Atractylodes lancea (Thunb.) DC., is an important medicinal plant in China. Recently, researches of A. Lancea were focused on chemical composition and genetics, only a few were concerned with soil factors.
The aim was to discuss the relationship between geo-herbalism of A. Lancea (Thunb.) DC. and inorganic elements in soil.
The contents of 15 kinds of inorganic elements in the rhizoma of A. Lancea (Thunb.) DC. and soils from various regions were determined with inductively coupled plasma-optical emission spectrometer and the data were analyzed with Statistical Package for the Social Sciences 20.0 software.
The contents of inorganic elements in rhizoma of A. Lancea and in soil with different geological background were different. The soils in the famous region contained high aluminum, iron, sodium and low sulfur content. The rhizoma of A. Lancea contained high aluminum, lithium, manganese and low iron, sulfur content. The famous-region crude drugs had a strong tendency to accumulate selenium, manganese. Ten characteristic elements of A. Lancea were K, Ca, S, Al, Li, Ti, Mn, Pb, Ni, SE.
The contents of inorganic elements in rhizoma of A. Lancea showed a significant positive interrelationship with those in soil. It was identified that inorganic elements play an important role in forming authenticity A. Lancea (Thunb.) DC.
茅苍术是中国一种重要的药用植物。近年来，对茅苍术的研究主要集中在化学成分和遗传学方面，仅有少数研究关注土壤因素。
探讨茅苍术的道地性与土壤中无机元素之间的关系。
采用电感耦合等离子体发射光谱仪测定不同产地茅苍术根茎及土壤中15种无机元素的含量，并运用社会科学统计软件包20.0对数据进行分析。
不同地质背景下茅苍术根茎及土壤中无机元素含量存在差异。道地产区土壤中铝、铁、钠含量较高，硫含量较低。茅苍术根茎中铝、锂、锰含量较高，铁、硫含量较低。道地药材对硒、锰有较强的富集倾向。茅苍术的10个特征元素为钾、钙、硫、铝、锂、钛、锰、铅、镍、硒。
茅苍术根茎中无机元素含量与土壤中无机元素含量呈显著正相关。研究表明无机元素在茅苍术道地性形成中起重要作用。
