摘　　要：目的:分析松杉灵芝微量元素含量,为松杉灵芝用药安全提供依据。方法:采用电感耦合等离子体质谱仪测定松杉灵芝中29种微量元素的含量。结果:松杉灵芝菌盖中重金属元素Pb含量为(4.21±0.29)μg·g-1,Cu含量为(12.55±1.12)μg·g-1,As含量为(1.26±0.08)μg·g-1,Cd未检出。松杉灵芝菌柄中重金属元素Pb含量为(3.63±0.04)μg·g-1,Cu含量为(16.59±1.24)μg·g-1,As含量为(1.58±0.05)μg·g-1,Cd未检出。松杉灵芝菌盖中Al,Fe,Zn,Mn含量比赤芝菌盖高。结论:松杉灵芝中重金属元素Pb<5μg·g-1,Cd<0.3μg·g-1,Cu<20μg·g-1,As<2.0μg·g-1,符合药用植物及制剂进出口绿色行业标准的限量标准。Objective： To analyze the content of microelement in Ganoderma tsugae and provide the basis for medication safety of G. tsugae. Method： The content of 29 microelement in G. tsugae was determined by ICP- MS. Result： In G. tsugae pileus, the content of heavy metals Pb, Cu, As was （4.21±0.29） , （ 12.55 ± 1.12） , and （ 1.26 ± 0.08） μg .g-1 respectively, Cd was not detected. In G. tsugaestipe, the content of heavy metals Pb, Cu, As was （3.63±0.04）, （16.59±1.24）, and （1.58±0.05） μg.g-1 respectively, Cd was not detected. The content of Al, Fe, Zn, Mn in G. tsugae pileus was higher than in stipe. Conclution： The content of heavy metals Pb, Cu, As, Cd in G. tsugaewas Pb 〈5 μg.g-1 Cd 〈0.3 μg.g-1 Cu 〈20 μg.g-1 As 〈2.0 μg.g-1 which was accorded with the limits of medicinal plants and preparations for the import and export of green industry standards of China.
