Quality control method of bauhinia championii medicinal materials

Abstract

The invention discloses a quality control method of bauhinia championii medicinal materials, and relates to the technical field of traditional Chinese medicinal materials. The method comprises the following steps: (1) microscopically identifying medicinal material powder; (2) determining the water content, total ash content and extract content ranges of the medicinal materials: the water content is not more than 15.0%, the total ash content is not more than 9.0%, and the extract content is not less than 15.0% by using dilute ethanol as a solvent according to a hot dipping method under the condition of an alcohol-soluble extract determination method (the general rule 2201 of the four parts of the Chinese Pharmacopoeia 2015 edition); and (3) thin-layer chromatography identification; whereinin the chromatogram of the test sample, fluorescent spots with the same color should be shown at the position corresponding to the chromatogram of the gallic acid reference substance solution. The scientific, complete, reliable and effective quality control method for bauhinia championii medicinal materials is established, and the method is high in specificity and good in reproducibility; meanwhile, the quality standard of the bauhinia championii medicinal material is established by adopting the method, and the internal quality and the medication quality of the medicinal material can be effectively evaluated and controlled.

Description

technical field [0001] The invention relates to the technical field of Chinese medicinal materials, in particular to a quality control method for medicinal materials of Jiulong rattan. Background technique [0002] Jiulongteng is the fresh or dried cane of leguminous plant Bauhinia championii (Benth.) Benth.

AI Technical Summary

Problems solved by technology

The prior art only involves the inspection of the properties of Jiulongteng medicinal materials ("Quality Standards for Traditional Chinese Medicinal Materials and National Medicinal Materials in Guizhou Province"), which is not very pertinent, and it is difficult to achieve the purpose of truly controlling the quality of medicinal materials by using these methods
