摘要
目的:测定中草药天花粉中Fe、Cu、Zn、Mn、Ca的含量。方法:样品经微波消解,采用火焰原子吸收法测定Fe、Cu、Zn、Mn、Ca的含量。结果:该方法快速、简便、准确,回收率为97.87%-103.94%,RSD为0.3175%~1.2226%。结论:天花粉中Ca含量较高,Mn含量极低。
Objective: To determine the content of 5 metal elements ( Fe, Cu, Zn, Mn, Ca) in Radix Triehosanthis. Methods: Sample was digested with microwave digestion system, and was determined by flame atomic absorption spectrometry(FAAS). Results:The method is simple,rapid and accurate. The reeovery was 97.87% - 103.94% ,RSD was 0. 3175% - 1. 2226%. Conclusions: The content of Ca in Radix Triehosanthis is high, but the content of Mn is low.
