摘要
采用电感耦合等离子体质谱仪（ICP-MS）测定了栽培甘草中的十种微量元素。结果表明，方法中各元素标准曲线的r^2值均在0.99以上，回收率为91.21％～108.65％，RSD值为3.6％～8.9％’。该法精密度高、准确性好、干扰较少、快速简单，可用于甘草中微量元素的含量测定。
The content of ten elements in cultivated Glycyrrhiza were analyzed by the ICP-MS method. The г^2 values of elements standard curve were all above 0.99. The recovery rate was 91.21%～108.65%, RSD was 3.6%～8.9%. The results showed that this method was high accurate, little disturbance, rapid determination, simple operation. It can used for the determination of trace elements in Glycyrrhiza.
