Abstract：The contents of eleven trace elements in Boletus tomentipes were determined by inductively coupled plasma atomic emission spectroscopy (ICP-AES). The results showed that the fruiting bodies of B. tomentipes were very rich in Mg and Fe (>100 mg·kg-1) and rich in Mn, Zn and Cu (>10 mg·kg-1). Cr, Pb, Ni, Cd, and As were relatively minor contents (0.1～10.0 mg·kg-1) of this species, while Hg occurred at the smallest content (<0.1 mg·kg-1). Among the determined 11 trace elements, Zn—Cu had significantly positive correlation (r=0.659, P<0.05), whereas, Hg—As, Ni—Fe, and Zn—Mg had significantly negative correlation (r=-0.672, -0.610, -0.617, P<0.05). This paper presented the trace elements properties of B. tomentipes, and is expected to be useful for exploitation and quality evaluation of this species.
