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 ICPMS.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-1which was accorded with the limits of medicinal plants and preparations for the import and export of green industry standards of China.
