摘要
目的:确定道地产区湖北应城石膏X-射线衍射专属特征峰。方法:应用X-射线衍射方法,对不同产地中药石膏进行指纹图谱分析,确定共有峰;并对道地产区湖北应城石膏的特征峰进行专属性鉴别。结果:获得不同产地石膏X-射线衍射指纹图谱,确定16个平均值共有峰;道地产区湖北应城产淡黄色纤维状石膏,其X-射线衍射图谱中具有两个专属特征峰,晶面间距(d)分别为1.68与1.51。结论:道地产区湖北应城石膏X-射线衍射专属特征峰的确定,可区别其他产地石膏,为进一步评价中药石膏的品质提供依据。
Objective:To analyze the characteristic peaks of gypsum fibrosum from authentic product area Hubei Yingcheng via X-ray diffraction. Methods:The fingerprint and common peaks of gypsum fibrosum from different areas were analyzed via X-ray diffrac-tion, and the characteristic peaks of gypsum fibrosum from authentic product area Hubei Yingcheng were identified Results:The finger-prints of X-ray diffraction of gypsum fibrosum from different areas were obtalned. Sixteen common peaks were determined, and two characteristic peaks of gypsum fibrosum from authentic product area Yingcheng were determined via X-ray diffraction with interplanar spacing of 1. 68 and 1. 51, respectively. Conclusion:The determination of two characteristic peaks of gypsum fibrosum from authentic product area Hubei Yingcheng can distinguish gypsum fibrosum from the other areas and provide basis for the quality evaluation of gyp-sum fibrosum.
