摘要

介绍了俄罗斯研究人员用于测定药用植物元素组成的x射线光谱分析方法。这篇综述的重点是过去20年在俄罗斯期刊上发表的文章。研究人员利用波长色散x射线荧光(WDXRF)、能量色散XRF (EDXRF)、同步辐射XRF (SRXRF)和全反射XRF (TXRF)光谱法;电子探针微量分析和扫描电镜分析药用植物中常量元素和微量元素的含量。同时测定宏量和微量元素,加上无损样品制备,使XRF光谱法成为鉴定和监测植物化学成分的一种有吸引力的方法,特别是在医疗实践中使用的方法。大多数已发表的研究提供了样品制备和测量程序的全面信息,提出了计量评估,并讨论了获得的结果。然而,一些出版物缺乏必要的方法细节,并且在提出的分析数据中出现印刷错误。

Application of X-ray Spectral Analysis in Russia to Determine  Chemical Elements in Medicinal Plants

Application of X-ray Spectral Analysis in Russia to Determine Chemical Elements in Medicinal Plants

Some methods of X-ray spectral analysis used by Russian researchers to determine the elemental composition of medicinal plants are considered. The review focuses on the articles published in Russian journals over the past 20 years. Researchers utilize wavelength dispersive X-ray fluorescence (WDXRF), energy dispersive XRF (EDXRF), synchrotron radiation XRF (SRXRF), and total reflection XRF (TXRF) spectrometry; electron probe microanalysis, and scanning electron microscopy to analyze both macro- and microelement contents in medicinal plants. The simultaneous determination of macro- and microelements, coupled with nondestructive sample preparation, makes XRF spectrometry an attractive method for identifying and monitoring the chemical composition of plants, especially those employed in medical practice. Most published studies provide comprehensive information on sample preparation and measurement procedures, present metrological evaluations, and discuss the results obtained. However, some publications lack essential methodological details, and misprints in the presented analytical data occur.
