采用微波消解-电感耦合等离子体原子发射光谱法（ICP-AES）测定了云南省6个不同产地美味牛肝菌（Boletus edulis）菌盖和柄中P、Mg、Ca、Zn、Na、Cu、Ba、Ni、V、Cd、Sr、Co和Li的含量。结果表明，金牛肝菌子实体中P、Mg、Ca、Zn、Cu、Na含量较高，Ba、Cd、Ni、V、Li、Sr、Co含量次之，P、Mg、Zn、Cu含量在菌盖中高于菌柄。而Na、Ba、Cd、Ni、V、Li、Sr、Co等元素在楚雄姚安蘑菇柄中富集。研究结果表明，帽盖和柄之间元素的空间变异主要与不同基岩土壤地球化学特征和对各种元素的富集能力有关。
ICP-AES and microwave assisted digestion were applied to determine P, Mg, Ca, Zn, Na, Cu, Ba, Ni, V, Cd, Sr, Co, and Li in the caps and stipes of Boletus edulis collected from six spatially distant sites in Yunnan province, China. Fruiting bodies of King Bolete are abundant in P, Mg, Ca, Zn, Cu, and Na, followed by Ba, Cd, Ni, V, Li, Sr, and Co. Contents of P, Mg, Zn, and Cu are more abundant in caps than in stipes of King Bolete. However, elements such as Na, Ba, Cd, Ni, V, Li, Sr, and Co prefer to accumulate in stipes of mushrooms from Yaoan, Chuxiong. The results of this study indicate that spatial variations of elements between caps and stipes are mainly related to different bedrock soil geochemistry and enrichment capability for various elements.
