In order to establish a method for the simultaneous determination of trace elements Al, As, B, Ca, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Ni, P, Si, Ti, and Zn in Corydalis conspersa and Corydalis linarioides, we collected the samples from different areas and treated with acid hydrolysis into tissues to be detected by the way of inductively coupled plasma-atomic emission spectrometry compared with the standard element control method. We can know that the contents of Al, Ca, Fe, K, Mg, Na, and P in roots, stems, leaves, and flowers were higher. The contents of elements in different tissues and areas were as follows: flower > leaf > stem > root, Zeku County > Guide County > Nangqian County > Henan County. Among them, the contents of each element in the flowers of Maixiu Forest Farm were higher, while the contents of B, Cr, Cu, Li, Mn, Ni, Si, Ti, and Zn in roots, stems, and leaves of other areas were lower. The contents of heavy metal elements complied with the limit degree. A 3-factor model was obtained by principal component analysis which could clarify 82.46% of the total experimental data; the factors of Al, Fe, Mg, Na, P, Ca, Cu, Si, and Zn had great influence on the efficacy of 21 kinds of medicinal materials. Cluster analysis classified the samples into three categories; the flowers of Corydalis conspersa and stems of Corydalis linarioides from different collection areas are clustered containing high contents of type 1 and 3 characteristic components; the roots, stems, and leaves from other collection areas are clustered with low contents of 1 and 2 characteristic components. It can be used for the determination of trace elements in Corydalis conspersa and Corydalis linarioides to provide effective basis for revealing the function of trace elements with plant growth.

ICP-AES 测定紫堇和紫堇中的微量元素

建立同时测定紫堇中微量元素Al、As、B、Ca、Cr、Cu、Fe、K、Li、Mg、Mn、Na、Ni、P、Si、Ti、Zn的方法和紫堇属植物，我们收集了不同地区的样品，并用酸水解处理成组织，通过电感耦合等离子体原子发射光谱法与标准元素对照法进行比较。可知根、茎、叶、花中Al、Ca、Fe、K、Mg、Na、P的含量较高。不同组织和区域的元素含量为：花>叶>茎>根，泽库县>贵德县>囊迁县>河南县。其中，麦秀林场花中各元素含量较高，而B、Cr、Cu、Li、Mn、Ni、其他地区根、茎、叶中Si、Ti、Zn含量较低。重金属元素含量符合限量标准。通过主成分分析得到了一个三因子模型，可以澄清总实验数据的82.46%；Al、Fe、Mg、Na、P、Ca、Cu、Si、Zn等因素对21种药材的药效影响较大。聚类分析将样本分为三类；不同采集地延胡索的花和延胡索的茎聚集在一起，含有高含量的1型和3型特征成分；来自其他采集区的根、茎和叶聚集在一起，1 和 2 特征成分的含量较低。
