摘要： Dried sclerotia of Wolfiporia extensa has a long history of a wide medicinal uses in Asia because of anti-inflammatory: effect. There is deficit of information on inorganic constituents of sclerotia. This study aimed at providing and evaluating data on some trace metals (Ag. As, Ba, Cd, Co, Cr. Cs, Cu, Li, Mn. Ni, Pb, Rh, Sr. TI. U, V, Zn) contents of sclerotia collected across Yunnan land in China. Sclerotia. when compared to fruiting bodies of fungi collected in wild, were low in toxic Ag: range (<0.005-0.21) mg/kg thy biomass (db); As: (< 0.0)14-0.041) mg/kg db; Cd: (< 0.002-0.034) mg/kg db; Pb: (0.020-0.24) mg/kg db and Tl: (< 0.001-0.015) mg/kg db. Sclerotia contained detectable amounts of essential trace metals such as Co: (0.0 II-0.21) mg/kg db; Cu: (0.44-3.8) mg/kg db; Li: (0.005-0.092) mg/kg db: Mn: (2.2-48) mg/kg db and Zn: (1.8-9.0) mg/kg db; were low in Rb: (0.11-2.8) mg/kg db and stable Cs ("'Cs): 1< 0.002-0.043) mg/kg db while relatively rich in Ba: (0.78-22) mg/kg db and Sr: (0.15-12) mg/kg db. The elements such as Cr. Ni and V occurred in sclerotia in different concentrations. Cr: (0.24-3.3) mg/kg db; Ni: (0.037-14) mg/kg db; V: (0.009-0.25) mg/kg db, and U: (< 0.001-0.015) mg/kg db. The sclerotia of W extensa from Yunnan were specifically enriched in Ba and Sr, and content of Mn was similar as showed for fruiting bodies of fungi foraged in Europe. The relatively high contents of Ba and Sr in the sclerotia examined could be attributed to a specific or anomalous geochemistry of soils in the regions of Yunnan.
