To investigate the distribution characteristics and correlation of inorganic element contents in Alismatis Rhizoma and rhizospheric soils from three habitats (Jianou, Fujian; Guangchang, Jiangxi; Pengshan, Sichuan).
The inorganic element contents were detected with inductively coupled plasma mass spectrometry (ICP-MS).
The results showed that inorganic element contents in Alismatis Rhizoma from different habitats presented regular distribution characteristics. In all samples, the contents of S, P, K, Mg and Ca were relatively high. The contents of S, P, K, Fe, Mg, Ca, Al and Zn in Alismatis Rhizoma from Fujian with low-content harmful heavy metal were more than those of other two places. Alismatis Rhizoma from different habitats showed remarkable ability to enrich P, S, Zn, Mg and Cu, especially to P and S. The contents of inorganic element in Alismatis Rhizoma and rhizosperic soil showed certain correlation.
These results provide scientific evidence for artificial modification of effective components biosynthesis in Alisma orientalis, and it could also provide a reference for forming mechanism of genuine characteristics and quality of Alismatis Rhizoma.
探究泽泻及其根际土壤中无机元素含量在3个产地（福建建瓯、江西广昌、四川彭山）的分布特征及其相关性。
采用电感耦合等离子体质谱法（ICP-MS）测定无机元素含量。
结果表明，不同产地泽泻中无机元素含量呈现一定规律的分布特征。所有样品中，硫、磷、钾、镁和钙的含量相对较高。福建泽泻中硫、磷、钾、铁、镁、钙、铝和锌的含量高于其他两地，且有害重金属含量较低。不同产地泽泻对磷、硫、锌、镁和铜均有显著富集能力，尤其对磷和硫。泽泻及其根际土壤中无机元素含量存在一定相关性。
这些结果为泽泻有效成分生物合成的人工调控提供了科学依据，也可为泽泻道地性形成机制及品质研究提供参考。
