摘要
目的:建立中药紫石英X-衍射Fourier指纹图谱。方法:对10批主产地的紫石英药材X-衍射Fourier图谱进行分析,建立中药紫石英X-衍射Fourier指纹图谱,并通过相似度计算,区分紫石英、紫石英混淆品、同种化学试剂CaF2。结果:中药紫石英X-衍射Fourier指纹图谱具有很好的专属性,与紫石英混淆品、同种化学试剂CaF2的X-衍射Fourier图谱区别显著。结论:中药紫石英X-衍射Fourier指纹图谱可全面地、客观地反映出紫石英的内在质量特征,可作为紫石英质量检测与鉴别的手段。
Objective：To establish X-ray diffraction Fourier fingerprint of Fluoritum.Method：The X-ray diffraction Fourier fingerprint of Fluoritum was founded on analysis of 10 batches of Fluoritum from main producing areas.At the same time,Fluoritum,the same type of chemical reagent CaF2 and its adulterants were distinguished by computing their similarity.Results：The X-ray diffraction Fourier fingerprint of Fluoritum is exclusive and significantly different from the same type of chemical reagent CaF2 and its adulterants.Conclusion：The X-ray diffraction Fourier fingerprint of Fluoritum can express objectively its interior quality and be used for the quality inspection and of Fluoritum.
