Due to high need for medical purposes, multiple harvests of mugwort (Artemisia argyi) have been extensively applied in China for the increase of mugwort yield recently. However, the investigation on the mineral elements in different crops, which are significantly related to mugwort growth and the clinical efficacy of this medicinal herb, has not been conducted. This study provided an analytical method and quality evaluation for mineral elements in Nanyang mugwort leaves harvested from three different crops. The contents of 35 mineral elements were determined by inductively coupled plasma mass spectrometry (ICP-MS) and inductively coupled plasma atomic emission spectrometry (ICP-AES). ANOVA, principal component analysis and factor analysis were applied to evaluate the results. Four principal components were identified and their comprehensive evaluation function was as follows: F = 0.7008Fl + 0.1236F2 + 0.0936F3 + 0.0321F4. The comprehensive scores of the mugwort leaves from different crops were ranked as follows: 3rd crop > 2nd crop ≈ 1st crop. These findings can provide a reference for the quality control and clinical use of mugwort leaves, and a guidance of differential nourishing strategies for different crops.
由于医疗用途的巨大需求，最近中国广泛采用多次收获艾草（Artemisia argyi）的方法来提高艾草的产量。然而，对于与艾草生长和这种草药临床疗效密切相关的不同作物中的矿物质元素的调查尚未进行。本研究提供了一种分析方法和质量评价，用于测定来自三种不同作物的南阳艾草叶片中的矿物质元素。通过电感耦合等离子体质谱法（ICP-MS）和电感耦合等离子体原子发射光谱法（ICP-AES）测定了 35 种矿物质元素的含量。应用方差分析、主成分分析和因子分析对结果进行评价。确定了四个主成分，其综合评价函数如下：F=0.7008Fl+0.1236F2+0.0936F3+0.0321F4。不同作物艾草叶片的综合得分排名如下：第三茬>第二茬≈第一茬。这些发现可以为艾草叶片的质量控制和临床应用提供参考，也为不同作物的差异化营养策略提供指导。
