This study aimed to discriminate the geographical origins of domestic and chinese Wolfiporia extensa. They were subjected to oxygen (45.32 to 48.07%), carbon (38.09 to 40.12%), hydrogen (6.05 to 6.78%), and nitrogen (0.16 to 0.23%). Antioxidant activity was examined by DPPH free radical scavenging activity. According to the results of the experiment, no significant differences were found between domestic (IC50, 7.25 mg/ml) and Chinese (IC50, 8.35 mg/ml) W. extensa. However, as determined by the inorganic mineral contents were significantly different between domestic and Chinese W. extensa. The amount of potassium in domestic and Chinese W. extensa was and 33.14 ± 17.27%, 47.60 ± 8.78%, respectively. The results of this study suggested that the analysis of inorganic components by ED-XRF should be useful for origin identification of W. extensa.
