中文摘要：

建立了刺梨Rosa roxburghii和无籽刺梨Rosa sterilis中微量元素的分析方法。采用微波消解-电感耦合等离子体发射光谱法（ICP-OES）测定了Al、B、Ba、Ca、Cu、Fe、K、Mg、Mn、Na、Ni、P、S、Sr、Zn共15种元素。结果显示各元素在质量浓度范围0~10 mg/L内线性良好,相关系数R≥0.999 1,仪器的检出限为0.000 1~0.006 1mg/L,精密度实验相对标准偏差为0.3%~2.7%,加标回收率为93.3%~107.7%。利用该方法分析了国家标准物质黄芪（GBW10028）,结果与证书值相符。该方法可快速、准确地测定刺梨和无籽刺梨中微量元素。

英文摘要：

We have established a method for determination of the trace elements within Rosa roxburghii and Rosa sterilis Fruits in this study. The contents of 15 elements（ Al,B,Ba,Ca,Cu,Fe,K,Mg,Mn,Na,Ni,P,S,Sr,Zn） were determined by ICP-OES with microwave digestion. The linear ranges of the elements were ranged from 0 ~ 10 mg / L with a correlation coefficient more than 0. 999 1. The detective limits of the instrument were ranged from 0. 000 1 ~ 0. 006 1 mg / L,precision experiments showed RSD ranged from 0. 3% ~ 2. 7% and the recoveries of the elements were in the range of 93. 3% ~107. 7%. Such method was used to test the national standard substance Astragalus membranaceus（ GBW10028）,and the result was consistent with the certificate value. Therefore,this method can be used for quickly and accurately measuring trace elements within Rosa roxburghii and Rosa sterilis Fruits.
