranteed under the premise of quality control, and the existing quality control method of this drug combination is extremely simple and rough, and cannot fully and accurately reflect and control the quality of the compound preparation at all.
The chemical composition of traditional Chinese medicine is complex. Often there are dozens to hundreds of chemical components in each medicinal material, and there are no less than a few known biologically active ingredients. The chemical composition of traditional Chinese medicine compound preparations containing several medicinal materials ingredients are more complex
If only one or two active ingredients are used to illustrate its intrinsic quality, it is somewhat one-sided, not to mention that there is no relevant content determination method in the prior art

Abstract

A quality control method for the Chinese medicine used for treating diabetes and prepared from glibenclamide and 7 Chinese-medicinal materials including pueraria root, rehmannia root, astragalus root, yam, etc features the differentiation test method and/or content measuring method for its multiple components.

Description

technical field [0001] The invention relates to a quality control method of a compound preparation of medicine for treating diabetes, which belongs to the technical field of traditional Chinese medicine. Background technique [0002] The compound preparation of the present invention is a compound preparation made from the traditional Chinese medicine puerarin, rehmannia glutinosa, corn silk, trichosanthin, astragalus, schisandra, yam and chemical drug glibenclamide. It has the effects of nourishing kidney and yin, nourishing qi and promoting body fluid, and is used for polydipsia, polyuria, polyphagia, emaciation, fatigue and weakness, poor sleep and low back pain, urine sugar and elevated blood sugar. The category includes diabetes in modern medicine. According to reports, the total prevalence of diabetes in my country reached 2.4% in 2000, and the total number of diabetic patients in the country has reached nearly 31 million. In addition to the increasing number of diabe...
