摘要
目的:建立金莲花中药材内在质量的快速鉴别方法。方法:采用 X 射线荧光分析方法(XRF)和粉末 X 射线衍射技术(PXRD)对5个不同来源及产地金莲花样品的元素含量和整体特征进行了测定和分析。结果:5个样品中钾和钙元素含量均较高;而微量元素含量差异较大;道地品中富含钾元素的晶态物质含量最高,晶粒尺寸却最小,约40 nm。结论:首次在金莲花中发现了富钾相。2种方法的联合应用不仅可以表达和鉴别药材的产地特征及识别其优劣;也能用于可制成粉末样品的中成药的鉴别、表征和质量控制,而且在质量标准的研究及制定方面具有广阔应用前景。
Objective：The elemental compositions of Flos Trollii were analyzed quantitatively with modern apparatus Methods.The five samples of Flos Trollii from different producing areas were analyzed and characterized with X- ray fluorescent and X - ray powder diffraction analysis. Results： The contents of kalium and calcium all are higher in the five samples,the difference of the contents of microelement being obvious in each sample, the content of biologic crystalloid being the highest and the size of minicrystal being the least （approximate 40 nm） in the local herb. Conclusions： First discovered the contents of biologic - crystalloid kalium, the united fashion of the method of X - ray powder diffraction and the method of X - ray fluorescent analysis can express and distinguish the producing area characters and quality of medicinal materials, can identify and characterize the patent medicine and can apply in products＇ appraisal norm research.
