Objective: To elucidate the phytochemical content and antioxidant activity of selected wild\udedible Nigerian mushroom species.\udMethods: Phytochemical screening was carried out using standard methods while 1,1-Diphenyl\udpicryl hydrazyl (DPPH) radical and reductive power assays were used to evaluate the in vitro\udantioxidant properties of the selected edible Nigerian mushroom species.\udResults: The result obtained revealed the presence of alkaloids, cardiac glycosides, saponins,\udflavonoids, terpenes, steroids, tannins and phenols in the selected mushrooms extracts. The\udextract of Pleutorus ostearus showed a significantly (P<0.05) higher total phenol and flavonoid\udcontent of (248.80依7.63) mg/g and (42.63依0.63) mg/g respectively compared to other mushroom\udextracts. Cantherale cibarus had the most significant (P<0.05) amount of alkaloids [(135.57依0.27)\udmg/g] and saponins [(150.41依0.50) mg/g] when compared to other extracts while the tannin content\ud[(170.56依0.74)] mg/g was highest in the mushroom Temitomyces robustus. All mushroom extracts\udscavenged DPPH radical in a dose dependent manner. However, Lactarus deliciousus had the\udhighest DPPH scavenging activity compared to the other mushroom extracts. Pleutorus ostearus\udand Lactarus deliciousus had better reductive power than other mushroom extracts concentrations\udused.\udConclusions: The mushroom species analysed have been shown to be good sources of\udantioxidants and other phytoconstituents, thus it can be used in the management of oxidative\udstress induced diseases
