Several mushroom species are consumed by collecting from the nature or in cultured form for their nutritional and medical characteristics. The objective of the present study is to determine antioxidant activities, DNA-protective activities, total antioxidant status (TAS), total oxidant status (TOS), oxidative stress indices (OSI) and Fe, Mg, Zn, Cu, Na and Ca content in Auricularia auricula (L.) Underw. and Trametes versicolor (L.) Lloyd mushroom species. Mushroom ethanol extracts were obtained and antioxidant activities with DPPH method, TAS, TOS and OSI values with Rel Assay Diagnostics kits, and DNA protective activities using pBR322 supercoil DNA were identified. Furthermore, Fe, Mg, Zn, Cu, Na and Ca contents were determined with atomic absorption spectrophotometer. It was determined that antioxidant potential of mushroom ethanol extracts were low compared to the standard and they did not have DNAprotective activities. It was also observed that the mushrooms have variable element content, and have similar TAS, TOS and OSI levels. High OSI values found in both mushroom species showed that these mushroom are unhealthy. Thus, it was recommended to demonstrate caution in consumption of mushrooms collected in these regions. However, it was also considered that the mushroom samples collected from regions with adequate OSI values could be used as antioxidant.
