摘　　要：目的：建立一种简单、快速、有效的分析不同产地芡实中无机元素含量的方法。方法：采用微波消解-ICP-OES法测定不同产地芡实中无机元素的含量,并运用主成分分析法对其所含元素进行分析和评价。结果：不同产地芡实中含有22~26种无机元素,其中铁（Fe）、锌（Zn）、硒（Se）、铜（Cu）、钼（Mo）、铬（Cr）和钴（Co）为人体必须微量元素;钾（K）、钙（Ca）、钠（Na）、镁（Mg）和磷（P）为人体必须常量元素。主成分分析提取5个因子,用来对不同产地芡实进行综合评价,其综合评价函数为F=0.38828F1＋0.25603F2＋0.07617F3＋0.06860F4＋0.04868F5,结果以江苏高邮、湖南湘西、江苏苏州的芡实样品综合排序较前。结论：ICP-OES法快速、灵敏、准确,可作为芡实中无机元素含量分析的可靠方法,并为芡实的质量控制与安全评价提供科学的参考依据。Objective： To establish a simple,rapid and efficient method for determination of different inorganic elements in Euryale Semen from different habitats. Methods： Inductively coupled plasma-optical emission spectrometry（ICP-OES） was applied to determine inorganic elements in Euryale Semen,and the results were analyzed by principal component analysis. Results： Euryale Semen from different habitats contained the kind of inorganic elements ranging from 22 to 26,including micronutrient elements like Iron,Zinc,Selenium,Copper,Molybdenum,Chrome and Cobalt,as well as macronutrient elements such as Potassium,Calcium,Sodium,Magnesium and Phosphorus. Five factors were extracted and used to comprehensively evaluate Euryale Semen from 20 different habitats covered almost China. The comprehensive function was F = 0. 38828F1＋ 0. 25603F2＋ 0. 07617F3＋ 0. 06860F4＋ 0. 04868F5,which resulted in the top three samples coming from Jiangsu Gaoyou,Hunan Xiangxi and Jiangsu Suzhou respectively. Conclusion： The study indicates that ICPOES is a quick,accurate and sensitive method to determine the contents of inorganic elements in Euryale Semen,which provides scientific and reliable reference for its quality control and safety assessment.
