摘要
目的:利用性状鉴别与X射线衍射(XRD)技术结合的方法对6种白色结晶型矿物类中药进行分析、鉴别.方法:试验采集白矾(明矾)、硼砂、大青盐、芒硝、秋石及白硇砂共15批样品,测定XRD图谱,对图谱进行物相检索,解析各样品的物相组成,总结样品图谱特征,并与性状特点对比分析.结果:6种药材性状上具有较多相似之处,它们均为透明或白色半透明结晶体,具玻璃样光泽且质地硬而脆;区别主要在于形状、色泽及透明度的细小差异.通过解析其XRD图谱,可知该6种矿物药的图谱之间具有直观的差别.这些差别表现在特征峰数量,强峰峰位以及峰形等方面.对该15批药材样品进行聚类分析,结果显示聚类分析可将6种白色结晶型矿物药区分开.结论:性状鉴别与XRD图谱分析结合的方法可准确鉴别白矾、大青盐、硼砂、芒硝、秋石及白硇砂6种白色结晶型矿物类中药,该方法快速有效.
Abstract
Objective:To analyze and identify six white crystal mineral Chinese medicines by using morphological identification and X-Ray diffraction (XRD) technique.Method:In the experiment,15 batches of samples including Alumen,Borax,Halite,Natrii Sulfas,Autumn Mineral and Sal-Ammoniae were collected for XRD patterns.The phase identifying was conducted for the patterns;phase compositions of the samples were analyzed;the characteristics of the samples patterns were analyzed and compared with property characteristics.Result:Six Chinese medicines were similar in properties,because all of them were transparent or white translucent crystal,with glass like luster and a hard and brittle texture;but with little differences in shape,color and transparency.XRD patterns of these 6 mineral medicines showed intuitive differences,which could be reflected in number of peaks,strong peaks positions and peak shape,etc.Cluster analysis results of these 15 batches of herbs showed that 6 white crystal mineral Chinese medicines can be distinguished by cluster analysis.Conclusion:The combining method of X-ray diffraction analysis and morphological identification could be used for the quick and effective identification of six white crystal mineral Chinese medicines:Alumen,Borax,Halite,Natrii Sulfas,Autumn Mineral and Sal-Ammoniae.
