An inductively coupled plasma mass spectrometry (ICP-MS) or inductively coupled plasma atomic emission spectrometry (ICP-AES) was developed to determine 19 elements in safflower, a traditional Chinese medicinal herb from Xinjiang Autonomous Region and Henan Province of China. Totally 19 elements in safflower included heavy metals, i. e. As, Cd, Cu, Hg and Pb, and wholesome elements, i. e. Al, Ca, Co, Cr, Fe, Mg, Mn, Mo, Ni, P, Se, Sr, V and Zn. The results showed that the concentrations of heavy metals in safflower samples were both low, all of which met the national hygiene standards except for Pb in Xinjiang sample. Meanwhile, the distribution tendency of elements in the two samples was similar, which indicated that the plant might absorb given elements in a proportional way. The method can be used for the quality control of elements in safflower, and it provides a way for the determination of the contents of safflower from Xinjiang and Henan.
开发了电感耦合等离子体质谱法（ICP-MS）或电感耦合等离子体原子发射光谱法（ICP-AES）来测定来自中国新疆维吾尔自治区和河南省的传统中药材红花中的19种元素。红花中的19种元素包括重金属，即砷、镉、铜、汞和铅，以及有益元素，即铝、钙、钴、铬、铁、镁、锰、钼、镍、磷、硒、锶、钒和锌。结果表明，红花样品中的重金属含量均较低，除新疆样品中的铅外，所有重金属含量均符合国家卫生标准。同时，两个样品中元素的分布趋势相似，这表明该植物可能按比例吸收特定元素。该方法可用于红花中元素的质量控制，并为测定新疆和河南红花的含量提供了一种方法。
