摘　　要：目的:对川产白芍中重金属及微量元素进行含量测定。方法:应用微波消解技术电感耦合等离子发射光谱法(ICP-OES)测定Hg、Cd、Pb、As、Cu、Zn、Se、Mn、Fe重金属及微量元素含量。结果:建立的各元素回归方程线性关系良好,相关系数在0.9997~1之间,加样回收率为91.09%~108.32%。结论:建立的微波消解-ICP-OES法简便、高效、准确,可用于白芍中重金属及微量元素的测定。Objective:To determine the contents of heavy metal and trace elements in Paeoniae Radix Alba in Sichuan. Method:The contents of Hg, Cd, Pb, As, Cu, Zn, Se, Mn and Fe were determined by microwave digestion-ICP-OES. Result:The established regression equation of each element had good linear relationship with the correlation coefficient of 0.9997~1.0000. The recoveries were 91.09%~108.32%. Conclusion:A simple, efficient and accurate method is established. It can be used for determination of heavy metal and trace elements from in Paeoniae Radix Alba.
