Problems solved by technology

[0004] "Chinese Pharmacopoeia" 2015 edition of Fangfeng medicinal materials contains content determination items of acteoside and 5-O-methylvisamigoside, etc., which cannot comprehensively evaluate the quality of Fangfeng
At present, most of the fingerprints or characteristic maps of Fangfeng reported in the literature are conventional HPLC methods, and they only focus on the material basis of the original medicinal materials. Most of the index components are fat-soluble components as the research objects, which cannot fully reflect the substances of traditional Chinese medicine decoctions. basic features

Abstract

The invention relates to a construction method and a quality detection method of a UPLC characteristic map of windproof medicinal materials. The construction method includes: reference substance solution preparation: preparing a reference substance solution of a reference medicinal material; preparing a reference substance solution of cichoside and 5-O-methyl visamidol glycosides; preparation of a test solution: taking Fangfeng Medicinal materials, solvent extraction, filtration, and the obtained filtrate was used as the medicinal material test solution; Fangfeng standard decoction was taken, solvent extraction, and filtration, and the obtained filtrate was used as the decoction test solution; Ultra-high performance liquid chromatography detection: Absorb reference medicinal materials for reference The substance solution, reference substance reference substance solution, medicinal material test solution, decoction test solution were injected into a liquid chromatograph, and the obtained medicinal material test sample spectrum and decoction test sample spectrum were compared, and the UPLC characteristic spectrum was obtained. The characteristic map can be used for qualitative and quantitative analysis of the quality of the Fangfeng medicinal material, can ensure the quality of the traditional Fangfeng decoction prepared by using the medicinal material, and is also suitable for detecting the decoction.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a method for constructing a UPLC characteristic map and a method for quality detection of windproof medicinal materials. Background technique [0002] Fangfeng is the dried root of Saposhnikoviadivaricata (Turcz.) Schischk, a Umbelliferae plant, and is commonly used in clinical Chinese medicine. It has the functions of expelling wind and relieving external appearance, eliminating dampness and relieving pain, and relieving spasm. It is mostly used clinically to treat colds and headaches, rheumatic arthralgia, itching of rubella, tetanus, etc. It has strong clinical application value and broad market demand. Relevant compound preparations such as Yupingfeng Granules and traditional Chinese medicine formula granules are widely used in clinical practice. [0003] The clinical use of traditional Chinese medicine is mainly based on traditional decoction. The material basis of tradit...
