P, Na, Ca, Cu, Fe, Mg, Zn, As, Cd, Co, Cr and Ni, contents have been examined in caps and stipes of Boletus tomentipes collected from different sites of Yunnan province, southwest China. The elements were determined using inductively coupled plasma atomic emission spectroscopy (ICP-AES) with microwave digestion. P, Ca, Mg, Fe, Zn and Cu were the most abundant amongst elements determined in Boletus tomentipes. The caps were richer in P, Mg, Zn and Cd, and the stipes in Ca, Co and Ni. Cluster analysis showed a difference between Puer (BT7 and BT8) and other places. The PCA explained about 77% of the total variance, and the minerals differentiating these places were P (PC1) together with Ca, Cu, Fe, Mg, As and Ni, Na (PC2) together with Cd, and Zn (PC3). The results of this study imply that element concentrations of a mushroom are mutative when collected from the different bedrock soil geochemistry.
对采自中国西南部云南省不同地点的绒毛牛肝菌的菌盖和菌柄中的磷（P）、钠（Na）、钙（Ca）、铜（Cu）、铁（Fe）、镁（Mg）、锌（Zn）、砷（As）、镉（Cd）、钴（Co）、铬（Cr）和镍（Ni）含量进行了检测。采用微波消解-电感耦合等离子体原子发射光谱法（ICP-AES）测定这些元素。在绒毛牛肝菌中测定的元素中，磷、钙、镁、铁、锌和铜含量最为丰富。菌盖中磷、镁、锌和镉含量较高，菌柄中钙、钴和镍含量较高。聚类分析表明普洱（BT7和BT8）与其他地区存在差异。主成分分析（PCA）解释了约77%的总方差，区分这些地区的矿物质是磷（主成分1）以及钙、铜、铁、镁、砷和镍，钠（主成分2）以及镉，还有锌（主成分3）。本研究结果表明，从不同基岩土壤地球化学环境中采集的蘑菇，其元素浓度会发生变化。
