摘　　要：利用电感耦合等离子体-原子发射光谱法(ICP-AES)测定不同采收时间(5、6、7、8月和9月)野生羌活药材中K、Na、Al 3种金属元素的含量,应用SPSS16.0分析软件对结果进行统计分析。研究结果表明,5—9月野生羌活药材中均以K元素含量最高;K和Na、Na和Al的含量呈负相关,K和Al的含量呈正相关;K元素的含量在5月到6月增加,6月到8月呈下降趋势,8月到9月急剧升高;Na元素的含量呈先上升(5—6月)后下降(6—9月)的趋势;Al元素的含量呈先降低(5—6月)再升高(6—9月)的趋势。The contents of K, Na and A1 in medicinal materials of wild Notopterygium incisum Ting ex H. T. Chang vegetated in different months （May, June, July, August, September） were determined by inductively coupled plasma optical emission spectrometer （ICP-AES）,and SPSS16.0 analysis software was applied to analyze the results. The content of K element was the highest in medicinal materials of wild Notopterygium incisum Ting ex H. T. Chang between May and September. K had a negative correlation with Na element and a positive correlation with A1 element,and Na had a negative correlation with A1 element. The content of K element increased from May to June,had a downtrend from June to August,raised sharply from August to September. The content of Na element elevated from May to June,reduced from June to September. The seasonal dynamics of A1 element was in contrary to Na element.
