摘    要:针对目前螺旋藻产品质量优劣不一的现状,首次联用PXRD和XRF技术,对不同厂家螺旋藻产品的元素含量和整体特征进行了测定和分析。结果表明:3种片剂中均添加了部分晶体乳糖;根据3种片剂中Si含量比原粉的Si平均值分别增加了8.09、14.68、12.64倍的差异,可知片剂中均添加了微量的硅胶;样品4中微量元素Ca、Fe、Zn的含量明显优化。两种方法的联用可以表达和鉴别螺旋藻产品的内在品质,也能用于可制成粉末样品的其他保健品的鉴别、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。

关 键 词:螺旋藻  X射线衍射(PXRD)  X射线荧光光谱(XRF)

Abstract:For the first time PXRD and XRF were used to test and analyze Spirulina which was produced by different companies.The results indicate that three troches had a portion of crystal lactose.Compared with the original powder,the content of Si in the three troches increased by 8.09,14.68,12.64 times respectively.Accordingly,they were added with a little amount of silica gel.The content of trace element such as Ca,Fe,Zn in sample 4 have optimized clearly.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 Spirulina,can identify and characterize the heath foods and can apply in products' appraisal norm research.
Keywords:Spirulina  X-ray diffraction  X-ray fluorescent analysis
