摘　　要：目的:检测温里类和解表类各8种中药中7种微量元素的含量,并用主成分分析法分别对两类中药中的微量元素进行主成分分析比较。方法:应用ICP-AES法对温里类和解表类各8种中药中的Mg、Ca、K、Cu、Fe、Zn、Mn等7种微量元素进行测定,再进行主成分分析,两类药中各微量元素含量间的方差分析及差异性分析采用One-Way ANOVA分析。结果:温里类、解表类前三个因子的方差累计贡献率分别为84%和81%,主要影响元素分别为铁、锰、镁、锌和锌、铜、锰、铁。结论:两类药材中铜、铁、锌含量存在显著差异,这3种元素可以作为分类和功效研究的特征成分。Objective:To detect the contents of 7 trace elements in the two kinds of Traditional Chinese Medicines,and compare the trace elements by principal component analysis.Methods:Using ICP-AES method,Mg,Ca,K,Cu,Fe,Zn,Mn were determined in the two kinds of traditional Chinese medicines.Then the principal component analysis was carried out.The variance analysis and difference analysis between the trace elements in the two types of drugs were analyzed by One-Way ANOVA.Results:The cumulative contribution rates of variance of the first three factors were 84%and 81%respectively.Fe,Mn,Mg and Zn were the characteristic trace elements in warming interior Traditional Chinese Medicine,while Zn,Cu,Mn and Fe were the characteristic trace elements in relieving exterior Traditional Chinese Medicine.Conclusions:The contents of Fe,Cu,Zn in the two kinds of Chinese Medicines were significant differences,the characteristic trace elements of Fe,Cu,Zn could be characteristic components of classification and efficacy studies.
