Quality control method of radix cudramiae medicinal materials

Abstract

The invention discloses a quality control method of a radix cudramiae medicinal material, 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 13.0%, the total ash content is not more than 6.0%, the extract is determined by 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 dilute ethanol is used as a solvent and is not less than 10.0%; and (3) thin-layer chromatography identification; wherein inthe chromatogram of the test sample, fluorescent spots with the same color should be shown at the position corresponding to the chromatogram of the kaempferol reference substance. The scientific, complete, reliable and effective quality control method for the radix cudramiae medicinal material is established, and the method is high in specificity and good in reproducibility; meanwhile, the qualitystandard of the radix cudramiae 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.
