为了探索中药的微量元素,我们选择了常用的12种中草药,采用国产沈阳WYX—402型原子吸收分光光度计进行光谱测定分析。样品采用一般常规及湿法消化处理。分别测定药物中的Zn、Cu、Fe、Mn、Ca、Mg 等6种元素的含量,现将测定结果列表报告如下:常用12种中药的元素测定结果(P.P.M) In order to explore the trace elements of traditional Chinese medicine, we selected 12 commonly used Chinese herbal medicines, and used the domestic Shenyang WYX-402 atomic absorption spectrophotometer for spectrometric analysis. Samples were processed using conventional and wet digestion. The contents of six elements such as Zn, Cu, Fe, Mn, Ca, and Mg in the drug were measured, and the results of the test were reported as follows: Elemental determination results of 12 commonly used Chinese medicines (P.P.M)
