摘要
目的:考察X射线衍射分析在中药石膏质量检测与鉴别中的应用价值。方法:应用X射线衍射法对中药石膏进行定性分析,并对不同产地的10批纤维状石膏与化学试剂硫酸钙及非纤维状石膏进行分析。结果:石膏X射线衍射图谱具有很好的专属性,与其它含钙矿物药、化学试剂硫酸钙、非纤维状石膏区别明显,10批纤维状生石膏指纹图谱相似度均达到95％以上。结论:石膏的X射线衍射指纹图谱可全面地、客观地反映出石膏的内在质量特征。X射线衍射分析方法专属性强,准确可靠,可作为石膏质量检测与鉴别的手段,
Objective: To investigate the applied value of qualitative determination and distinguish for gypsum with X-ray diffraction. Methods: With X-ray diffraction for qualitative analysis of Gypsum, the fibriform and non-fibroid gypsum and chemical reagent calcium sulfate in 10 group and from different producing areas were analyzied. Results: The X-ray diffraction atlas of gypsum was exclusive and different remarkably from the other mineral medicines including calcium, non -fibroid gypsum and chemical reagent calcium sulfate. All the finger prints of the fibriform gypsum from each group were similar and the comparability was over 95%. Conclusion:The X-ray diffraction can express objectively the interior quality of the gypsum, which is specificity, accuracy and reliability and can be used for the determination of Gypsum.
