摘要(Abstract)：

目的:研究不同来源天麻矿质元素含量,分析天麻特征元素及评价药材质量。方法:采用ICP法对不同来源的天麻药材必需的磷(P),钾(K),钙(Ca),镁(Mg),铁(Fe),锌(Zn),硼(B),锰(Mn),铜(Cu)等10种矿质元素含量进行测定,用主成分分析法分析天麻特征元素并对药材质量进行评价。结果:天麻药材中K元素含量最高,平均为15.31 g·kg-1;其次是N元素,平均含量为8.99 g·kg-12元素变异系数小;Mn元素含量的变异系数最大,为51.39%;N,P,K元素间达极显著正相关;主成分分析选择3个主成分对药材质量进行评价,发现天麻药材特征元素为P,B,N,K,Cu,Mn,Fe,Mg等8种元素。结论:天麻K和N元素含量高,且相对稳定;Mn元素含量差异大;其中P,B,N,K,Cu,Mn,Fe,Mg等8种元素是天麻特征元素;从矿质元素角度分析30份天麻资源中贵州、云南天麻药材质量较好。
Objective: To study the content of mineral elements and the principal components in Gastrodia elata. Method: Mineral elements were determined by ICP and the data was analyzed by SPSS. Result: Kelement has the highest content-and the average content was 15. 31 g·kg-1. The average content of N element was 8. 99 g·kg-1,followed by K element. The coefficient of variation of K and N was small,but the Mn was the biggest with 51. 39%. The highly significant positive correlation was found among N,P and K. Three principal components were selected by principal components analysis to evaluate the quality of G. elata. P,B,N,K,Cu,Mn,Fe and Mg were the characteristic elements of G. elata. Conclusion: The content of K and N elements was higher and relatively stable. The variation of Mn content was biggest. The quality of G. elata in Guizhou and Yunnan was better from the perspective of mineral elements.
