18种中药中微量元素铁锌锰铜的含量研究

Research for the Content of Trace Element Fe,Zn,Cu and Mn in 18 Chinese Herb Medicines

为研究治疗黄褐斑常用中药中Fe、Zn、Cu、Mn的含量与药效的关系,测定了18种中药材中Fe、Zn、Cu、Mn含量,并用主成分分析法进行分析。结果表明,Fe含量最高,Zn、Mn次之,Cu最少;Zn和Cu的相关系数最大,且Zn与Cu比均大于1。说明补充Zn可以抑制Cu与酶结合,防治色斑。

To research the relationship between the classes and the content of the trace elements such as Fe, Zn, Cu and Mn and the drug effect of the Chinese herb medicines which treat chloasma, the content of Fe, Zn, Cu and Mn in 18 Chinese herb medicines was determined, and the data by principle component analysis were analyzied. The result shows that the content of Fe is the highest, and Cu is the least. The related coefficient of Zn and Cu is the highest, and the ratio of Zn and Cu is more than 1. So the ingestion of Zn can inhibit Cu to combine enzyme and cure chloasma.
