The . Abstract Mushrooms have been studied and found to accumulate a variety of second - ary metabolites with antioxidant activities such as phenolic compounds . Be - sides phenolics , other bioactive components such as flavanoids from mu - shrooms are also generally associated with antioxidant activities . Previous studies have reported the association of mushrooms with their antioxidant potentials . However , very few studies are related to unexplored Malaysian wild mushrooms as a new potential source of antioxidant for which to best of our knowledge , no records are available . In this study , ten Malaysian wild mushrooms were collected from the forests around Selangor and Sabah and their potential antioxidant activity were evaluated . The total phenolic content and total flavonoid content were quantified . Antioxidant activities of the mu - shroom extracts were analyzed by Ferric Reducing Antioxidant Power (FRAP) and 2 , 2 - diphenylpicrylhydrazyl (DPPH) assays for their iron - reducing capac - ity and free - radical scavenging capacity . The total phenolic content of all ten mushrooms ranged from 0 . 015 - 0 . 075 mg GAE / g dried extract and the total flavonoid content ranged from 0 . 025 - 0 . 131 mg QE / g dried extract . The FRAP values lies between 0 . 859 - 2 . 929 µM TE / g dried extract and the per - centage of inhibition observed from DPPH assay ranged from 2% - 57% re - spectively . There is a positive correlation between total phenolic content and antioxidant activities of these mushroom extracts .
