Abstract:
Objective To explore the determination method of copper content in Chinese medicinal materials and to provide a scientific basis for the quality control of Chinese medicinal materials.Methods A method for rapid determination of copper content in different varieties of Chinese medicinal materials by X-ray fluorescence spectrometry was established.Results The content of copper in the linear range of 6-40 μg·g-1 showed good linearity with the response strength,which met the quantitative analysis requirements.Conclusion This method has the advantages of being simple,fast,and highly sensitive,and it can be used for rapid quality control of copper content in Chinese medicinal materials.
