We selected polypore mushrooms growing in the Mediterranean area of France to screen their antioxidant activity: <i>Ganoderma applanatum, G. lucidum, Inonotus cuticularis, I. hispidus, Trametes hirsuta</i>, and <i>T. versicolor</i>. Our work also evaluated antioxidant capacity from wild and cultivated <i>G. lucidum</i> fruiting bodies to optimize this biological property on human health. Dried fungal materials were sequentially extracted using cyclohexane, dichloromethane, ethanol, and water. Folin-Ciocalteu assay, oxygen radical absorbance capacity using DPPH and ORAC tests of the polypore extracts were assessed and compared. Among the 28 mushroom extracts tested, four exhibited significant antioxidant activity as ethanol extracts of <i>I. cuticularis, T. hirsuta</i> and wild and cultivated <i>G. lucidum</i>. The ethanol extracts of <i>I. cuticularis</i> and <i>T. hirsuta </i>revealed the highest values for the ORAC test, while the highest values for the Folin-Ciocalteu and DPPH tests were found for the ethanol extracts of cultivated <i>G. lucidum</i> and <i>I. cuticularis</i>. Further studies are needed to identify potential bioactive compounds, especially from <i>I. cuticularis</i> and <i>G. lucidum</i> grown under selected conditions and explore their benefits in the pharmaceutical and food industries.
